Biology:Ophiorrhiza

From HandWiki

Ophiorrhiza is a genus of flowering plants in the coffee family (Rubiaceae). It contains 378 species native to the Indian subcontinent, Indochina, China, Taiwan, Japan, Malesia, Papuasia, Queensland, and the South Pacific.[1] Species of the genus contain camptothecin, an alkaloid used to make chemotherapeutic agents.[2][3] Many Ophiorrhiza species are endemic to certain areas of the Western Ghats.

Species include:

  • Ophiorrhiza acuminata[4]
  • Ophiorrhiza australiana[1]
  • Ophiorrhiza gajureliana
  • Ophiorrhiza blumeana[5]
  • Ophiorrhiza bracteata[5]
  • Ophiorrhiza cantoniensis
  • Ophiorrhiza carinata
  • Ophiorrhiza caudata[2]
  • Ophiorrhiza dulongensis
  • Ophiorrhiza filistipula
  • Ophiorrhiza japonica
  • Ophiorrhiza jomyi[6]
  • Ophiorrhiza kuroiwai[7]
  • Ophiorrhiza liukiuensis[4]
  • Ophiorrhiza longiflora
  • Ophiorrhiza lurida
  • Ophiorrhiza major[5]
  • Ophiorrhiza michelloides[8][9]
  • Ophiorrhiza mungos
  • Ophiorrhiza nutans
  • Ophiorrhiza prostrata[10]
  • Ophiorrhiza pumila[4][11]
  • Ophiorrhiza rosea
  • Ophiorrhiza rugosa
  • Ophiorrhiza succirubra
  • Ophiorrhiza meenachilarensis[12][13]
