| Abstract: | Two species of the genus Delphinium(Ranunculaceae), D. breviscaposum W. T. Wang and D. filibracteolum W. T. Wang, are described as new from northwestern Yunnan Province. Of them, D. breviscaposum W. T. Wang is related to D. chayuense W. T. Wang, differing in three fasciculate short scapes, glabrous raceme rachis and pedicels, longer bracteoles, smaller sepals and undivided staminode limbs. And D. filibracteolum W. T. Wang is related to D. dolichocentroides W. T. Wang,differing in its flower in panicles,shorter pedicels, sepals and spurs, not appendiculate staminode claws, and glabrous carpels. |
