Abstract
new species of the genus Lycium L. , L. parvifolium and a new variety L. barbarian var. implicatum were described from Zhongning.Ningxia Province, western China. L. parvi folium was closely related to L. barbarum but differs from the latter by the branches zigzag,leaves comparatively small, 1 - 2. 5( - 3)cm long.1. 5 -2( - 3)mm wide,flowers 1 - 2,fasciculate on short-branches with leaves,calyx cupular or tubular,stamens inserted at the throat of corolla tube,filaments along with corolla glabrous or sparsely pubescent;berry usually pale yellow,nearly translucent ,compressed-globose or ellipsoidal,6 -10 mm×6 - 8 mm,seeds 5 - 8. L. parvifolium was also closed to L. dasystemum and L. turcamanicum,but in the latter two species,the branches not zigzag,flowers usually 2 - 3 or more fasciculate on short-branches with leaves,corolla tube about 2 times as long as limb and lobes,stamens inserted at the nearly middle of corolla tube,berry usually red. Especially,in L. turcomanicum,calyx widely bell-shaped,usually 4-5-lobed, corolla lobes sparsely ciliate at margin. L. barbarum var. implicatum differed from L. barbarum by the branches many and densely arranged,leaves comparatively small,1 - 1. 8 cm long,l. 5 -2. 5 mm wide;stamens inserted at the throat of corolla tube,unequal in length,two of them shorter,the others longer,berry pale purple,nearly transparent, ovoid or elliptical, 5 - 8 mm long,3 -6 mm in diam. ,sweet,seeds 2- 4.关键词
