| 该文描述了自云南西北部发现的毛茛科翠雀花属二新种:短葶翠雀花(Delphinium breviscaposum W. T. Wang)和丝苞翠雀花(D. filibracteolum W. T. Wang)。短葶翠雀花与察隅翠雀花(D. chayuense W. T. Wang)在亲缘关系上相近,前者与后者的区别在于短葶翠雀花植株具3条簇生短花葶,总状花序的轴和花梗无毛,小苞片较长,萼片较小,退化雄蕊的瓣片不分裂; 丝苞翠雀花与拟长距翠雀花(D. dolichocentroides W. T. Wang)近缘,前者与后者的区别在于丝苞翠雀花的花组成圆锥花序,花梗、萼片和萼距均较短,退化雄蕊的爪无附属物,心皮无毛。 |

| 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. |
