摘要：

本文对国产棕榈藤3属21种茎的表皮组织进行了系统的比较观察，首次报道了棕榈藤茎表皮细

胞的排列式样，并结合表皮细胞类型和气孔、“反射体”的有无等特征，将国产棕榈藤茎的表皮组织划分

为3种类型3种亚型。(1)钩叶藤型:表皮细胞为长方形，细胞交错排列呈砖墙状。(2)黄藤型:表皮细

胞为不规则的四边形，细胞排列呈不规则网状，如龟背。(3)省藤型:A亚型，表皮细胞六边形，细胞排列

呈网状，气孔平列型或四轮列型；B亚型，表皮细胞四边形，细胞交错排列呈砖墙状，细胞长轴平行于茎

轴，气孔梭状四轮列型；C亚型，表皮细胞四边形，垂周壁呈波浪状，细胞交错排列如砖墙状，细胞的长轴.平行于茎轴。本文还讨论了棕榈藤茎表皮组织的特征及其在分类上的意义。

Abstract:

The stem epidermal characters of 21 species belonging to three genera (Calamus,

Daemonorops, Plectocomia) from China were investigated. The results show that the ar-

rangement of epidermal cells, stomatal types and occurrence of reflective body are of taxo-

nomic significance. Based on these features, epidermal cells of rattan stems can be divided

into three types and three subtypes. (1) Plectocomia-type: epidermal cells rectangle, wall-like

arranged; stomata tetracytic, found in P.himalayana Griff., P.microstachys Burret.

(2) Daemonorops-type: epidermal cells irregularly quadrilateral, net-like arranged; stomata

tetracytic, found in D. margaritae(Hance) Becc., D. jenkinsiana (Griff.) Mart. (3)

Calamus-type: Subtype A: epidermal cells hexagonal, net-like arranged; stomata tetracytic

or paracytic, found in C. henryanus Becc., C. tetradactylus Hance, C. viminalis Willd.

var. fasciculatus(Roxb.) Becc., C. flagellum Griff., C. gracilis Roxb., C. dioicus

Lour., C. melanoloma Mart., C. yunnanensis S. J. Pei et S. Y. Chen, C. nambariensis

Becc. var. yingjiangensis S. J. Pei et S. Y. Chen, C. multinervis Becc., C. nam-

bariensis Becc. var. xishuangbannaensis S. J. Pei et S. Y. Chen, C. balansaeanus Becc.

Subtype B: epidermal cells rectangle, wall-like arranged, with the long axes parallel to stem

axes; stomata shuttle tetracytic, found in C. australis Mart., C. bonianus Becc., C.

rhabdocladus Burret, C. compsostachys Burret. Subtype C: epidermal cells rectangle, anti-

clinal wall curved, wall-like arranged, with the long axes parallel to stem axes, found in C.

caryatoides Becc. In addition, the taxonomic implications of epidermal characters are dis-

cussed. It is possible to distinguish Calamus and Daemonorops by stem epidermal characters.
