AMPHORALIS  Walther, 1958  

NAME OF A HERBARIUM SPECIMEN, NOT OF A LIVING PLANT.

 

Echeveria amphoralis has been described by Eric Walther in the Cactus and Succulent Journal US 30(5): 149-150 in 1958. As type he indicated Echeveria B-82 (UCBG 56.801-1), a gathering by Thomas MacDougall from the gorge of Rio Tablas near Tlaxiaco, ca 2300 m, in western Oaxaca.

The University of California Botanical Garden received the plant with the number 56.801 as E. B-82 from Scott E. Haselton, who had originally got it from Tom MacDougall, and received it a second time two years later from MacDougall directly (UCBG 58.845). While in the protologue of 1958 E. Walther indicated B-82 as type of E. amphoralis, shortly after, in Sept. 1958 & March 1959, he determined both UCBG B-82 accessions as E. skinneri. This means what the protologue of E. amphoralis indicates as its type is a gathering belonging to Eskinneri. Consequently the name of the former is invalid.

The only material to which the name E. amphoralis can be attached with certainty is the holotype sheet CAS 409844, prepared from a plant of unknown origin and at an unknown date. Beyond that the name is unusable. Needless to say that plants circulating as E. amphoralis are wrongly named.

PS

Pilbeam's text and photos under the heading Echeveria amphoralis lack any foundation.
