摘要
描述了沙棘属 (H ippophae)一个分布于四川省汶县和茂县的新亚种——卧龙沙棘 (H.rhamnoidessubsp wolongensis Y. S. L ian,K. Sun & X. L . Chen)。依据主要形态特征和分布的分析 ,它近缘于中国沙棘 ,但是卧龙沙棘具有莲花瓣状着生的花芽 ,叶片大而互生、叶边缘呈明显地波状而且波谷常向背面稍反折 ,叶柄和果柄明显较长等 ,容易辨认。卧龙沙棘分布比较小 ,仅仅出现在四川省汶县和茂县海拨 16 6 0～ 192 0 m的山坡上。
In this paper, a new subspecies of Hippophae (Elaeagnaceae), H. rhamnoides subsp. wolongensis Y.S. Lian, K. Sun & X.L.Chen, from Sichuan Province, China is described and illustrated. According to analysis of the distribution and main characters, it is allied to H. rhamnoides subsp, sinensis Rousi but is distinct in having rosulately arranged flower buds, larger, alternate leaves with usually more of less sinuous margins, longer petioles, and longer peduncles. Hippophae rhamnoides subsp. wolongersis is rare and occurs only in Wenchuan and Mao Counties of Sichuan Province, at 1 660～1 920 m.
