Abstract Strobilanthes pseudocollina K. J. He & D. H. Qin, a new species of Acanthaceae
from Guangxi, China, is described and illustrated. It is similar to S. collina Nees, but differs
by leaf blade coriaceous, inflorescence glabrous, with a few flowers sparsely arranged.
Key words Strobilanthes, Strobilanthes pseudocollina K. J. He & D. H. Qin, Acanthaceae,
new species, Guangxi, China.
摘要 描述了广西马蓝属Strobilanthes一新种, 即阳朔马蓝S. pseudocollina K. J. He & D. H. Qin, 并描
绘了形态图。该新种与S. collina Nees近似, 但以叶革质, 花序无毛, 花少且排列稀疏而不同。

在整理广西中医药研究所收藏的爵床科Acanthaceae马蓝属Strobilanthes Bl.标本的过
程中, 发现采于广西阳朔县的一号标本——覃德海45996比较特殊, 但该标本只有果实,
没有花, 我们遂再去原产地采集其花标本。经认真比较研究, 确认该植物与该属的已知种
类(Nees, 1832; Bremekamp, 1944; Wood, 1994, 1995; 方鼎等, 1997; 胡嘉琪, 2002; Bennett
& Scotland, 2003; Wood & Scotland, 2003a, b; Wood et al., 2003; Deng et al, 2006)不同, 是
一新种。该新种分布于广西阳朔县石灰岩山地, 生长在一座独立的小山上。新种植株零
散分布于近山顶一带的疏林中, 数量稀少。

阳朔马蓝分布于广西桂林市阳朔县, 该地为典型的喀斯特岩溶地貌, 群峰林立。该植
物生长于一座独立的石灰岩山上, 山四周是农田和旱地, 山上植被为次生阔叶林, 较为
茂密, 阳朔马蓝零散分布于山的上部, 生于灌木和杂草之间, 生长状况尚好, 能正常开花
结果 , 但植株数量不多 , 应当加以有效保护。主要伴生植物有 : 石山巴豆Croton
euryphyllus W. W. Smith.、红背山麻杆Alchornea trewioides (Benth.) Muell.-Arg.、龙须藤
