Need Anthurium anatomy lesson

From: Don Martinson llmen at execpc.com> on 2001.07.22 at 22:34:00(7083) Here is a link to a photo of the spadix of my flowering Anthurium clarinervium: http://www.execpc.com/~llmen/aclar2.jpg I realize that this species is supposed to apomictic, but could someone give me a brief anatomy lesson here? I can visualize white bumps (A), yellowish bumps (B), and brownish bumps (C). I imagine that some of these are male flowers, but are these all male, in varying degrees of maturation? Are the male and female flowers distributed evenly along the spadix? Thanks, -- Don Martinson +More Milwaukee, Wisconsin Mailto:llmen@execpc.com

It just means that the resulting seeds are produced from the mother plant's unreduced somatic tissues. The seeds of citrus are notorius for producing apomictic seedlings as well as sexually produced seedling making it hard to be sure the resulting progeny were replicants of the Mother plant or a hybrid plant which is what the breeder is looking for. In the case of Anthurium clarinervium the flowers are perfect containing both female and male parts and are whorled about the spadix from bottom to top. The female parts open first starting at the base of the spadix and moving up progrssively as several days pass. They appear as small bumps or stalks with droplets of a viscous clear or grey liquid (stigmatic fluid) on top when receptive. As they pass out of receptivity and dry up the male parts appear as yellow stamens sticking out of the spadix. No offense intended to Dr. Tom but A, B, & C all appear to me to be various stages of the male phase. Any of the female parts would either be at the top of the spadix or totally gone by at the time of the photo shown. +More The important thing to remember is that to cross pollinate an Anthurium you need male pollen and female stimatic fluid which may mean more than one plant or one plant with several inflorescences (spadices) slightly out of phase so that one has pollen and one has receptive stigmas. Or you can try storing pollen if you are that organized and intense about breeding.
