Species Notes

LaBerge and Ribble (1975: 433) record the type locality of A. zygandeni as California, Riverside County, Gavilan, 28 March 1932, by C.M. Dammers, on Zygadenus fremontii, in contrast to Cockerell’s (1932) original work; though Cockerell (1932: 1975) included material from Gavilan (near Riverside) these were collected 8 March 1931 and indicate as paratypes.
