Igersheim & Ueachirakan 900914–1/5 (BKF); Ton Ouat FaWaterfall, 19 Oct. 2004, Kesonbua 110 (KKU)]; Narathiwat [no locality, 12 Jan. 1986, Niyomdham 1131 (AAU, BKF, P)].
Distribution.— India, Cambodia, Peninsular Malaysia, Singapore, Borneo.
Ecology.— Common in lowland evergreen and secondary forests, also along trails in open areas, forest edges, by streams and in coastal hill forest; altitude to 450 m. Flowering and fruiting periods: September to June.
Vernacular.— Chan thana bai lek (´µÄÁ¨È) (Narathiwat); khem pa (ÁÈ¤iµ) (Narathiwat); ya-rong (¥µÃ¦) (Malay-Narathiwat).
Notes.— Tarenna wallichii is very variable as regards the shape of the leaves, which are oblong to lanceolate with inconspicuous lateral veins. The species is similar to T. quocensis, but can be distinguished by its broadly triangular calyx lobes and its smaller fruits with short persistent calyces. Its distibution, moreover, is restricted to the south of Thailand.
