Using proper names

Calla was at one time the legitimate botanical name of what we now call
Zantedeschia.
===================

Hi Gang,

Z. aethiopica has had three other names that I can find: Calla aethiopica,
Richardia aetiopica, and Colocasia aethiopica. No doubt the latter name was
coined with a very broad concept of the geneus Colocasia in mind.

Jim M. hit the nail on the head when he pointed out that "legitimate"
botanical names can change. I think all four names (above) were validly
published, in the sense that "valid" names are those published according to
the rules of the ICBN.

The nice thing about names becoming standardized (i.e., legitimate) is that
such case usually means a clear understanding of a genus has developed. It
is when we don't quite underrstand all the biology that Nature is tossing at
us that names can keep changing. Smart folks (such as members of this email
list) help by growing and studying plants, and by reporting on them.

Cordially,

Joe

Cool tonight, the last Crinum americanum scape of the season was taken out
by a frost a few days ago.
