Other Information

Species of this genus where particularly softafter for their well rounded trunks. It apparently yield a very high grade quality of timber. Other species in this genus are also used by local people for its oil, medicine, food and fodder. By 1908, Bourdillon already reported that species of this genus have became very rare. And the logging may be the major raison for the extinction of the species. No new report are known after 1908.The species is only known from the Ariankavu and Shendurni Valley I Quilon district in Kerala. It was recorded as very localized. It only occurs in the evergreen forest tropical rain forest in the hills at about 300 m altitude
