Hemerocallis forrestii

Diels

Asphodelaceae


Hemerocallis is a very difficult genus taxonomically, with no overall concensus amongst botanists as to how many distinct species there are and the delineation between them. The genus as a whole needs a comprehensive revision. We are trying to follow the most recent thinking for each species, though it is inevitable that a number of species we have included in the genus will have to be amended as and when a comprehensive new treatment is published.
