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.
