Rotheca

Rotheca is a genus of flowering plants in the family Lamiaceae.^[1] Estimates of the number of species in the genus vary from about 35 ^[2] to as many as 60.^[1] Three of the species are native to tropical Asia, with the rest occurring in Sub-Saharan Africa.^[2] The type species for the genus is Rotheca serrata. It had originally been named Rotheca ternifolia, but this name is now considered illegitimate.^[3]

Rotheca myricoides is native to tropical East Africa and is cultivated as an ornamental throughout the tropics.^[4] Rotheca serrata is from tropical Asia and has some medicinal use there.^[2]

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.^[3]
