nent on the lower surface, ascending, curved-anastomosing, the 
reticulations distinct, slender, rather lax; petioles 5 to 8 ram 
long. Heads terminal, solitary or in threes, the slender pedun- 
cles about 3 cm long, the bract-scars at about the middle, the 
heads in fruit globose, dense, about 8 mm in diameter. Cap- 
sules crowded, somewhat angular, oblong-obovoid, about 2.5 
mm long, the upper part hirsute, the persistent calyx-teeth 4, 
very short.

A rather characteristic species in the group with Neonauclea gracilis 
(Vid.) Merr., and N. philippinensis (Vid.) Merr., but rather nearer the 
latter. It is distinguished by its yellowish-green, fewer-nerved leaves. 
HEDYOTIS Linnaeus 
HEDYOTIS LUZONIENSIS sp. nov. 
Frutex circiter 1 m altus, ramosus, hispidus, ramulis quadran- 
gulatis; foliis oblongo-ovatis ad elliptico-ovatis, usque ad 5 cm 
longis, obtusis, scabridis, subtus praesertim ad costa nervisque 
hispidis, nervis utrinque circiter 4; inflorescentiis axillaribus, 
solitariis, pedunculatis, 3 ad 6 cm longis; capsulis anguste obo- 
voideis, hispidis, circiter 5 mm longis. 
An erect branched shrub about 1 m high, parts distinctly his- 
pid. Branches and branchlets dull-brownish, the latter distinctly 
4-angled, slender. Leaves pale-greenish when dry, slightly shin- 
ing, firmly chartaceous, oblong-ovate to elliptic-ovate, 2.5 to 5 
cm long, 1.2 to 2.2 cm wide, subequally narrowed to the obtuse 
apex and to the acute base, scabrous, the lower surface hispid, 
especially on the midrib and lateral nerves ; lateral nerves about 
4 on each side of the midrib, not prominent, curved, anastomos- 
ing; petioles hispid, 2 to 4 mm long; stipules broad, hispid, 
abruptly contracted into a 3 mm long beak. Inflorescences axil- 
lary, solitary, peduncled, 3 to 6 cm long, 2.5 to 3 cm wide, hispid, 
the branches few, spreading, the primary bracts foliaceous, ob- 
long, obtuse, narrowed below, 5 to 6 mm long, secondary ones 
spatulate, 2 to 3 mm long, the bracteoles linear, 1 to 1.5 mm long. 
Calyx immediately after anthesis about 3 mm long, the lobes 
4, oblong-ovate, obtuse, 1 mm long. Capsules oblong-obovoid, 
5 mm long, base acute, hispid, their pedicels 2 to 3 mm long.

This species has much the aspect of Hedyotis elmeri Merr., but differs 
in its hispid indumentum and its smaller, fewer-nerved leaves. It is at 
once distinguished from H. macgregorii Merr. by its elongated inflorescences.
