''Hesperoyucca'' is a small genus of two recognized species of flowering plants closely related to, and recently split from, ''Yucca'', which is in the century plant subfamily within the asparagus family. ==Description== ''Hesperoyucca'' is distinct from ''Yucca'' in having loculicidally dehiscent fruit and a scape more than 2.5 cm diameter with reflexed (not erect) bracts. The stigma is capitate, whereas those of ''Yucca'' split into three reflexed lobes. The glutinous pollen is released in a sticky mass; that of ''Yucca'' species is released as single grains.〔(Agavaceae.com ) – page includes a key to''Yucca'' and the three recognised species of ''Hesperoyucca''〕 ''Hesperoyucca'' is also distinct in DNA analysis.
