报道了中国兰科(Orchidaceae)隔距兰属(Cleisostoma Blume)一新记录种:角唇隔距兰(C.tricornutum Averyanov)。该种与C.crochetii(Guillaumin)Garay、C.parishii(J.D.Hooker)Garay相近,因其有不分枝的线状花粉团柄、球状的花粉团块和一个先端短喙状的半球形药帽而与C.crochetii(Guillaumin)Garay相区别;因其有松散、罕分枝的花序,长角状的唇瓣侧裂片而与C.parishii(J.D.Hooker)Garay相区别。提供了新记录种的形态描述及图片。 相似文献

鼠尾草属是唇形科中最大的属,全球有近1 000种。我国是鼠尾草属东亚分布中心,有84种,分布于全国各地,尤以西南地区最多。鼠尾草属植物具有很高的经济价值和观赏价值,但由于鼠尾草属植物分布广、种类多、形态变异大,给该属鉴定和分类学研究带来了很大的困难。此外,在采集和调查过程中发现弧隔鼠尾草亚属和荔枝草亚属的很多种类在营养生长期仅通过叶片很难鉴定。表皮毛是植物叶片上最常见的附属物,其分布特性和形态特征常作为植物鉴定和分类学研究的重要手段。该文利用光学显微镜和环境扫描电镜对18种和1变型共19份鼠尾草属植物的叶片类型、表皮细胞形状、垂周壁样式、气孔器类型和表皮毛等叶表皮微形态特征进行了观察和比较研究,为鼠尾草属的分类界定研究提供证据。结果表明:这19份鼠尾草属植物叶表皮和表皮毛形态特征在电子显微镜下表现出明显的多样性,叶表皮细胞形状为不规则形或多边形,垂周壁多数为浅波状或波状,少数为平直或弓形。气孔器为无规则型和不等细胞型,其中无规则型最为常见。样品叶表皮毛分为4个类型,盾状腺毛、头状腺毛、短非腺毛和长非腺毛。该属植物叶表皮的这些微形态特征,可为本属鉴定和分类学研究提供理论依据。 相似文献

Four new species of Orchidaceae from China, Heminium lijiangense, Peristylus fasciculatus, Platanthera milinensis, and Ponerorchis gongshanensis, together with a new country record, Peristylus tenuicallus, are described and illustrated based on morphological and/or phylogenetic analyses. Heminium lijiangense is closely related to H. elisabethae but differs from it by having the dorsal sepal ovate-orbicular and lip mid-lobe distinctly shorter than lateral lobes. P. fasciculatus is close to Peristylus tradescantifolius but is distinguished from it by having several fascicled and straight, root-like tubers (vs. one or two oblongoid tubers), old stems usually persistent, middle lobe of lip narrowly ligulate-lanceolate and half as long as the lateral lobes (vs. middle lobe deltoid, about a third as long as the lateral lobes or less), a raised callus at the base of each lateral lobe (vs. callus absent), spur gradually attenuate toward the apex (vs. spur clavate). Platanthera milinensis is similar to P. stenochila by sharing small green flowers and lip without a spur, but differs in having a creeping rhizome, a corymbose inflorescence, and a broadly ovate and slightly 3-lobed lip. Ponerochis gongshanensis is similar to P. faberi in its small flowers, but differs in having a linear leaf c. 3 mm wide (vs. leaf 5–13 mm wide), in the lip having collar-like raised margins on the sides of the spur entrance, and a mid-lobe which is notched at the apex but not divided into two divergent lobules that are nearly as large as the lateral lobes, as in P. faberi. All the proposed species obtained high support in phylogenetic analysis as new species. The recently described genus Apetalanthe is reduced to synonymy of Ponerorchis and a new combination is made. 相似文献
