Origin
THAILAND (East): Provinces of Prachin Buri and Trat, common along streams in dry evergreen forests at low altitudes, in evergreen forests at ca. 165 m altitude, and along roads and forest edges at ca. 700 m altitude; cf. W. Arthan & al., in Kew Bulletin, 2023 [#1396]. Also recorded from the central and eastern provinces of Prachin Buri, Sa Kaeo, Chanthaburi, Rayong, and Trat as wild (acc. to Mu Chakkrapong on Facebook, 19 Sep. 2017), and from Nakhon Nayok, wild, in forests (acc. to Mu Chakkrapong on Facebook, 2 Oct. 2021, and pers. comm., Facebook, 2 Oct. 2021). — VIETNAM (Northern): Quan Sơn District of Thanh Hóa Province: along roads and forest edges.
Uses
