摘要
在马来西亚半岛,Rafflesia有7种,其中R. kerrii(和R. su-meiae)在其他5种中尤为突出。其他5个物种,R. azlanii, R. cantleyi, R. parvimaculata, R. sharifah-hapsahiae和R. tuanku-halimii,彼此足够接近,在其第一个被描述的物种R. cantleyi之后被称为R. cantleyi复合体。刁曼岛有R. cantleyi种群,由于其岛屿位置,与大陆群隔离。本研究旨在确定刁曼岛一个选定地点的形态变异。对12种花进行了花被裂片上的疣(斑点)图案、花膜上表面的疣(点)、花孔形状、花突形状和花蕊类型等特征的研究。这些特征已经被用来定义R. cantleyi复合体中的物种。将当地刁曼种群的变异与大陆cantleyi r.c entleyi复合体的变异进行了比较,两者的变异幅度大致相同。这支持了R. cantleyi是一个高度多态性的单一物种的观点,并且在R. cantleyi复合体中描述的物种应该减少到品种。
On the morphological variation of Rafflesia cantleyi (Rafflesiaceae) on Pulau Tioman, Pahang, Peninsular Malaysia
In Peninsular Malaysia, Rafflesia is represented by seven species of which R. kerrii (and R. su-meiae) stands out distinctly from the other five. The other five species, R. azlanii, R. cantleyi, R. parvimaculata, R. sharifah-hapsahiae
and R. tuanku-halimii, are collectively close enough to each other to be referred to as the R. cantleyi complex after its first-described species, R. cantleyi. Pulau Tioman has a population of R. cantleyi, which, because of its island location, is isolated from
the mainland complex. This study was conducted to determine morphological variation in a selected location in Pulau Tioman. Twelve flowers were studied with respect to characteristics such as wart (blotch) pattern on perianth lobes, warts (dots) on upper surface of the diaphragm, shape of
the aperture, shape of processes and types of ramenta. These are the characters that have been used to define species in the R. cantleyi complex. The variation in the local Tioman population was compared with the variation in the R. cantleyi complex on the mainland, which is
about the same magnitude. This supports the idea that R. cantleyi is a single highly polymorphic species and that the species that have been described in the R. cantleyi complex should be reduced to varieties.

An international electronic-only journal on the biodiversity, evolution and biogeography of plants (systematics,
floristics, phylogeny, morphology, anatomy). For floristic studies, the focus is on tropical Africa south of the
Sahara; tropical Southeast Asia with a strong emphasis on Malesia; South America with emphasis on the
Guianas. The language is English.
