Pistia cultivars?

From: Jduft at aol.com on 1998.11.26 at 20:12:34(2784) Is there a Pistia expert out there in aroid land? There are a couple of new water lettuce cultivars being offered by aquatic plant nurseries. 1. One is the same size as P. stratiotes, but the rossettes are smooth surfaced and yellow green (Offered by water nurseries in Florida). 2. The second is a dwarf, hardly 1-1/2 inches across (offered by Paradise Water Gardens in Mass). Their origins are unknown. I would like to put a name to each for a publication, and have photos of each.
