报道中国茜草科(Rubiaceae)玉叶金花属一新记录种——长瓣玉叶金花(Mussaenda longipetala H. L. Li)。该种在形态上与尾裂玉叶金花(M. caudatiloba D. Fang)和狭瓣玉叶金花(M. lancipetal X. F. Deng & D. X. Zhang)相似,但区别在于叶片长圆状卵形或椭圆状卵形,托叶早落,正常的萼裂片长6~8 mm,花冠管长约3 cm,裂片披针形,长约12 mm。目前仅知分布于越南北部的广宁省和中国的广西北部湾沿海地区。凭证标本存放于广西植物标本馆(IBK)。  相似文献

通过对茜草科玉叶金花属植物玉叶金花传粉生物学及种内形态分化和分布特点的初步研究,发现该种的两个变种玉叶金花和白花玉叶金花在形态和生境适应上都有一定的规律。研究表明,楠藤与开黄花的玉叶金花原变种的传粉者主要是鳞翅目昆虫,而玉叶金花的白花变种的有效传粉者是膜翅目昆虫。认为变种白花玉叶金花居群的出现与同属植物楠藤的同域分布及避免相互竞争传粉者有关。白花玉叶金花变种的出现属于性状置换现象。  相似文献

粉花玉叶金花(Mussaendahybrida)为茜草科玉叶金花属植物。其独特的粉红色叶状萼、较大型的花序和长达半年的花期使之成为一种值得推介的观赏花卉。将它盆栽或在庭园种植都很适宜。但目前,我国只能在一些科研单位见到它的踪影,有待进一步普及、推广。粉花玉叶金花由国外引进,最早是在东南亚一些国家栽培,以菲律宾,新加坡和台湾等地种植较多。据称它是由同属原产非洲的红纸扇(M.erythrophylla)与另一种(M.philippica)的杂交后代中选育出的一个品种。其特别之处在于其5枚萼片都扩大成…  相似文献

金花蛇Chrysopelea ornata属游蛇科Colubridae游蛇亚科Colubrinae金花蛇属,在我国仅有一种。一百多年前Bottger(1888)在香港发现此蛇标本;Stanley(1914)报道福建有金花蛇分布,但地点不确切〔1,4〕;杨大同等(1983)报道在云南永德县有金花蛇分布〔2,3〕,但未见有形态和生态的描述;赵尔宓等(1990)根据苏联科学院动物研究所1888年由德国人Herz在海南岛采到1号雄性幼体标本,报道了该省金花蛇新纪录,并对它的形态作了描述〔1〕,这是中国境内所采金花蛇产地确切的报道。可见金花蛇在我国是十分罕见的。1985年7月28日,作者在云南省西双版纳勐腊县…  相似文献

Mussaenda lancipetala X. F. Deng & D. X. Zhang, a new species of Rubiaceae from Yunnan Province, Southwestern China, is described and illustrated. The new species is characterized by its reverse herkogamous sexual system, its ovate-lanceolate corolla lobes with caudate apex, and corolla tube covered with sparse farinose pubescence, by which it is clearly distinguished from other species of Mussaenda.  相似文献

Mussaenda yunnanensis, a new dioecious species of Rubiaceae from Yunnan Province, China, is described and illustrated. The new species can be recognized by its slender stem, congested‐cymose inflorescences and long corolla tubes. Differences between M. yunnanensis and two morphologically similar species (M. pubescens and M. antiloga) are presented. We also provide a key to all dioecious species of Mussaenda in China. The delimitation of the new species is further supported by molecular phylogenetic analyses based on eight plastid loci.  相似文献

Two new species of Mussaenda (Rubiaceae) from Aklan, Panay, Philippines are described and illustrated. Mussaenda ustii sp. nov. is distinct by its long pedicel (up to 7 mm), yellow with white margins corolla lobes forming a star and recurved stigma lobes which are always semi‐ or distinctly exserted in long‐styled morphs. Mussaenda viridiflora sp. nov. is characterized by its white, sweet‐scented corolla lobes, which are green tinged on the median ridges and bases, and strongly reflexed calyx lobes. A discussion of the relationships of the new taxa to closely related Philippine Mussaenda is provided. © 2008 The Linnean Society of London, Botanical Journal of the Linnean Society, 2008, 158 , 87–92.  相似文献

Roscoea cangshanensis M. H. Luo, X. F. Gao & H. H. Lin, a new species of the Zingiberaceae from Yunnan, China, is described and illustrated. The new species is related to R. forrestii Cowley in habit, but differs in having 2-lobed labellum, each lobe 2-lobulate, base narrowed to a stalk with white lines, and narrower leaf blade, (2–)7–24×1.5–2.5 cm, with base narrow to petiole-like. The new species is also similar to R. debilis Gagnep. in having leaf base narrow to petiole-like, labellum obovate-cuneate, 2.5–3.5×2.5–3.0 cm, with white lines at throat, but differs in having bracts non-tubular, shorter, 5–15 mm long, concealed in leaf sheaths, corolla tubes longer, 10–12.5 cm long, labellum 2-lobed with each lobe further 2-lobulate.  相似文献
