本文报道了兰科一新属- J. Liu，S. C. Chen & L. J. Chen，以裂瓣叶蕨Ypsilopsis fissipetala（Finet）Z. J. Liu，S. C. Chen & L.（学名：Liparis fissipetala Finet）。该新属与羊耳蒜属及其近缘属的区别在于具有两个颗粒状蜡质花粉块，每个花粉块具有有点弹性的茎部，深二裂的花瓣和强烈卷曲边缘的叶，顶端芒长达1毫米。这些特征表明它与脂鲤亚科的成员有较远的亲缘关系，因此有一个新的亚族，即脂鲤亚科Z。J. Liu，S. C. Chen & L. J. Chen建议。
A new orchid genus, Ypsilorchis Z. J. Liu, S. C. Chen & L. J. Chen, is established based on Ypsilorchis 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, Ypsilorchidinae Z. J. Liu, S. C. Chen & L. J. Chen, is proposed.
