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
