A new species of Valantia , V. lainzii Devesa & Ortega-Olivencia, endemic to the coastal zone of Granada (southern Spain) is described. The species recalls V. muralis L. in its general aspect, and V. deltoidea Brullo in the type of fructiferous body.  © 2003 The Linnean Society of London, Botanical Journal of the Linnean Society , 2003, 143 , 331–335.  相似文献

Astragalus neo-assadianus (Fabaceae), a new species endemic to Iran, is described and illustrated. This species belongs to A. sect . Alopecuroidei and is distinct and interesting among the Iranian species. It is confined to the north-eastern part of Iran (Khorasan Province) and only known from a single collection close to the Turkmenistan frontier.  © 2003 The Linnean Society of London, Botanical Journal of the Linnean Society , 2003, 143 , 197–200.  相似文献

A new species of Hybanthus (Violaceae) from north-eastern Brazil is described and illustrated. Hybanthus verrucosus Paula-Souza is endemic to 'caatingas' of Bahia and Alagoas states and is very distinct from all other Brazilian species of the genus, for its anterior petal, which is covered with small wart-like outgrowths. Other distinctive characteristics of the new species and its relationship with a closely related species ( H. atropurpureus (A.St.-Hil.) Taub.) are discussed.  © 2003 The Linnean Society of London, Botanical Journal of the Linnean Society , 2003, 141 , 503–506.  相似文献

A re-evaluation of Minuartia graminifolia has been undertaken based on comparative morphological studies. M. graminifolia subsp. rosani (an endemic of the south-central Apennines and Sicily) and subsp. hungarica (an endemic of the Banat region of Romania) are accepted infraspecific taxa. M. graminifolia subsp. hungarica is lectotypified. M. graminifolia subsp. clandestina is confirmed for Italy; the taxon is neotypified. The type subspecies is considered an endemic to the east-central Alps. Keys to the species of Minuartia ser. Graminifoliae and to the subspecies of M. graminifolia are provided.  © 2003 The Linnean Society of London, Botanical Journal of the Linnean Society , 2003, 143 , 419–432.  相似文献

Two new species of the genus Galium are described from the Iberian Peninsula: G. moralesianum Ortega-Olivencia & Devesa, and G. talaveranum Ortega-Olivencia & Devesa. The first grows on limestone or dolomitic-limestone outcrops in south-east Spain (the Segura and Gádor mountain ranges) and shows morphological similarities with G. boissieranum Ehrend. & Krendl, which is endemic to southern Spain (mountains of Málaga). The second inhabits the margins of water courses, alder stands and cork-oak dehesas (parkland-type systems) of the west of the Iberian Peninsula, and is morphologically reminiscent of G. mollugo L. The chromosome numbers of these two species and of G. boissieranum are given.  © 2003 The Linnean Society of London, Botanical Journal of the Linnean Society , 2003, 143 , 177−187.  相似文献

Preliminary checklist of the orchids of Chile   总被引:1,自引:0,他引:1  
This article provides a preliminary checklist of the orchids occurring in Chile, based on historical and recently published literature. Data compilation was assisted by using databases available on the Web (IPNI, W3Tropicos and KR). The list comprises seven genera ( Aa , Bipinnula , Brachystele , Chloraea , Codonorchis , Gavilea and Habenaria ) and 50 taxa (49 species and one variety), 25 of which are believed to be endemic to Chile. It includes the publication of a new combination, Gavilea feuilleana comb. nov.   © 2003 The Linnean Society of London, Botanical Journal of the Linnean Society , 2003, 143 , 449−451.  相似文献

There are 20 Bellevalia species in Turkey, half of which are endemic. Chromosome numbers are known for 15 species. A chromosome survey of 145 Bellevalia individuals showed that the karyotype is remarkably stable. All are based on x  = 4. The majority are diploid with 2 n  = 8, but there is also a polyploid series of 2 n  = 16, 24 and 32. Aneuploidy occurs only at the octoploid level. Eleven individuals had metacentric B chromosomes, one had acrocentric Bs and one had telocentric Bs. Bellevalia pycnantha and B. paradoxa are morphologically similar, with B. pycnantha reduced to a synonom of B. paradoxa .  © 2003 The Linnean Society of London, Botanical Journal of the Linnean Society , 2003, 143 , 87–98.  相似文献

A distribution map of the new species and its related taxon is given.  © 2004 The Linnean Society of London, Botanical Journal of the Linnean Society , 2004, 146 , 251–255.  相似文献

The six-eyed pholcid spiders of East Africa are revised. A new genus is recognized, Buitinga n. gen ., with 17 new species and three species transferred from Spermophora Hentz. The new genus is characterized by the presence of a scape on the epigynum. This scape may be straight or tightly curled up at rest, and is usually highly expandable. Seven additional African and Comoran species are newly described and tentatively assigned to Spermophora . A data matrix with 60 characters and 77 taxa (including 20 East African species and 25 additional Spermophora and ' Spermophora -like' species) is analysed cladistically. Buitinga is closer to the genera Paramicromerys Millot (endemic in Madagascar) and Spermophorides Wunderlich (Mediterranean and Canary Islands) as well as to several African and Comoran species tentatively assigned to Spermophora than to the type species of Spermophora . It is argued that current estimates of species numbers may be inaccurate and that pholcids may turn out to be one of the most diverse spider families.  © 2003 The Linnean Society of London.

The species of Goniothalamus (Annonaceae) occurring in Peninsular Malaysia and Singapore are revised, updating the previous taxonomic treatment by James Sinclair, published in 1955. A total of 18 species is recognized, including a new species, G. tomentosus . Collections referrable to G. tomentosus were previously determined as ' G. marcanii '; examination of the types of G. marcanii reveals that the two taxa are not conspecific, however, and a new name is accordingly validated here. Goniothalamus tomentosus has closest affinities with the Javan/Sumatran species G. costulatus . Other important nomenclatural changes include the reduction of G. umbrosus to synonymy with G. tapis .  © 2003 The Linnean Society of London, Botanical Journal of the Linnean Society, 2003, 142 , 321−339.  相似文献

Molecular phylogeny of wood mice (Apodemus, Muridae) in East Asia   总被引:2,自引:0,他引:2  
Sequences of the mitochondrial cytochrome b (1140 bp) and nuclear IRBP (1152 bp) genes were used to assess the evolutionary history of Apodemus , using the complete set of Asian species. Our results indicate that speciation in Asia involved three radiations, which supports an earlier study. The initial radiation yielded A. argenteus (Japanese endemic), A. gurkha (Nepalese endemic), and the ancestral lineage of the remaining Asian species. This lineage subsequently diverged into four groups: agrarius-chevrieri ( agrarius group), draco-latronum-semotus ( draco group), A. peninsulae , and A. speciosus (Japanese endemic). The final step consisted of divergence within two species groups as a consequence of the geography of the Yunnan-Guizhou plateau and Taiwan. The ecological ability of two Apodemus species to inhabit one locality via niche partitioning likely drove the second radiation and shaped the basic geographical pattern seen today: A. argenteus and A. speciosus in Japan, A. agrarius and A. peninsulae in northern China, and the A. agrarius and A. draco groups in southern China. The three radiations are estimated to have occurred 7.5, 6.6, and 1.8–0.8 Mya respectively, using the IRBP clock, based on rat–mouse divergence 12 Mya.  © 2003 The Linnean Society of London, Biological Journal of the Linnean Society , 2003, 80 , 469–481.  相似文献

Following a revision of Thapsia (Apiaceae) in north-western Africa, the name Thapsia platycarpa is resurrected and lectotypified for a species that grows between Algeria and Morocco, and a new species Thapsia cinerea is described from the Rif region of north-eastern Morocco. Morphological features that differentiate between these and other species ( T. villosa , T. garganica , T. transtagana and T. gymnesica ) are discussed. An identification key for the plants of the area is presented.  © 2003 The Linnean Society of London, Botanical Journal of the Linnean Society , 2003, 143 , 433–442.  相似文献
