| 摘 要： | 在标本室研究和野外考察的基础上,对中国细柄茅属Ptilagrostis Griseb.几个类群进行了分类修订。双叉细柄茅P. dichotoma Keng ex Tzvelev和窄穗细柄茅P. junatovii Grub.分别被归并到细柄茅P. mongholica (Turcz. ex Trin.)和太白细柄茅P. concinna (Hook. f.) Roshev.中作异名;小花细柄茅P. dichotoma Keng ex Tzvelev var. roshevitsiana Tzvelev则被提升为种P. roshevitsiana (Tzvelev) L. B. Cai。

| Abstract: | Based on both herbarium and field observations, Ptilagrostis dichotoma Keng ex Tzvel. and P. junatovii Grub. are reduced to synonymy of P. mongholica (Turcz. ex Trin.) Griseb. and of P. concinna (Hook. f.) Roshev. Respectively, and a new combination, P. roshevitsiana (Tzvel.) L. B. Cai, is proposed. |
