摘要
本义引述了疆堇属(Roborowskia Batalin)自建立以来存在的不同意见。通过对实际材料的观察、解剖,对疆堇作了重新描述,纠正其重大特征的错误,在此基础上,确定疆堇不能独立为一个属,而是紫堇属的一个种,并建立紫堇属的一个新组—疆堇组。
There were two different views about the status of the monotytic genus Roborowskia Batalin, since it was established in 1893 based upon the Roborowski's collection from Kunlun mountain. As far as it has been treated as an endemic genus of China by some botanists without regard to the advices of Hutchinson (1921), Liden (1986), and so on. They had ever pointed out that it is perhaps not distinguishable from Corydalis and had better to be a section of Corydalis. Unfortunately they probably had no chance to see the specimens, as it too difficulty to find. It was said that it was rediscovered only once in 1940 except Roborowski did. Their opinion only based upon the Batalin's description and didn't have a effective correction, so they couldn't persuade some botanists to accept their point of view. This question puzzled all botanists till now, when he deals with the genus. It is just lately that we got enough topotype specimens to revise the genus. By looking into the specimens, we find that Batalin's description is unfair or even wrong. He wrote in his description that it is defferent from Corydalis by its woody at the base, the flower as solitary, the scapose without bracts, and the fruit with the style to fall together with one of the valves. In fact, it is ture of the woody base and falling pattern of the style described by Batalin, but the inflorescence with 2-4 flowers and with lanceolate bract under each flower. The flowers with a short saccate calcar and with two remarkable calyces which is about 7-8 mm long and 1 mm late. By the characters, it should be replaced into a section of Corydalis which relates to Seet.Strictae Fedde ex Wendelbo.Sect.Roborowskia (Batalin) H.Chuang et Z.Y.Su differs from Sect.Strictae by its pinnate leaves, larger bracts and calyx, subglobose capsules and unique stigma which is depress and shallow with smooth top, its lateral bases decurrent downward and near the style. Their distributional area is the same to.
