Impatiens tripetala (Balsaminaceae), a new record species of Impatiens from China

  • 摘要: 报道了产自中国云南的凤仙花属一新记录种:三瓣凤仙花(Impatiens tripetala Roxb.ex DC.)。该种原产于孟加拉国和印度,本次在中国为首次发现。该种与缅甸凤仙花(I.aureliana Hook.f.)外形相似,但前者花单生或簇生,唇瓣囊状,深10~17 mm,距长5.5~8 mm,蒴果光滑,以此与后者相区别。凭证标本存放于湖南师范大学植物标本馆(HNNU)。

     

    Abstract: Impatiens tripetala Roxb. ex DC.is reported here as a new record species from China. It is already known from Bangladesh and India. This species is similar to I. aureliana Hook. f. in morphology, but differs from I. aureliana in flowers solitary or fascicled, lower sepal saccular, 10-17 mm deep, spur 5.5-8 mm long, and capsule glabrous. Voucher specimens are deposited in the Herbarium of Hunan Normal University (HNNU).
