The type of this species is probably not extant, and as I have not seen 
the original description, or Hooker's reprint of it, my conception of the 
species is based on Cogniaux's description. The form here considered as 
referable to Jack's species is widely distributed in the Philippines and is 
characterized by its prominently 4-angled, slender, ultimate branchlets, 
and its lateral inflorescence. In a note made by myself at Kew some years 
ago, attached to one of the specimens cited above I have observed that our 
Philippine material agrees better with Javan specimens {Zollinger 443) 
than with Cuming 889 from the Philippines, both cited by Cogniaux as 
representing Jack's species. Memecylon calderense A. Gray, reduced to 
M. paniculatum Jack by Cogniaux, certainly represents a specifically dis- 
tinct form. Even removing this form from Memecylon paniculatum Jack, 
the material cited above, as representing Jack*s species, presents consider- 
able variation.

22. MEMECYLON PALLIDUM sp. nov. 
Species M. paniculate valde affinis, differt foliis subtus pallidis 
minute pustulatis, inflorescentiis cymosis sed floribus dense 
aggregatis, ad apices ramulorum capitate dispositis. 
A small tree, glabrous except the somewhat brown-furfura- 
ceous inflorescence. Branches terete, brownish, the branchlets 
slender, distinctly 4-angled, or near the uppermost node narrowly 
winged. Leaves oblong to narrowly oblong-ovate, coriaceous, 
12 to 18 cm long, 4 to 8 cm wide, pale and shining when dry, the 
lower surface decidedly paler than the upper, minutely and 
rather densely pustulate, the apex sharply acuminate, the base 
broadly rounded, cordate; lateral nerves about 15 on each side 
of the midrib, very prominent on the lower surface, anasto- 
mosing with the somewhat arched, prominent, submarginal 
nerves; petioles 2 mm long. Inflorescence axillary, solitary, 
cymose, about 4 cm long, the peduncle 2 cm long or less and with 
the radiating branches 4-angled and sparingly brown-lepidote, 
the branches usually about 6, umbellately arranged, up to 1.8 
cm long, each bearing at its apex a head of numerous pedicelled 
flowers, the thickened apical part of the branches about 5 mm 
in diameter. Pedicels 2 to 2.5 mm long. Calyx broadly funnel-
