感觉番杏科的分属迟早要大合并，现在好多一属一种的情况，也是醉了

以前确实是三个亚属的，据国内多肉大神说，去年权威机构已正式分成Haworthia、Haworthiopsis、Tulista三 ...

找到你说的Haworthiopsis和Tulista了。

Recent phylogenetic studies have demonstrated that the three sub-genera are actually relatively unrelated (Hexangulares was shown to be a sister-group of genus Gasteria, Robustipedunculares more closely related to genus Astroloba, and Haworthia as an out-group related to Aloe). In recognition of the polyphyletic nature of the genus, it has been proposed that Hexangulares and Robustipedunculares be moved into new separate genera ("Haworthiopsis" and "Tulista" respectively).

Botanists had long noticed differences in the flowers the three sub-genera, but had previously considered those differences to be inconsequential, although the differences between species in the same subgenus definitely are. The roots, leaves and rosettes do demonstrate some generic differences while wide variations occur even within one species.

目前还只是研究和个人建议，没有进入正式的标准。。。

软叶、硬叶拆伙也是迟早的事情，两个习性、样貌差那么多，就是因为开花相似硬挤一起也不是太科学。而且软叶和硬叶杂交情况并不多。

不过幸好我没养硬叶，所以还不会困扰
