Abstract

SYAM, N., CHIKMAWATI, T. & RUSTIAMI, H. 2016. A phenetic study of the Calamus flabellatus complex (Palmae) in West Malesia. Reinwardtia 15(1): 27 - 41. — The number of species within the Calamus flabellatus complex is still under controversy because the taxonomic status of the species is not yet clear. Morphological observations were conducted on 119 collections of Calamus in the Herbarium Bogoriense (BO) and specimen images from the Singapore Herbarium (SING) and Kew Herbarium (K). The results showed that C. flabellatus complex (all species related to C. flabellatus) in West Malesia consisted of eight species and two varieties, i.e. C. acuminatus, C. amplijugus, C. congestiflorus, C. corrugatus, C. flabellatus, C. hypertrichosus, C. javensis, and C. ruvidus. They can be distinguished using several characters, i.e. leaf sheath, knee, ocrea, leaves, inflorescence, shape of fruit, number scale of fruit and seed. Calamus flabellatus var. laevibus and C. flabellatus var. congestispinosus are two new proposed varieties. Phenetic analysis of C. flabellatus complex in West Malesia divided all species into two major clusters with similarity coefficient of 46%.

马来西亚西部褐菖蒲群(棕榈科)的遗传学研究

SYAM，N.，CHIKMAWATI，T.&RUSTIAMI，H.2016。马列西亚扇形Calamus flabellatus复合体（棕榈科）的表型研究。Reinwardtia 15（1）：27-41.--扇形Calamus复合体中的物种数量仍存在争议，因为该物种的分类地位尚不清楚。对Bogoriense植物标本馆（BO）的119个Calamus标本和新加坡植物标本馆和邱植物标本馆的标本图像进行了形态学观察。结果表明，西马列西亚的扇形C.flabellatus复合体（所有与扇形C.flabellatus相关的物种）由八个种和两个变种组成，即渐尖C.acuminatus、扩大C.amplijugus、同源C.conustiflorus、波纹C.crumbus、扇形C.flabelatus、高毛C.hypertricosus、哈文西C.javensis和红毛C.ruvidus。它们可以通过叶鞘、膝盖、叶鞘、叶片、花序、果实形状、果实和种子的数量尺度等几个特征来区分。扇形Calamus flabellatus var.laevibus和扇形C.flabellatu var.conestispinosus是两个新品种。对西马列西亚扇形C.flabellatus复合体进行遗传分析，将所有物种划分为两个主要类群，相似系数为46%。
