摘要
描述了中国云南毛茛科Ranunculaceae一新种——哀牢山毛茛Ranunculus ailaoshanicus W.T.Wang。此种在体态上与圆裂毛茛R.dongrergensis Hand.-Mazz.极为相似,但以茎较低矮,无叶,花较小,花瓣较小,长圆状椭圆形,脉不明显而相区别。
Ranunculus ailaoshanicus W. T. Wang, a new species of the Ranunculaceae from Yunnan, China, is described and illustrated. This species in habit shows striking resemblance to Ranunculus dongrergensis Hand.-Mazz., and differs from the latter in its lower leafless scapes, smaller flowers, and smaller, oblong-elliptic petals with obscure nerves. In R. dongrergensis, the stems are 5-15 cm tall and bear cauline leaves, the flowers are larger, 1-1.8 cm in diam., and the petals are larger, obovate in outline, 4-9 mm long, 2.2-7 mm broad, and nervose.
