The material of Micromeria s.s. ( M. sect. Micromeria ) from tropical to southern Africa and the Arabian Peninsula is revised. The endemic Ethiopian M. unguentaria Schweinf. is retained as a species, while the other African and Arabian material of Micromeria is included in M. imbricata (Forssk.) C. Chr. M. imbricata is divided into the following three varieties: var. imbricata , which is very polymorphic, widespread in the African highlands, and also occurs in Arabia; var. rhodesiaca (Elly Walther & K.H. Walther) Ryding, which occurs in the highlands of Malawi, Mozambique and Zimbabwe; and var. villosa (Elly Walther & K.H. Walther) Ryding, which occurs in montane to alpine areas of Ethiopia and East Africa. Discontinuities in the variation within var. imbricata , observed at some localities, are suggested to be a result of partial autogamy. Problems with delimitation between M. imbricata , the East Asiatic M. biflora (Buch.-Ham. ex D.Don) Benth. and some Mediterranean species are discussed. © 2007 The Linnean Society of London, Botanical Journal of the Linnean Society , 2007, 155 , 427–446. 相似文献

A synopsis of Goniothalamus species (Annonaceae) in Thailand, with descriptions of three new species
RICHARD M. K. SAUNDERS PIYA CHALERMGLIN 《Botanical journal of the Linnean Society. Linnean Society of London》2008,156(3):355-384
A comprehensive taxonomic revision of Goniothalamus species (Annonaceae) occurring in Thailand is presented for the first time. Twenty-five species are recognized, including three that are described as new to science ( Goniothalamus aurantiacus from South-Western Thailand, Goniothalamus maewongensis from Northern Thailand, and Goniothalamus rongklanus from Northern and North-Eastern Thailand). Several taxonomic and nomenclatural misunderstandings are corrected. The name G. griffithii is shown to be widely misapplied for populations in Northern Thailand, for which the name G. calvicarpus should be applied; 'true' G. griffithii is restricted to South-Western Thailand and Myanmar. In addition, the widely used name G. marcanii is shown to be a synonym of G. tamirensis , and the name G. latestigma , previously regarded as a synonym of G. undulatus , is reinstated. Goniothalamus cheliensis is furthermore newly recorded from Thailand. Most species are restricted to Peninsular Thailand and represent a Malesian floristic component. © 2008 The Linnean Society of London, Botanical Journal of the Linnean Society , 2008, 156 , 355–384. 相似文献

Ornithogalum chetikianum Uysal, Ertugrul & Dural sp. nov. (Liliaceae) is described and illustrated from Anatolia, Turkey. The species grows on alpine steppe and stony places in Bozkır (C4 Konya province) in South Anatolia. It is closely related to O. nutans L. and O. demirizianum Malyer & M.Koyuncu, an endemic confined to South Anatolia. Diagnostic morphological characters are discussed. Notes are also presented on the ecology, biogeography and conservation status of the new species. © 2005 The Linnean Society of London, Botanical Journal of the Linnean Society , 2005, 148 , 501–504. 相似文献

As part of a recent revision of the genus Crambe , based on the morphological study of herbarium and cultivated material, the systematics of section Dendrocrambe DC. are reviewed here. Section Dendrocrambe (including monospecific section Rhipocrambe Svent.) is considered to comprise 14 species, all endemic to Macaronesian archipelagoes: 13 in the Canary Islands and one in the Madeira Islands. Crambe feuilleei A. Santos and C. gomerae subsp. hirsuta Prina are described here, C. fruticosa subsp. pinnatifida (Lowe) Prina & Mart.-Laborde is proposed as a new status, and a key for the identification of all taxa, as well as maps with localities of collection, are provided. © 2008 The Linnean Society of London, Botanical Journal of the Linnean Society, 2008, 156 , 291–304. 相似文献

The species formerly recognized as Teucrium scorodonia in Madeira is here described as new: Teucrium francoi M. Seq., Capelo, J.C. Costa & R. Jardim. Morphologically close to species of Teucrium gr. scorodonia [ T. scorodonia L., T. pseudoscorodonia Desf., T. siculum (Raf.) Guss. and T. kotschyanum Poech], it exhibits, nonetheless, some distinct diagnostic characters. The indumentum density and type of hairs of T. francoi are clearly distinct from those of related species, as are the shape and dimensions of the leaves and bracts, calyx, and corolla, which are all taken as taxonomically significant diagnostic features. A diagnosis and a distribution map are presented for this new species. Morphology, ecology, biogeography, and conservation issues are discussed. Teucrium francoi , which is an endemic from Madeira (Portugal), is to be found mostly in the scope of the association Teucrio francoi–Origanetum virentis J.C. Costa, Capelo, Jardim, Sequeira, Lousã & Rivas-Martínez, but also occurs in somewhat humid habitats, such as open stands of Rosa mandonii Déségl. associated with small streams. © 2008 The Linnean Society of London, Botanical Journal of the Linnean Society , 2008, 156 , 639–647. 相似文献

Tahina J.Dransf. & Rakotoarinivo, gen. nov. (Arecaceae) is described as a new genus from north-western Madagascar, with a single species T. spectabilis J.Dransf. & Rakotoarinivo, sp. nov. Tahina is included within tribe Chuniophoeniceae of subfamily Coryphoideae, based on the strictly tubular imbricate rachilla bracts, the flowers grouped in cincinni with tubular bracteoles, and the stalk-like base to the corolla. This position is corroborated by evidence from plastid DNA. Lamina anatomy is discussed in detail, and similarities with and differences from the other members of Chuniophoeniceae are discussed. Based on the ecological characteristics of the single locality, predictions are made on where else it may occur in Madagascar. © 2008 The Linnean Society of London, Botanical Journal of the Linnean Society , 2008, 156 , 79–91. 相似文献

Hieracium petrovae Vladimirov & Szeląg sp. nov. , a new diploid (2 n = 18) species in H. sect. Pannosa Zahn, is described and illustrated from the Rhodope Mountains, South Bulgaria, and compared with related taxa. It grows in relict habitats in crevices of limestone rock together with many Balkan endemics. H. petrovae is morphologically similar to taxa from the H. pannosum , H. pilosissimum and H. heldreichii groups (collective species sensu Zahn) to some of which it is a presumed ancestral species. © 2006 The Linnean Society of London, Botanical Journal of the Linnean Society , 2006, 150 , 261–265. 相似文献

The southern African pholcid spiders previously assigned to Pholcus and Spermophora are revised and their phylogenetic position within Pholcidae is analysed cladistically. Two distinct groups are recognized: the first is restricted to the Cape region and probably correctly placed in Spermophora ; it includes Spermophora peninsulae Lawrence and four new species. The second is more widely distributed in southern and eastern South Africa, and reaches as far north as Cameroon, Congo (Democratic Republic) and Uganda; it is assigned generic status ( Quamtana gen. nov .), and includes two species transferred from Pholcus [ Q. leptopholcica (Strand), Q. ciliata (Lawrence)] as well as 23 new species. A key to the pholcid spiders of South Africa is presented. A close correlation between a male character (distance between cheliceral apophyses) and a female character (distance between pockets on epigynum) is documented in Quamtana . © 2003 The Linnean Society of London, Zoological Journal of the Linnean Society, 2003, 139 , 477−527. 相似文献
