印度的三種懸鉤子屬新紀錄種（薔薇科）

Three New Recorded species of Rubus L. (Rosaceae) from India

本文首次報導了庫氏懸鉤子（新擬中名）、多齒懸鉤子與五葉懸鉤子在印度發現的新分佈紀錄。庫氏懸鉤子的托葉掌狀且裂片不規則鋸齒緣。多齒懸鉤子與某些屬於矮生莓節的匍匐性物種如齒萼懸鉤子、梳齒懸鉤子及刺萼寒莓相似，但其花瓣粉紅色，葉先端尖至鈍形而非圓形。五葉懸鉤子則可從近無柄的小葉、葉兩面沿脈被毛以及頂生單花等特徵輕易地與它種辨別。

Rubus cooperi D.G. Long, R. polyodontus Hand.-Mazz., R. quinquefoliolatus T.T. Yu & L.T. Lu, are reported first time from India. Rubus cooperi is characterized by the palmate stipules with lacinate margins. Rubus polyodontus shows some morphological closeness with other prostrate species of sect. Chamaebatus Focke, viz. R. calycinus Wall.ex D. Don, R. pectinaris Focke and R. pectinellus Maxim., but differs in having pink petals and acute to obtuse leaf apex. Rubus quinquefoliolatus can be easily recognized by its subsessile leaflets, hairs along veins on both surfaces and solitary terminal flowers which are always emarged from new shoots.
