Rotheca is a genus of flowering plants in the family Lamiaceae. Estimates of the number of species in the genus vary from about 35 to as many as 60. Three of the species are native to tropical Asia, with the rest occurring in Sub-Saharan Africa. The type species for the genus is Rotheca serrata. It had originally been named Rotheca ternifolia, but this name is now considered illegitimate.
Rotheca myricoides is native to tropical East Africa and is cultivated as an ornamental throughout the tropics.Rotheca serrata is from tropical Asia and has some medicinal use there.
In the 20th century, Rotheca was rarely recognized as separate from Clerodendrum. Rotheca was revived in 1998 as a result of phylogenetic analysis of DNA sequences. It can easily be distinguished from Clerodendrum by a combination of morphological characters.
The following description is adapted from the most recent monograph on Lamiaceae.
