An erect, glabrous shrub or tree, the branches terete, reddish-brown. 
Leaves alternate, scattered, elliptic-oblong, chartaceous or subcoriaceous, 
brown and somewhat shining when dry, entire, 7 to 9 cm long, 3 to 5 cm 
wide, the apex shortly and sharply acuminate, the base acute, the lower 
surface with numerous, scattered, verrucose ‘glands; nerves 15 to 20 on 
each side of the midrib, not prominent, anastomosing, the reticulations 
lax; petiole stout, 2 to 3 mm long. Panicles terminal, pyramidal, 
reaching a length of 20 em, the branches alternate, spreading, the lower 
ones 9 cm long, the upper ones gradually shorter, the secondary branches 
slender, 1.5 to 2.5 em long, racemosely arranged on the primary ones, 
each bearing at its apex from 3 to 7 long-pedicelled, ymbellately arranged 
flowers, the pedicels slender, 1 to 2 cm long. Calyx about 4 mm in 
diameter, the lobes 5, oblong or oblong-ovate, obtuse, entire, about 1.6 
mm long, somewhat united at the base, spreading in anthesis, not at all 
imbricate, prominently glandular-punctate with large glands, the margins

A species most closely allied to Ardisia gardneri, A. divergens, and A. ceyla- 
nica, but abundantly distinct from all. It is well characterized by its ample, 
pyramidal, rather lax panicles, long-peduncled umbels and long-pedicelled flowers.
