马钱是一个广泛分布的属在新热带地区和它的物种被广泛用于他们的木材,在大众医药,并为制革。它们外部形态的相似性使本属的种鉴定变得困难。本研究描述和比较的木材解剖的7种ofStryphnodendronmost经常发现在巴西森林遗迹,以确定哪些解剖特征可以用于其隔离。本文研究了七种马钱子的31个样品。采用主成分分析法对木材解剖性状进行评价。种被分成两个主要的组,一致的分裂成多小叶和少小叶的种,由于存在弥漫,菱形aliform和汇合的轴向薄壁组织。在多叶组,虽然两个亚组形成由于射线宽度的细胞数量,没有一个物种是个性化的,这证实了以前的研究结果的高形态和解剖相似性的多叶物种。
StryphnodendronMart. is a widespread genus in the Neotropics and its species are widely used for their timber, in popular medicine, and for tanning. The similarities in their external morphology make species identification difficult in this genus. This study describes and compares the wood anatomy of the seven species ofStryphnodendronmost frequently found in Brazilian forest remnants, in order to identify which anatomical features can be used in their segregation. From seven species 31 samples ofStryphnodendronwere studied. Principal Component Analysis was used to evaluate wood anatomical characters. The species were separated into two main groups, congruent with the division into multifoliolate and paucifoliolate species, due to the presence of diffuse, lozenge-aliform and confluent axial parenchyma. In the multifoliolate group, although two subgroups were formed due to ray width in number of cells, none of the species were individualised, which corroborates previous findings of high morphological and anatomical similarities of the multifoliolate species.
