A small tree, glabrous or nearly ao. Branches grayish, somo- 
what compressed, sparingly lenticellate, the younger ones very 
obscurely puberulent. Leaves oblong to oblong-ovate, 15 to 20 
cm long, 5 to 8 cm wide, coriaceous, somewhat brownish when 
dry, the upper surface shining, the lower a little paler and dull, 
base broadly rounded-cordate, only a little narrowed below the 
middle, the sinus about 3 mm deep, the lateral lobes very broad, 
rounded, apex very broadly rounded-acuminate or obtuse; lateral 
nerves 11 on each side of the midrib, prominent on the lower 
surface, very obscurely anastomosing, the reticulations not prom- 
inent; petioles 5 to 10 mm long, when young obscurely puber- 
ulent; stipules oblong, rounded, about 1 cm long, slightly pubes- 
cent, deciduous. Peduncles terminal, in threes, about 4 cm long, 
very obscurely puberulent or nearly glabrous. Heads (in bud) 
globose, 1 to 1.5 cm in diameter, yellowish-brown when dry, 
subtended by two, oblong, pubescent, early deciduous bracts which 
are about 5 mm in length; bracteoles none. Calyx-tubes not 
united, rather densely pale-hirsute, the tips of the calyx-lobes 
densely puberulent, yellowish-brown.

altitude about 1,000 meters, locally known as kambabalog. 
A rather strongly marked species, characterized by its leaves being 
broadly rounded-cordate at the base, oblong, and blunt or very broadly 
blunt-acuminate at the apex, most closely allied to Nauclea bartlingti 
DC. and N, vidalii Elm.

A tree, the young branchlets, petioles, peduncles, and the lower 
surfaces of the leaves, at least on the midrib and nerves, min- 
utely grayish-puberulent. Branches terete, light-gray, glabrous. 
Leaves oblong-ovate, chartaceous, 11 to 22 cm long, 4 to 11 cm 
wide, the base rounded or acute, the apex very broadly blunt- 
acuminate or obtuse, the upper surface glabrous, subolivaceous 
when dry, slightly shining, the lower somewhat paler and 
somewhat brownish-yellow; lateral nerves 8 to 10 on each side 
of the midrib, prominent, faintly anastomosing, the primary 
reticulations slender, distinct, rather lax, subparallel; petioles 
1 to 3 cm long; stipules deciduous, not seen. Peduncles up to 5
