In general, your descriptions of wallisii and floribundum seem o.k. but in
cultivar-nomenclature, species names are often discarded because the genetic
history (breeding history) includes material of more than one species. Such
is the case with quite many Spathiphyllum cultivars. The name Spathiphyllum
'Alpha' in itself is enough to identify the cultivar and keep its name
unique. Why would you go to lenghts to try to discover if it has the right
to have a species name as well? It may even be misleading.
Sorry, rather depressing answer, isn't it?
