nervis lateralibus utrinque. 2-3, supra impressis, subtus prominentibus, 
eystolithis utrinque nullis. 
Hab. Kinabalu, Penibukan spur, 6000', in high forest undergrowth.

This plant shows a creeping rhizome, with very short internodes from which 
several aerial shoots arise at the same level. "These shoots may be single or 
branched, and are 11-14 em. in height, and leafy for 5-6 em. up the stem. 
The stipules are ligulate acuminate, 2 mm. long and 0*5 mm. across, 
membranous-glabrous, brown. The largest leaves are 2 em. long and 0*7 cm. 
broad ; the leaves are peculiar in showing a pustulate upper surface, caused 
by the bases of setose white hairs which occur in areas formed by the tertiary 
veins ; these bases are convex on the upper surface of the leaves and concave 
on the lower ; the brittle hairs may break off, but the bases persist. The 
peduncle of the d cyme seen is 6 mm. long, the latter measuring 5 mm. 
across ; there are six bracts to the involucre, two large and four smaller and 
narrower; the perianth of the ¢ flower is A-partite, each lobe showing a 
conical apical projection, with hairs; four introrse stamens are seen in the 
immature flowers. The 9 cymes are round and 3 m. across, the involucre 
is composed of bracts all more or less the same size, narrow ligulate and 
ciliate ; the 9 flowers ure pedicellate, with a minute 4-partite and gland- 
ciliate perianth, and three staminodes, as far as could be determined; the 
achene is under 1 m. in length. Sterile flowers show the usual increase in 
size in the staminodes. 
This plant, in its diminutive size and in the shape and colour of the leaves, 
is nearest Z palawanense, Roxb., from Mt. Victoria, at about 3500', but it 
differs in the peculiar pustulate appearance of the upper surface of the leaves, 
caused by the bases of setose white hairs.

The aerial shoots of this species arise singly and unbranched from the 
creeping rhizome, and are 14 cm. long ; the upper part is recurved and leafy 
for about 7-9 em. The stipules are most characteristic, being red in colour, 
membranous and very persistent, two to each leaf all down the stem ; they 
are obovate acute, 12 mm. long aud 5 mm. broad. The < cymes are long- 
pedunculate, with the peduncle sparsely pilose, 4 cm. long ; the cymes are
