摘要

翼头蕨属(Caprifoliaceae)在全球共有30种,主要分布于北半球温带地区,其中伊朗报告有14种,其中特有种5种。利用光镜对11种伊朗翼头目15个样品的35个叶相关性状和30个柄相关性状进行了研究。结果表明,中脉有2种,叶被有6种,花序梗被有5种。除雨松和短叶松外,大多数种的叶片和花序梗均有草酸钙结晶。花梗的轮廓为六角形、圆形或椭圆形。维管柱的形状从圆形到波纹状不等。与其他种属相比,温德尔博伊在形态上有很大的不同,解剖上也表现出不同的特征。研究发现,加勒曼和库尔迪乌的花梗六角形剖面与两种szovitsii的花梗非常相似。然而,上述性状被发现对其他物种的信息或特征较少。综上所述,叶和花序梗的解剖特征可能对翼头属某些种的鉴别具有一定的分类意义。

Leaf and peduncle anatomy of some species of the genus Pterocephalus (Caprifoliaceae) from Iran
Pterocephalus (Caprifoliaceae) consists of 30 species worldwide, mainly distributed in the temperate regions of the northern hemisphere, of which 14 species were reported from Iran, including five endemic ones. In this study, 35 leafrelated traits and 30 peduncle-related traits were investigated by light microscopy of 15 samples from 11 Iranian species of Ptreocephalus. Our results showed that there were two types of midrib, six types of leaf indumentum and five types of peduncle indumentum. Crystalized calcium oxalate was observed in the leaves and peduncles of most species except in P. plumosus and P. brevis. The profiles of the peduncles were hexagonal, circular or elliptical. The vascular cylinder shape varied from circular to sinuate form. P. wendelboi, with a very different morphology as compared with other species, also exhibited different anatomical characters. The hexagonal sections of peduncle in P. ghahremanii and P. kurdicus and two samples of P. szovitsii were found to be very similar. However, the mentioned characters were found to be less informative or charachterisation of other species. In conclusion, the results showed that the anatomical characters of the leaves and peduncles might have some taxonomic importance in the identification of some species of the genus Pterocephalus.
