ETYMOLOGY. The specific epithet and Thai name are in honour of Dr Somkid Siripatanadilok, the former Associate Professor of the Department of Forest Biology, Faculty of Forestry. He taught the forest biology component of courses in field forest biology (in Peninsular Thailand, Khao Chong Botanical Garden is one of several study areas of the course), anatomy of trees, plant tissue culture and research techniques in forest biology (plant microtechniques) when the first author was an undergraduate student and a graduate student at Kasetsart University. He encouraged and supported the first author to work in the laboratory for plant tissue culture as an undergraduate student (1994 – 1997). He was the former co-advisor of the first author in his master's degree (1997 – 2000). He was a superb and a brilliant teacher, actively involved in many aspects of forest science in Thailand.
VERNACULAR NAME. Som Kaeo Somkid (ส้มแก้วสมคิด) (suggested here); Som Kaeo (ส้มแก้ว) (Satun) (from A. F. G. Kerr 14580).
