摘要

摘要:描述了仅在南非东开普省的Great Fish河和Mzimvubu河下游悬崖上已知的球茎草(水蛭科)。其平卧的大灰绿色叶莲座直径可达300毫米，宿存卵形至宽卵形渐尖的叶片300 × 140毫米，从尖端干燥成薄的纸状条纹宿存骨架。对这个分类群的描述构成了对南非和纳米比亚的悬崖多肉和球茎多肉分类群的广泛调查的一部分。提供了一个表，其中选择了东开普省类似种类的Bulbine的特征。南非夏季降雨地区的悬崖栖息的Bulbine物种也提供了一个关键。

Bulbine sceletium, a new cliff-dwelling Bulbine species (Asphodelaceae) from the Eastern Cape

Summary: Bulbine sceletium (Asphodelaceae), only known from cliffs along the lower Great Fish and Mzimvubu Rivers, Eastern Cape Province, South Africa, is described. Its decumbent large greyish-green leaf rosettes are up to 300mm in diameter with persistent ovate to broadly ovate-acuminate leaves 300 × 140mm, drying from the tips into a thin papery striate persistent skeleton. The description of this taxon forms part of an extensive survey of cliff-dwelling succulent and bulbous-succulent taxa in South Africa and Namibia. A table is provided with a selection of characters of similar species of Bulbine in the Eastern Cape. A key is also provided to the cliff-dwelling Bulbine species of the summer rainfall parts of South Africa.
