You have to have pollen from one inflorescence to place on the Ovules of another MJ. I would get a 10-15x mag. glass to know when to set the pollen. When it's time the ovules of an inflorescence will have a clear gelatinous liquid on each Ovule. You have to watch as anthesis on Anthuriums is a tricky thing to know unless you have a lot of experience. The pollen is gently rubbed on the Female Ovules and you then have the great chance of seeds developing on the ( what will hopefully be) Infructescence.
