Thailand : NORTHERN: Mae Hong Son, Chiang Mai, Phitsanulok, Uttaradit; NORTH-EASTERN: Phetchabun; EASTERN: Nakhon Ratchasima; CENTRAL: Nakhon Nayok; PENINSULAR: Ranong, Surat Thani, Pattani.
Distribution : India (Assam – type) to Peninsular Malaysia.
Ecology : Hill evergreen forests.
Vernacular : Kho (ค้อ)(Northern, Phitsanulok, Uttaradit).
Uses: The leaves are used for thatch and handicrafts. The fleshy mesocarp of the boiled fruit is eaten.
Conservation Status: A species of some concern since it is rather scattered in its distribution (see discussion in Barfod et al. 2010).
Notes: Livistona jenkinsiana has recently been considered conspecific with L. speciosa (Henderson 2009). However, where the two species grow sympatrically they differ in flowering and fruiting season.
