Ophiorrhiza is a genus of flowering plants in the coffee (Rubiaceae) family. Species of the genus contain camptothecin, an alkaloid used to make chemotherapeutic agents.[2][3] So many of Ophiorrhiza species are endemic to certain areas of western Ghats. Species include:
- Ophiorrhiza acuminata[4]
- Ophiorrhiza blumeana[5]
- Ophiorrhiza bracteata[5]
- Ophiorrhiza cantoniensis
- Ophiorrhiza carinata
- Ophiorrhiza caudata[2]
- Ophiorrhiza dulongensis
- Ophiorrhiza filistipula
- Ophiorrhiza japonica
- Ophiorrhiza kuroiwai[6]
- Ophiorrhiza liukiuensis[4]
- Ophiorrhiza longiflora
- Ophiorrhiza lurida
- Ophiorrhiza major[5]
- Ophiorrhiza michelloides[7] [8]
- Ophiorrhiza mungos
- Ophiorrhiza nutans
- Ophiorrhiza prostrata[1]
- Ophiorrhiza pumila[4] [9]
- Ophiorrhiza rosea
- Ophiorrhiza rugosa
- Ophiorrhiza succirubra
