东北罂粟属植物的分类

REVISION OF THE CLASSIFICATION OF PAPAVER FROM NORTH-EAST CHINA

本文对东北罂粟属植物的分类及其中的问题进行了讨论,并提出了一些新的见解,其中主要的是扩大了野罂粟(Papaver nudicaule.L.)(sensu ampl.),基本型分类性状的含义,缩小了应看做是其亚种的黑水罂粟(P.nudicaule L.subsp.amurense N.Busch.的分类性状含义,发现并提出了两个新的变种,即光果野罂粟P.undicaule L.var.glabricarpum P.Y.Fu及毛果黑水罂粟P.nudicaule L.subsp.amurenseN.Busch.var.seticarpum P.Y.Fu,同时提出了包括种下分类群的便于鉴别的东北罂粟属植物分类检索表。

The classification of the Papaver species from North-east China wasrevised. The concept of classificatory features of the basic form of thespecies, P. nudicaule L., was expanded—sensu ampl., including those planstswho have yellow, pale-yellow and orange flowers. The concept of the sup-species, P. nudicaule L. subsp. amurense N. Busch., was narrowed—sensustr., only refering to the plants with white flower and glabrous fruit.Those plants who have orange flower were classified into the subsp. nudi-caule. Two new varieties of the species were described, var. glabricarpumand subsp. amurense N. Busch. var. seticarpum. The new key to the genusspecies from North-east China was made.
