New taxa and combinations in Calceolaria (Scrophulariaceae) from Peru and Bolivia

As a result of field work in Peru and Bolivia 1982–83, and herbarium studies, 21 new taxa are described and two new combinations are made in Calceolaria. The following species are described as new: C. sclerophylla, C. arbuscula , and C. crassa of sect. Sa–licifoliae; C. rupestris of sect. Revolutae; C. micans, C. laevis, C. rariflora , and C. concava of sect. Teucriifoliae; C. bullata and C. neglecta of sect. Parvifoliae; C. amoena and C. ramosa of sect. Polyclada; C. pilosa, C. incana, C. hirsuta , and C. cordifolia of sect. Urticopsis; C. cumbemayensis of sect. Lobatae; and C. caespitosa of sect. Scapiflorae. Three new subspecies are described: C. deflexa R. & P. ssp. cuneata and C. salicifolia R. & P. ssp. nigricans of sect. Salicifoliae , and C. hispida Benth. ssp. acaulis of sect. Lobatae. Two new combinations are proposed: C. melissifolia Benth. ssp. pseudoscabra (Edwin) Molau of sect. Teucriifoliae , and C. llamaensis (Edwin) Molau of sect. Anacyrta. The taxon Revolutae is raised to the sectional level, and the sections Polyclada and Parvifoliae are emendated. Chromosome numbers are reported for C. sclerophylla (2n = 36), C. micans (2n = 72), C. laevis (2n = 72), C. melissifolia ssp. pseudoscabra (2n = 36), C. neglecta (2n = 36), C. cumbemayensis (2n = 36), and C. hispida ssp. acaulis (2n = 36).     

The genus Calceolaria in NW South America. VI. The sections Urticopsis, Lobatae and Micranthera

Three sections of Calceolaria (Scrophulariaceae) in NW South America are revised, viz. sect. Urticopsis (8 species in the area), Lobatae (4), and Micranthera (2). Sect. Urticopsis is characterized by herbaceous, ovate, petiolate leaves and white to buffish pubescence. Sect. Lobatae is characterized by lobate, petiolate leaves and white to greyish white pubescence. Sect. Micranthera comprises small herbs with a weedy habit, characterized by small anthers and unusually long filaments. Three new species are described, viz. C. obtusa, C. trichanthera , and C. adenocalyx (all in sect. Urticopsis) , and one new combination is made, viz. C. penlandii ssp. puraceensis (sect. Urticopsis). Chromosome numbers (all 2n = 36) are reported for C. lamiifolia, C. obtusa, C. penlandii ssp. penlandii , and C. dichotoma.     

Further research on chemotaxonomy of paeonol and analogs in Paeonia (Ranunculaceae)

In this paper, the paeonol, paeoniflorin and their analogs were analyzed in the roots of 14 species and 2 subspecies of Paeonia L. The existence and content of these compounds were discussed in three sections, sect. Moutan, sect. Paeonia and sect. Onaepia. In sect. Moutan, paeonol and its analogs were high in content in all species. In sect. Paeonia, low content of paeonol and its analogs were found in plants of four taxa, P. lactiflora, P. anomala ssp. veitchii, P. mairei and P. intermedia. None of these compounds was found in sect. Onaepia. Paeonol has a simple structure and is distributed widely in plant; its decrease and loss may be the result of evolution. Therefore, it is deduced that the relationship among the three sections of Paeonia might be that woody sect. Moutan is the more primitive and derived from the ancestor of Paeonia first. For the herbaceous sections, sect. Paeonia is more closely related to sect. Moutan than to sect. Onaepia. In sect. Moutan, there are less paeonol and its analogs in the species of subsect. Vaginata than in those of subsect. Delavayanae. Thus, the former may be considered more advanced. In sect. Paeonia, the taxa with minor content of paeonol and its analogs are diploid except P. mairei. Among them, P. lactiflora and P. anomala ssp. veitchii are relatively primitive by morphology. None of paeonol and its analogs was detected in the species with specialized form.     

芍药属牡丹组分类新注

自我们近年发表一系列牡丹组分类文章以来, 国内外基本上赞同我们8个种的分类系统,但对一些问题仍有不同见解。本文进一步申述牡丹Paeonia suffruticosa Andrews 是一个独立的种而不是人工杂种, 以及银屏牡丹P. suffruticosa ssp. yinpingmudan是牡丹P. suffruticosa的野生类型而不是逸生的P. ostii的理由。上述论点也得到了分子树的支持。P. jishanensis T. Hong &; W. Z. Zhao是一个合法名称, 而P. spontanea (Rehder) T. Hong &; W. Z. Zhao则确实是一个多余名。太白山紫斑牡丹的学名应是P. rockii ssp. atava (Brühl) D. Y. Hong &; K. Y. Pan, 因此P. moutan Sims ssp. atava Brühl不应是可疑的分类群。本文还对Halda的6个组合和两个杂交种名作了处理。结果, 本文包括了5个新异名和一个新组合。     

A revision of Tecoma Juss. (Bignoniaceae) in Bolivia

A revision of the genus Tecoma in Bolivia based on the author's herbarium research and extensive field observations is presented. Species delimitation is re-evaluated, resulting in the recognition of only four species, one of which, T. beckii J. R. I. Wood, is described as new. Tecoma sambucifolia is treated as var. sambucifolia (Kunth) J. R. I. Wood of the widespread and variable T. stans (L.) Juss., as it can only be distinguished on the basis of minor morphological characters and is not as geographically restricted as has been supposed. Tecoma fulva (Cav.) D. Don is treated as a variable species extending from central Peru to Chile and northern Argentina with six subspecies: ssp. fulva , ssp. guarume (A. DC.) J. R. I. Wood, ssp. tanaeciiflora (Kränzlin) J. R. I. Wood, ssp. arequipensis (Sprague) J. R. I. Wood, ssp. garrocha (Hieron.) J. R. I. Wood, and ssp. altoandina J. R. I. Wood, the latter described as new. The differences between T. tenuiflora (A. DC.) Fabris and the Peruvian T. rosifolia Kunth are discussed. Hybrids are formally recognized in the genus for the first time, and the implications for the accepted corolla morphology and pollination syndromes are discussed. Maps illustrate the geographical distributions of the species. All taxa discussed in the paper are illustrated.  © 2008 The Linnean Society of London, Botanical Journal of the Linnean Society , 2008, 156 , 143–172.     

The genus Calceolaria in NW South America VIII. The section Calceolaria and appendices to parts I–VIII

Sect. Calceolaria (= Aposecos) of Calceolaria (Scrophulariaceae) in NW South America is revised, and the other species of the section are briefly discussed. The section comprises annual herbs with somewhat succulent stems and leaf–blades that are usually pinnately dissected (pinnatifid). Four species are recognized in the investigated area, viz. C. mexicana, C. tenuis, C. tripartita , and C. chelidonioides , and their chromosome numbers are reported (2n = 32, 60, 64, and 60 respectively). The basic number in sect. Calceolaria is x = 8. Two new combinations are made, viz. C. mexicana ssp. prostrata (Kränzlin) Molau and C. mexicana ssp. perijensis (Pennell) Molau. The species of sect. Calceolaria are intersterile and facultatively autogamous, and each species comprises numerous pure lines, some of which may be morphologically discernible.
In the appendices, chromosome numbers are listed and the occurrence of elaiophores in all NW South American species of Calceolaria is indicated. The chromosome numbers of C. crenata ssp. australis, C. adenanthera, C. gossypina, C. semiconnata, C. stricta, C. sericea , and C. comosa (all 2n = 36) have not previously been reported. A revised key to the sections of Calceolaria in NW South America is also provided.

薯蓣属根状茎组基于3个cpDNA序列的分子系统研究

Seventeen species, one subspecies and one variety of Dioscorea sect. Stenophora Uline were investigated for their phylogenetic relationships based on a sequence analysis of chloroplast matK and rbcL genes and trnL-F intergenic spacer by maximum parsimony and maximum likelihood methods. The results showed that (a) sect. Stenophora was a strongly supported monophyletic group; (b) D. rockii, D. membranacea, D. banzhuana, and D. simulans formed a moderately supported monophyletic group, and D. prazeri was weakly supported to be sister to this group; (c) D. althaeoides and D. nipponica ssp. nipponica formed a moderately supported clade, and D. nipponica ssp. rosthornii was not a member of this clade; (d) D. zingiberensis and D. sinoparviflora showed a moderate to strong sister relationship; and (e) D. collettii var. hypoglauca and D. collettii var. collettii were sister to each other, but with only weak support.     

Notes on South Greenland vascular plants. Pteridophytes and gymnosperms

Taxonomical and nomenclatural notes worked out during a phytogeographical study of South Greenland are published. It is shown that the Greenland representative of Polypodium belongs to the American P. virginianum and not to the Eurasian P. vulgare. The following changes are made: Diphasiastrum complanatum (L.) Holub f. montellii (Kukk.) J. Feilberg comb, et stat. nov. and Isoetes lacustris L. ssp. pauper–cula (Engelm.) J. Feilberg stat. nov. The last mentioned change has to be made here when treating ssp. lacustris , which is the taxon present in Greenland.     

以礼草属的分类研究

以礼草属Kengyilia Yen et J. L. Yang 是禾本科Poaceae小麦族trib．Triticeae中新近建立的屑,针对其存在问题,对它进行了全面清理,提出了一个新的分类系统。新系统含3组、26种、6变种,其中3个组为新设立,并包括1新种、7个新等级、新组合及新异名。此外,还报道了一些类群的分布新记录。     

A taxonomical study on the genus Kengyilia Yen et J. L. Yang

Kengyilia Yen et J L Yang is a recently established genus in trib. Tritieeae of Poaceae. In this paper, this genus is taxonomically revised, and a new taxonomic system is presented. The new system includes 3 sections, 26 species and 6 varieties, of which 3 sections and 1 species are described as new, 7 taxa are treated respectively in the ways of new status or combination and reduction. Three new sections, sect. Kengyilia, sect. Stenachyra L. B. Cai and sect. Hyalolepis (Nevski) L. B. Cai, are differentiated by the length and width of spike, the growing position of spikelet, the relative length of glume, the colour of anther and so on. The sect. Kengyilia contains 9 species, distributed in northwestern China, extending westward to Kazakhstan, Kirghizia, Tadzhikistan, Afghanistan and Iran; the sect. Stenachyra L. B. Cai comprises 10 species and 3 verieties, distributed in western China, mainly in the Qinghai-Xizang Plateau; and the sect. Hyalolepis (Nevski) L. B. Cai consists of about 7 species and 3 varieties, distributed in western China, extending westward to Kirghizia and Tadzhikistan. Twenty-six species of Kengyilia are recognized on the basis of the same criterion of specific concept, and the other taxa below the rank of species are also checked in terms of their external morphology. As a result, Kengyilia pen~ dula L. B. Cai is reported as a new species; K. hirsuta var. obviaristata L. B. Cai is raised to a species; K. melanthera (Keng) J. L. Yang, Yen et Baum is reduced to a variety under K. thoroldiana (Oliver) J. L. Yang, Yen et Baum; Roegneria hirsuta var. leiophylla Keng et S. L. Chen is reduced as a synonym of K. hirsuta var. hirsuta; Agropyron thoroldianum var. lasciusculum Melderis is reduced to K. grandiglumis (Keng et S. L. Chen) J. L. Yang, Yen et Baum; Roegneria rigidula var. intermedia Keng et S. L. Chen to K. rigidula (Keng et S. L. Chen) J. L. Yang, Yen et Baum; R. hirsuta var. variabilis Keng et S. L. Chen and R. rnelanthera var. tahopaica Keng et S. L. Chen to K. hirsuta (Keng et S. L. Chen)J. L. Yang, Yen et Baum. In addition, new records onthe geographical distributions of some taxa are also reported in this paper.

The acaulescent and succulent species of Dorstenia sect. Kosaria (Moraceae) from NE tropical Africa and Arabia

The acaulescent and succulent species of Dorstenia sect. Kosaria in NE tropical Africa include the well defined D. ellenbeckiana and the two polymorphic taxa, the D. barnimiana complex and the D. foetida complex. The D. barnimiana complex is treated as two species, D. barnimiana Schweinf. and D. tropaeolifolia (Schweinf.) Bureau. One specific name and four varietal names are reduced to synonymy. The D. foetida complex is treated as one species, D. foetida (Forssk.) Schweinf., with two subspecies, ssp. foetida and ssp. lancifolia (Rendle) Friis comb, nov., of which the former is further divided into var. foetida and var. obovata (A. Rich.) Schweinf. & Engl. Three species arc reduced to synonymy of D. foetida. The distribution of all the species is mapped.     

A revision of the genus Lasianthus (Rubiaceae) in Africa, excluding Madagascar

23 species, one subspecies and three varieties have been described or named for the pan-tropical genus Lasianthus Jack (Rubiaceae) in continental Africa. In the present revision thirteen species, five subspecies and one variety are recognized; additionally two hybrids are proposed. Of the previously named taxa, the subspecies is raised to species rank whereas two species are degraded to subspecies and variety status, respectively. Five species are synonymised including two varieties, and four are left with uncertain status, including one variety. The distribution of the genus in Africa consists of two distinct elements: one component is found in the Guineo-Congolian regional centre of endemism and one in the eastern part of Afiomontane Archipelago-like regional centre of endemism. A centre of species diversity is found in Eastern Arc Mts., where six endemic species occur together with L. laxinervis and the more widespread L. kilimandscharicus. Four of the species are strict endemics of the Uluguru Mts. In addition to the presentation of the new section: Lasianthus Sectio Membranacei, sect. nov., this revision contain two hybrids from Uluguru Mts.: L. macrocalyx × pedunculatus and L. cereifizorus × pedunculatus, and following new taxa and new combinations: L. africanus ssp. biokoensis, subsp. nov.; L. africanus ssp. mayumbensis, comb. et stat. nov.; L. kilimandscharicus ssp. glabrescens, ssp. nov.; L. kilimandscharicus ssp. glabrescens var. xanthospermus, comb. et stat. nov.; L. kilimandscharicus ssp. hirsutus, ssp. nov.; L. laxinervis, stat. nov.; L. pedunculatus ssp. angustisepalus, ssp. nov.     

Classification of Primula sect. Auricula (Primulaceae) based on two molecular data sets (ITS, AFLPs), morphology and geographical distribution

On the basis of the study of c . 1100 herbarium specimens, field observations and molecular (ITS, AFLPs) evidence, Primula sect . Auricula is classified into two subsections, 25 species and six subspecies. Primula auricula L. ssp. widmerae (Pax) L. B. Zhang stat. nov. , P. auricula Linn. ssp. tatriaca L. B. Zhang ssp. nov. , and P. latifolia Lapeyr. ssp. cynoglossifolia (Widmer) L. B. Zhang stat. nov. are newly described or combined; P. auricula s.l. is divided into two species: P. auricula Linn. and P. balbisii Lehm., representing the northern and the southern populations of P. auricula s.l. resolved in the molecular study, respectively; P. cottia Widmer and P. balbisii Lehm. are recovered from synonymy; P. grignensis D. M. Moser and P. pedemontana E. Thomas ex. Gaudin ssp. iberica Losa et P. Monts. are synonymized with P. hirsuta All. and P. pedemontana , respectively; P. clusiana is postulated to be an allopolyploid species. Phylogenetic relationships in the section are discussed based on morphological and molecular variation and geographical distribution.  © 2004 The Linnean Society of London, Botanical Journal of the Linnean Society , 2004, 146 , 1–26.     

Karyotaxonomy of Greek serpentine angiosperms

The chromosome numbers are given for 20 angiosperm taxa, most of which grow predominately or exclusively on serpentine in Greece, and the karyotype morphology is illustrated in all cases but one. Chromosome data are provided for the first time for ten taxa ( Alyssum pogonocarpum, Centaurea charrellii, C. vlachorum, Cephalaria fanourii, Matricaria tempskyana, Onosma stridii, Scorzonera doriae, Silene fabarioides, S. salamandra, Trinia glauca ssp. pindica ) and for the endemic monospecific genus Leptoplax . A new number is reported for Thymus teucrioides ssp. candilicus . An unexpected dysploid number is recorded for a population of Leontodon hispidus ssp. hispidus. Chromosome number and karyotype details from Greek populations are presented for the rest of the taxa. Chromosomal evidence supports close relationships among members of Onosma subsect. Asterotricha . The unusual chromosome number of Centaurea vlachorum supports its placement either in C. sect. Jacea or C . sect. Cyanus . The evolution of taxa in sections Vierhapperia, Pulvinares , and Nervosae of Scorzonera appears to be connected with particular chromosomal rearrangements and dysploidy. Leptoplax does not share the same chromosome number with Peltaria but with Bornmuellera instead, something that facilitates infrageneric hybridization. Further issues of taxonomy, distribution, evolution and conservation of serpentine species are briefly discussed where appropriate. © 2002 The Linnean Society of London , Botanical Journal of the Linnean Society , 2002, 139 , 109–124.     

A synopsis of Central American Theophrastaceae

A synoptical revision of the Theophrastaceae in Central America is presented. Three genera are recognized, viz. Clavija (5 spp.), Deherainia (2 spp.), and Jacquinia (11 spp.). Four taxa are described as new to science, viz. Clavija fusca (Panama), Jacquinia nitida (Nicaragua, Honduras, Guatemala), J. montana (Nicaragua), and Deherainia smaragdina ssp. occidentals (Mexico, Veracruz). Three new combinations are proposed, viz. Clavija mezii ssp. allenii, Jacquinia macrocarpa ssp. pungens , and J. m. ssp. panamensis. Variation in reproductive characters, indumentum, and foliar anatomy is briefly reviewed.
