摘 要 ：报导了从云南省金平县用种子（种子来源于越南莱州省的燕汤）繁殖的幼苗引入四川长宁县栽培的香竹属一新种越香竹(Chimonocalamus peregrinus Yi et L. S. Ma)。新种与马关香竹(Ch.makuanensis Hsueh et Yi)相近似［1,3~5］，但节间幼时微被灰粉，密被紫色小点，在分枝一侧中下部或基部扁平，并具纵脊和沟槽，无毛，刺状气生根较短，长约1~3 mm，箨鞘短于节间长度，无不同颜色的纵条纹，箨舌三角形、“山”字形或稀近于截平形，高1~2 mm，小枝具叶（4）6~8枚，叶鞘口繸毛2~4枚，长3~4 mm，叶片下面淡绿色；也近似角香竹(Ch.bicorniculatus S. F. Li et Z. P. Wang)［2,4,5］，不同在于节间无毛，在分枝一侧中下部或基部扁平，并具纵脊与沟槽，节上气生根刺离生，箨鞘顶端两侧低于或远低于中部，箨舌高1~2 mm，小枝具叶（4）6~8枚，叶片长8.5~13 cm，宽6~10 mm，次脉3（4）对，笋期在春季和秋季，易于区别。
Abstract:Chimonocalamus peregrinus Yi et L. S. Ma, a new species of the Bambusoidiae introduced from the Sichuan(Seed from Yen Tong of Lai Chau, Viet Nam), is described and illustrated.This new species is near Chimonocalamus makuanensis Hsueh et Yi［1,3~5］, but not the internodes green, glabrous, youngly a little farinaceous and densely covered violet pucticulate, cylindric or canaliculate and back in base or inferomedian of ramous side, glabrous, aerial root-spine shorter, 1~3 mm long, culm-sheathes shorter than interrnode, without colour stripe, ligule triangle, “W” form or rare truncate, 1~2 mm tall, leaves (4)6~8 per ultimate branch, oral setae 2~4, 3~4 mm long, blade lower surface pale green; it differs from Ch.bicorniculatus S. F. Li et Z. P. Wang by its shoot intiation in the spring and autumn［2,4,5］, glabrous internode, canaliculate and back in base or inferomedian of ramous side, aerial root separate, culm-sheathes shoulder even lower than middle, ligule 1~2 mm long, leaves (4) 6~8 per ultimate branch, blade 8.5~13 cm long, 6~10 mm broad, secondary veins 3(4)-paired.
