【摘要】 记载了棘豆属（ＯｘｙｔｒｏｐｉｓＤＣ．）一新组（Ｓｅｃｔ．ＯｃｈｒｏｃｅａＧ．Ｚ．Ｑｉａｎ）。目前该组包括二个种，它们是：黄穗棘豆（Ｏ．ｏｃｈｒａｎｔｈａＴｕｒｃｚ．）和绿黄棘豆（Ｏ．ｖｉｒｉｄｉｆｌａｖａＫｏｍ．）。过去，国内的学者都将黄毛棘豆（Ｏ．ｃｈｒｙｓｏｔｒｉｃｈａＦｒａｎｃｈ．）与黄穗棘豆等同，而文中作者认为黄毛棘豆是黄穗棘豆的一个变种。另外异色黄毛棘豆（Ｏ．ｏｃｈｒａｎｔｈａＴｕｒｃｚ．ｆ．ｄｉｖｅｒｓｉｃｏｌｏｒＨ．Ｃ．ＦｕｅｔＭａ）被作为变种处理。绿黄棘豆是一个中国新分布种。更多还原

【Abstract】 A section of the Genus Oxytropis DC. Sect. Ochrocea G. Z. Qian is recorded in this paper. At present, two species are included in this section. They are O. ochrantha Turcz. and O. viridiflava Kom.. In the past, O. chrysotricha Franch. was regarded as O. ochrantha Turcz. in works of Chinese scholars. The author pointed out that it should be a variety of O. ochrantha Turcz., and treated the forma O. ochrantha Turcz. f. diversicolor H. C. Fu et Ma as a variety. At last, the species O. viridiflava Kom. is a new distribution species in China.更多还原
