Abstract

Abstract Radula deflexilobula Promma, L.N.Zhang et R.L.Zhu is described and illustrated as a new species from Thailand. This species is distinctive in 1) the presence of dimorphic leaf lobules that are subrhombic and strongly reflexed on pendulous shoots, subquadrate and not reflexed on creeping shoots; 2) leaf lobules covering the stem ca. 1/3–1/2 of the stem-width, not auriculate at base, and 3) leaf cells thin walled with indistinct trigones and smooth cell surface. Our phylogenetic analyses based on three chloroplast regions (trnG, trnL-F, atpB-rbcL) confirm that this new species belongs to subg. Radula and is sister to R. decurrens Mitt. known from Fiji.

摘要:本文报道了泰国一新种Radula deflexilobula Promma, zhang l.n et zhu r.l.l。本种在以下方面是独特的:1)二形叶小叶的存在，在下垂的芽上是近菱形的和强烈反折，在匍匐的芽上是近方形的和不反折;2)叶小叶覆盖茎，约占茎宽的1/3-1/2，基部不呈耳状;3)叶细胞薄壁，细胞表面光滑，三角形不明显。我们基于三个叶绿体区域(trnG, trl - f, atpB-rbcL)的系统发育分析证实了该新种属于亚g。拉杜拉和他的妹妹r·德科伦斯·米特。来自斐济。
