摘 要 ：尖突紫堇组（Sect．Mucroniferae Fedde）是青藏高原及喜马拉雅地区特有的高山类群。分布中心在北纬28-32度，东经88-96度之间，除短喙黄堇（C．brevirostrata C.Y.Wu et T．Y．Shu）生长在海拔3600米的林间草甸外，全部种类生长在4000—5400米的高原荒漠、流石滩、砂砾地或河滩上。在高海拔低纬度的自然条件下，它们共同发育了适应干寒和强辐射的特性。本组植物为具主根垫状高山草本，叶柄宽展，叶片1一3回羽状全裂，末回裂片椭圆形或匙形，通常具短尖。总状花序短缩，花少而直立着生，多少呈伞房状排列，除花冠上部外，大部为苞片所复盖。苞片大，扇形多裂或叶状具柄，裂片顶端常具有短尖或刚毛。蒴果椭圆形，成熟时通常下弯而隐藏于苞片之中。全组11种，2变种，除尼泊尔产的大萼黄堇（C.megacalyx Ludlow）和棒苞黄堇（C．clavibracteata Ludlow）外，全部种类青藏高原均有分布。
Abstract:Sect. Mucroniferae Fedde is an endemic alpine group of the Genus Corydalis Vent.in Qinghai-Xizang plateau and Himalayas. The center of the distribution of this Section is between 28-32℃ N. 88-96°E. All species of this section, except C.brevirostrata C.Y.Wu et T.Y.Shu distributing merely up to 3600 m. altitude in the forest meadows, dwell in the plateau-desert, alpine scree, gravel or river banks up to 4000-5400 m. altitude. They had in common developed the specific characters adapting dryness and coolness under the natural condition of high altitude and low latitude. They are the cushion-like alpine herbs which possess taproot, leaves with flattened petio1e, 1-3 pinnatisect. The ultimate lobules of leaves elliptic or spathulate are often mucronated.
