usually smaller, the larger blades 5 cm. long by 3 em. wide below 
the middle, edges entire, gradually tapering to the acute to acu- 
minate apex, base broadly rounded or subeordate; petiole 5 mm. 
long more or less, densely hairy; midvein densely pubescent es- 
pecially toward the petiole; lateral nerves 3 or 4 on each side, only 
2 in the small blades, strongly eurved and ascending, the basal 
2 or 3 pairs arising from below the middle, the uppermost pair 
arising from the middle, reticulations none; stipule similarly pu- 
bescent, 4 mm. long, very broad, the middle portion extended into 
a few pubescent bristles. Inflorescence green except the darker 
green calyx segments, olivaceus pubescent in the dry state, 
paniculately corymbose, 3 to 5 and even 8 em. long, branched 
from above the middle; peduncles striet, 1 to 3 em. long, usually 
3; pedicles of the capitulae also striet, the lateral ones at right 
angles and 5 mm. long, subtended by hairy foliaceous braets 
less than themselves in length; flower heads subglobose, 7.5 mm. 
in diameter, severally flowered, the fruiting heads scarcely larger; 
calyx eampanulate, 3 mm. long, pubescent on the outside, gla- 
brous within, hyaline toward the base, bearing 4 rather linear 
green teeth one half as long; corolla ereamy white, 5 or more 
mm. long; segments 4, united only for the basal 1 mm., 3-veined, 
glabrous on the outside, heavily bearded along the midvein on 
the upper side below the middle, linearly oblong, obtusely round- 
ed at the apex, ultimately strongly recurved upon the underside, 
the short tube glabrous; stamens also 4, alternating with the 
petals and inserted upon the throat; filaments 2 mm. long, sub- 
compressed, brown, glabrous except the densely bearded ventral 
middle side; anthers 1 mm. long, linearly oblong, with rounded 
ends; style striet, glabrous, as long as the corolla, stigma lobes 
eurvingly divergent, thick, blackish, papillose on the stigmatie 
surface, 1 mm. long. 
Type specimen 12716, A. D. E. Elmer, Brooks Point (Ad- 
dison Peak), Palawan, March, 1911. 
Found sprawling over thickets composed of coarse grasses, 
sedges and low shrubs in dry hot sterile soil of hillocks at 500 
feet: Dedicated to Sir George King, an eminent English 
botanist. 
This species is very near to H. prainiana King and I have 
considered it as that in my first article. Recent study of more 
material revealed a number of specific differences.
