Occasionally it occurs that a male plant of T. fortunei besides the usual spadices produces also a few other spadices which carry really hermaphroditic flowers. The hermaphroditic and completely fertile flowers are almost exactly like the male flowers, but are a little larger and with the carpels well evolute, the latter about as long as the filaments, furnished with a ring of silvery hairs all round.
