Vanzijlia is a genus of flowering plants belonging to the family Aizoaceae. It only contains one known species, Vanzijlia annulata.[1]
It is native to the Cape Provinces of the South African Republic.
The genus name of Vanzijlia is in honour of Dorothy Constantia van Zijl (1886–1938), South African plant collector.[2] The Latin specific epithet of annulata means ring-shaped or with an annulus.[3] Both the genus and the species were first described and published in Fl. Pl. South Africa Vol.7 on table 262 in 1927.[1] The genus is recognized by the United States Department of Agriculture and the Agricultural Research Service, but they do not list any known species.[4]
