Hi, Though I am not familiar with Pamianthe specifically, I am familiar with pollination syndromes and nectaries of some Amaryllids. My two cents is in response to this: "Pictures on the PBS site do not show a long tube indicating moth pollination. Check out the first picture by Hans and the first picture by Nhu. Since my plants are month old seedlings I have no personal experience with the flowers only other peoples pictures. Both their pictures appear to show to my eyes a floral cup not a tube" Upon observation of Pamianthe pictures, the flower form seems similar to Narcissus in that the ovary is at the base of a long (normally green) flower tube which extends between the ovary and the parianth segments etc. The nectaries are at the base of the ovaries, thus requiring a very long "tongue" to reach it. -Travis
