Petrosaviaceae
Sign in to savePetrosaviaceae is a family of flowering plants belonging to a monotypic order, Petrosaviales. Petrosaviales are monocots, and are grouped within the lilioid monocots. Petrosaviales is a very small order composed of one family, two genera and four species accepted in 2016. Some species are photosynthetic (Japonolirion) and others are rare, leafless, chlorophyllous, mycoheterotrophic plants (Petrosavia). The family is found in low-light montane rainforests in Japan, China, Southeast Asia and Borneo. They are characterised by having bracteate racemes, pedicellate flowers, six persistent tepals, s

无叶莲科（学名：Petrosaviaceae）也叫樱井草科，是无叶莲目（Petrosaviales）的唯一科，只包括2属—无叶莲属（Petrosavia）和樱井草属（Japonolirion）共4种，分布在中国、日本和东南亚岛屿一带。 1981年的克朗奎斯特分类法将其列在霉草目，1998年根据基因亲缘关系分类的APG 分类法认为应分为两个独立的科—无叶莲科和樱井草科，但无法分入任何一个目，只是直接放在单子叶植物分支之下，2003年经过修订的APG II 分类法将两科合并，但仍然没有能归入任何一目。直到2009年，APG III分类法让其自成一目。 外部链接 《中国植物》中的Petrosavia Japonolirion osense的照片[永久失效連結] NCBI中的无叶莲科 CSDL中的无叶莲科 照片 取自“https://zh.wikipedia.org/w/index.php?title=无叶莲科&oldid=47604433” 分类： 无叶莲科 植物科名 隐藏分类： 物种微格式条目 含有拉丁語的條目 自2017年12月带有失效链接的条目 条目有永久失效的外部链接

Petrosaviaceae is a family of flowering plants belonging to a monotypic order, Petrosaviales. Petrosaviales are monocots, and are grouped within the lilioid monocots. Petrosaviales is a very small order composed of one family, two genera and four species accepted in 2016. Some species are photosynthetic (Japonolirion) and others are rare, leafless, chlorophyllous, mycoheterotrophic plants (Petrosavia). The family is found in low-light montane rainforests in Japan, China, Southeast Asia and Borneo. They are characterised by having bracteate racemes, pedicellate flowers, six persistent tepals, septal nectaries, three almost-distinct carpels, simultaneous microsporogenesis, monosulcate pollen, and follicular fruit.
==Taxonomy== The family has only been recognized in modern classifications; previously, the family members were typically treated as belonging to the Liliaceae. The APG II system recognized the family and assigned it to the clade monocots, unplaced as to order. The APG III system of 2009 and the APG IV system of 2016 placed the family Petrosaviaceae in the order Petrosaviales.
