A REVISION OF PASSIFLORA SECTION DYSOSMIA

Revision of Passiflora subgenus Passiflora section Dysosmia DC. (Passifloraceae). The twenty one species and 10 varieties (31 taxa) comprising subgenus Passiflora section Dysosmia DC are described and some are illustrated with photographs and line drawings. Two species, Passiflora vesicaria L. and Passiflora ciliata (Dryand) Mast., are removed from synonymy and reinstated to species rank. Passiflora baraquiniana Lemaire is removed from synonymy and given varietal status. The species Passiflora santiagana (Killip) Borhidi is reduced in rank to varietal status. Of the 38 varieties of Passiflora foetida L. described by E. P. Killip in his 1938 monograph, 28 are reduced to synonymy, four are reassigned as varieties of other species and four remain as varieties of P. foetida. A new variety, Passiflora foetida var. ellisonii Vanderplank, is described with photographs and line drawings.     

Synopsis ofVerbesina sect.Ochractinia (Asteraceae)

A taxonomic revision ofVerbesina sect.Ochractinia is presented. 40 species plus 7 additional infraspecific taxa are recognized. A table of the distribution of the species, key to the species and synonymy are included. Relationships to other sections ofVerbesina and species relationships within sect.Ochractinia are discussed.     

Chemical variation in two species of theLecanora subfusca group (Lecanoraceae,lichenizedAscomycotina)

The chemical variation inLecanora epibryon andL. subimmersa, two species of theL. subfusca group, has been examined. In both species the chemical differences are correlated with geographical distribution, but not with morphological differences. As a consequence the chemotypes are recognized at subspecific level. InL. epibryon three chemical races are segregated according to the various chemosyndromes present. Subspeciesepibryon, containing atranorin and triterpenoids, occurs in the northern hemisphere and South America, while the other two subspecies occur only in the southern hemisphere. The subsp.broccha (Nyl.)Lumbsch, comb. nova, contains atranorin, the stictic acid and the 2,5,7-trichloro-3-O-methylnorlichexanthone chemosyndromes, while subsp.xanthophora Lumbsch, subsp. nova, is similar but lacks the stictic acid chemosyndrome. Two chemical races occur in the pantropical speciesL. subimmersa. While subsp.subimmersa contains atranorin and zeorin, subsp.ramboldii Lumbsch & Elix, subsp. nova, contains an additional ten chlorinated xanthones.L. impressa is reduced to synonymy toL. subimmersa.     

中国橐吾属(菊科-千里光族)的分类学研究(四):康定橐吾和Senecio ficariifolius的名实订正(英文)

将康定橐吾(Ligularia kangtingensis S.W.Liu)处理为细茎橐吾[L.hookeri(C.B.Clarke)Hand.-Mazz.]的异名。Senecio ficariifolius H.Lév.Vaniot长期以来被处理为细茎橐吾的异名,但我们检查模式材料后发现其头状花序盘状,与头状花序辐射状的细茎橐吾明显不同,而与头状花序盘状的贵州橐吾[L.leveillei(Vaniot)Hand.-Mazz.]没有区别,故将其处理为贵州橐吾的异名。     

On Neodiaptomus schmackeri (Poppe & Richard, 1892) (Crustacea,Copepoda)

The louse Menacanthus obrteli Balát, 1981 is resurrected from synonymy as a valid species, with Locustella luscinioides, the Savi’s warbler, as the type-host. Both sexes of this louse species are redescribed and illustrated.     

Collapse of species boundaries in the wild potatoSolanum brevicaule complex (Solanaceae, S. sect.Petota): Molecular data

TheSolanum brevicaule complex is a group of morphologically very similar wild and cultivated potato taxa (Solanum sect.Petota). This study uses single to low-copy nuclear RFLPs and RAPDs to investigate their species boundaries and relationships. Cladistic analyses of both data sets are largely concordant with each other and with a recently published phenetic analyses of the same accessions using morphology. All three data sets separate members of the complex into populations from Peru and immediately adjacent northwestern Bolivia, including most cultivated species accessions, and populations from northwestern Bolivia to Argentina. The molecular results suggest that the complex is paraphyletic as currently circumscribed. Many species of theS. brevicaule complex should be relegated to synonymy.

研究欧洲和中国的标本后发现,室翅长蝽科Heterogastridae的小异腹长蝽Heterogaster minimusZou&Zheng,1981是地长蝽科Rhyparochromidae的红足点胸长蝽Acompus rufipes(Wolff,1804)的新异名。文中还提供了红足点胸长蝽Acompus rufipes的整体图和雄性生殖器特征图。     

Revision and reclassification of three Plasmopara species based on morphological and molecular phylogenetic data

Based on the results of morphological and DNA sequence (partial D1–D3/D7–D8 nuLSU and partial nuSSU-ITS1-5.8S rDNA) data, three species of Plasmopara are revised and reclassified. A species of Plasmopara parasitic on Scorzonera, invalidly published several times, is assigned to a new genus and species under Novotelnova scorzonerae. Plasmopara euphrasiae sp. nov. is segregated from P. densa, and P. centaureae-mollis is revised and relegated to synonymy of Bremia centaureae. All taxa are described and illustrated.

A review of the systematic position of the North American species of the genusGlyptotendipes

The systematic position of the North American species of the genusGlyptotendipes is reviewed using morphological characters from all life history stages. The cladistic analysis revealed adult characters which support the monophyly of the three species groups (A, B and C) of PINDER and REISS (1983, 1986) for pupae and larvae. These species groups are given formal subgeneric status, with Group A becomingGlytotendipes, s.s., placingPhytotendipes Goetghebuer, 1937 in synonymy, Group B is namedCaulochironomus (type-species,Tendipes caulicola Kieffer, 1913) and Group C is namedTrichotendipes (type-species,Tendipes signatus Kieffer, 1911).     

Lipochaeta and Melanthera (Asteraceae: Heliantheae subtribe Ecliptinae): establishing their natural limits and a synopsis

We restrict the genusLipochaeta to the allopolyploid species of the typical section.Lipochaeta s.str. is interpreted to be the result of an intergeneric hybridization betweenMelanthera and a presently unknown taxon, perhaps of the genusWedelia. Lipochaeta is characterized, in addition to its allopolyploidy (n=26), by having both flavonols and flavones, disk corollas with 4 lobes, achenes tuberculate at maturity, the disk achenes flattened to slightly biconvex, and ray achenes obcompressed.Lipochaeta sect.Aphanopappus andWollastonia are here reduced to synonymy underMelanthera. We transfer 14 HawaiianLipochaeta and one New Caledonian species as well as the AsianWedelia prostrata toMelanthera. These transfers, along with the species in Africa and North America, bring the number of species in the genus to 35.Melanthera is delimited by an abruptly narrowed to truncate and flattened top of the achene, (0−)1–15(−20) often unequal, ciliate or barbellate, caducous pappus bristles immediately surrounding the corolla, involucral bracts and receptacular paleae with many veins forming longitudinal striations, and n=15. The florets are 5-merous, the corollas are yellow or white, and rays are absent (in white-flowered species) or present and neutral or fertile. In dealing with species formerly placed inLipochaeta, the GalapagosL. laricifolia is here transferred from the illegitimate generic nameMacraea toTrigonopterum and the BrazilianL. goyazensis is transferred toAngelphytum. We maintain the earlier reduction ofEchinocephalum underMelanthera and reduce all three taxa originally described in it to one,M. latifolia.     

Taxonomic novelties in <Emphasis Type="Italic">Rhynchospora</Emphasis> (<Emphasis Type="Italic">Cyperaceae</Emphasis>) from South America
