中国西南特有木兰科植物石山木莲的修订(英文)

Notes on Manglietia aromatica var. calcarea( Magnoliaceae),a Variety Endemic to South-Western China

石山木莲Manglietia aromatica var.calcarea(X.H.Song)Sima et S.G.Lu为中国西南部特有植物,仅分布于贵州和广西,过去一直被忽视或作为木莲M.fordiana Oliver的变种。通过与木莲和香木莲M.aromatica Dandy的性状比较表明,它是一个好而明确的类群,与香木莲近缘而与木莲远缘。文中将其作为香木莲的变种,并重新组合命名为M.aromatica var.calcarea(X.H.Song)Sima et S.G.Lu。
