Nomenclature
I have a couple of questions I was hoping someone
could help with....
Given the following two names:
Tillandsia usneoides fo. longissima André, 1889
Tillandsia usneoides var. longissima (André) Mez, 1896
What is the difference between the two? I assume
var. stands for variety, but what does fo. stand
for? Form? Is this a case where the same plant was
reclassified a few years after discovery, or are
they two separate plants?
Thank you for your help,
-N
