兰科一新属和新亚族——丫瓣兰属和丫瓣兰亚族

基于丫瓣兰Ypsilorchis fissipetala (Finet)Z.J.Liu,S.C.Chen &L.J.Chen(基名为裂瓣羊耳蒜Liparis fissipetala Finet)建立了兰科新属--丫瓣兰属Ypsilorchis Z.J.Liu,S.C.Chen&.J.Chen.新属与羊耳蒜属Liparis的区别点为:新属有两个粉蜡质花粉团:每个花粉团具1个多少有弹性的花粉团柄;花瓣二深裂;叶具强烈波状的边缘,其先端有一个长达1 mm的芒尖.这些特征表明了其与羊耳蒜亚族Liparidinae有明显的差别,为此,建立了一个新的亚族--丫瓣兰亚族Ypsilorchidinae Z.J.Liu,S.C.Chen &L.J.Chert.     

Ypsilorchis and Ypsilorchidinae,a new genus and a new subtribe of Orchidaceae

A new orchid genus, Ypsilorchis Z. J. Liu, S. C. Chen & L. J. Chen, is established based on Ypsilor-chis fissipetala (Finet) Z. J. Liu, S. C. Chen & L. J. Chen (basionym: Liparis fissipetala Finet). The new genus differs from Liparis and its allies by having two granular-waxy pollinia each with a somewhat elastic caudicle, deeply bilobed petals and strongly crisped-margined leaves with an apical awn to 1 mm long. These features are an indication of its distant relation to the members of the subtribe Liparidinae, and thus a new subtribe, Ypsilor-chidinae Z. J. Liu, S. C. Chen & L. J. Chen, is proposed.

Singchia and Gunnaria, two new genera of Orchidaceae

Singchia Z. J. Liu ＆ L. J. Chen, a new orchid genus, is established based on the new species S. malipoensis Z. J. Liu ＆ L. J. Chen found in southeast Yunnan, China. The new genus is related to Pteroceras, from which it differs by having a lip with its basal margins immovably adnate to the lower part of the pendent column foot, a thin-walled spur, and very unequally and deeply split pollinia, each with a distinct caudicle. In addition to a discussion on Ascocentrum pusillum, a species of questionable placement, another new genus, namely Gunnaria S. C. Chen ex Z. J. Liu ＆ L. J. Chen, is set up and a new combination, namely G. pusilla （Aver.） Z. J. Liu ＆ L. J. Chen, is made. The new genus Gunnaria differs from its allyAscocentrum by having a cross-shaped pollinarium, sulcate or split pollinia, each with a distinct caudicle attached to a common linear stipe much longer than either pollinia or viscidium, and strongly incurved side lobes of the lip.
