查询词典 taxon

To summarize molecular, morphology, chromosome and pollen characters, the conclusion was reached that Epimedium was an nd monophyletic taxon. To divide the genus into any groups would be artificial. It is proposed that the disjunction by space, climate and seas were the main reason of respectively differentiation of each group by the view of geographic and climate changes in the temperate zone of the world. Because of its evolution-conservation, the disjunction did not bring about obvious divergence on the level of molecular and morphology.

综合分子特征和形态、细胞学、孢粉学等性状，提出淫羊藿属是一个进化上极为保守的、自然的单系的植物类群，进行属下任何阶元的划分都将是人为的，从旧世界温带的地质变化及气候变迁的角度推测，空间、气候和海洋的隔离是产生类群各自分化的主要原因，但由于其进化上极度保守，这些隔离尚未产生出类群间形态上和分子水平上的明显趋异。

It is, therefore, proposed that the organisms be classified in this taxon as Nocardia miyunensis sp. nov. and Nocardia jiangxiensis sp.
