短梗千金藤,越南防己科新记录种（英文）
|
摘要
报道了越南防己科(Menispermaceae)一新记录种:短梗千金藤(Stephania brevipes Craib)。据文献记载,该种仅分布于泰国,现首次在越南发现其分布。本种与粪箕笃(S. longa Lour.)形态相近,但叶宽三角状卵形至三角状扁圆形,雄花序小,腋生或生于无叶的茎上,总梗较短,花萼淡黄色,花瓣红紫色,内果皮外部沟数目较少而与后者不同。还提供了该种详细的形态学描述、图版、分布及生态学等信息。凭证标本保存在越南国立自然博物馆标本馆(VNMN)和中国科学院华南植物园标本馆(IBSC)。
Stephania brevipes Craib(Menispermaceae), previously known only from Thailand is reported from Vietnam for the first time. It is morphologically allied to S. longa Lour., but differs in having broadly triangular-ovate to triangular-oblate leaves, a small male inflorescence axillary or on leafless stems with shorter peduncle, yellowish sepals, red-violet petals, and endocarps with fewer transverse ridges. A detailed morphological description, a line drawing and color plate as well as distribution and ecology information of this species are given. The vouchers are kept in the herbaria of Vietnam National Museum of Nature(VNMN) and South China Botanical Garden, Chinese Academy of Sciences(IBSC).
