GENUS DIMEROCOSTUS
Dimerocostus is a genus of very tall growing neotropical Costaceae that are distinguished from Costus primarily by the bilocular (two-sectioned) ovary constrasted against the trilocular ovary in Costus. The flowers appear to be terminal on leafy stems, but the stems will sometimes continue to grow through the inflorescence and then even produce a second inflorescence, making them nominally lateral flowering plants. The flowers have broad showy labellums in either white or yellow.
They are widely distributed from Nicaragua to Bolivia but mostly uniform in appearance except for the separately named species and subspecies.
