Re: Will the real A. scabra please....

Dear Breck,

Close enough.

Agave scabra Salm-Dyck in Gentry (1982) and the plant seen in collections
under that name is correctly named Agave asperrima Jacobi. It is an Agave
species with broad rough (or rarely smooth) leaves that is very common in
the Chihuahuan desert of Mexico and adjacent Texas.

Agave scabra Ortega is Manfreda scabra (Ortega) McVaugh, formerly known as
Manfreda brachystachya (Cavanilles) Rose. Manfreda scabra is a bulbous
species with deciduous leaves. It is widespread in southern Mexico,
Guatemala, Honduras and El Salvador but seldom grown in collections.

Dear Steve, let me see now.  There is an Agave scabra Ortega, but it isn't
what we have been calling Agave scabra?  So, the agave that has been known
as A. scabra is in fact A. asperrima Jacobi, whereas the "real" Agave scabra
is some agave few people know?  Breck
