The plants are endoparasites of vines in the genus ''Tetrastigma'' (Vitaceae) and lack stems, leaves, roots, and any photosynthetic tissue. Only the flowers emerge from the roots or lower stems of the host plants. ==Relationships== Past taxonomic works have varied as to the classification of Rafflesiaceae. Most traditional classifications that were based entirely on morphological features considered Rafflesiaceae ''sensu lato'' (in the broad sense) to include nine genera, but the heterogeneity among these genera caused early workers, such as Harms (1935), to recognize four distinct groups that were then classified as tribes (still within Rafflesiaceae). This tribal system was followed by Takhtajan et al. (1985). The first molecular phylogenetic study (using DNA sequences) that showed two of these tribes were not related was by Barkman et al. (2004). This study showed three genera (corresponding to tribe Rafflesieae, that is, ''Rafflesia'', ''Rhizanthes'', and ''Sapria'') were components of the eudicot order Malpighiales. The genus ''Mitrastema'' (tribe Mitrastemeae) was shown to be unrelated and a member of the order Ericales. Later that year, Nickrent et al. (2004), using additional molecular data, confirmed the placements by Barkman et al. (2004) and also examined the positions of the two other tribes, Cytineae (''Bdallophyton'' and ''Cytinus'') and Apodantheae (''Apodanthes'', ''Berlinianche'',and ''Pilostyles''). Nickrent et al. (2004) showed Cytineae was related to Malvales and Apodantheae to either Malvales or Cucurbitales. Thus, the group traditionally classified as a single family, Rafflesiaceae, was actually composed of at least three distinct and very distantly related clades, with their similarities due to convergent evolution under their common parasitic lifestyle. A goal of taxonomy is to classify together only plants that all share a common ancestor, i.e., are monophyletic. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Rafflesiaceae」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
