Discussion | When not in flower, the rosettes of Hypoxis curtissii can be easily mistaken for Cyperus, which grows in the same habitats. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
In the southern part of its range, Hypoxis wrightii can be found flowering shortly after fire at any time of year. The name H. micrantha Pollard was misapplied to H. wrightii by A. E. Brackett (1923) and subsequent authors. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
