马鞭草科Verbenaceae紫珠属Callicarpa主产于亚洲热带和亚热带,我国种类较为丰富。报道了2个新组合:(1)秃红紫珠Callicarpa subglabra(C. P’ei)L. X. Ye et B. Y. Ding应作为独立的种,与红紫珠C. rubella Lindl.的区别在于除嫩枝疏被短柔毛外全体无毛,叶片纸质,倒卵状长圆形或狭椭圆形,中部大多明显收缩,基部圆形或浅心形,不呈耳垂状,边缘具锯齿,叶柄长4～6 mm;(2)钝齿红紫珠C. rubella var. crenata(C. P’ei)L. X. YeetB.Y.Ding作为变种处理,与红紫珠的区别在于全体密被有腺多节毛和无腺多节毛,叶片纸质,倒卵状披针形或倒披针形,中部明显收缩,基部心形,呈耳垂状,边缘具细钝锯齿。

Callicarpa L., belonging to Verbenaceae, distributes in tropical and subtropical regions, and China is rich in species diversity. Two new combinations of Callicarpa, C. subglabra (C. P'ei) L .X. Ye et B.Y. Ding and C. rubella var. crenata (C. P’ei) L. X. Ye et B.Y. Ding, are reported. Callicarpa subglabra differs from C. rubella in having plant glabrous with the exception of sparsely pubescent tent shoots, lamina paperous, obovate-oblong or narrowly elliptic, attenuate at middle, base rounded or slightly cordate, not auriculate, margin serrate, petioles 4 - 6 mm long. Callicarpa rubella var. crenata differs from C. rubella in having plant densely multicellular-glandular and multicellular-pilose, lamina paperous, obovate-lanceolate or oblanceolate, attenuate at middle, base cordate and auriculate, margin thinly obtuse-serrate.
