VIII, c, 1 Merrill: Shidies on Philippine Rubiaceae, I 47 
A species well characterized by its narrow, undulate, lanceolate leaves 
and small flowers. In vegetative characters quite different from our 
other Philippine species.

Arbor 6 ad 8 m alta, omnibus partibus plus minusve adpresse- 
hirsutis; foliis chartaceis vel subcoriaceis, late ovatis, breviter 
acuminatis, 12 ad 16 cm longis, nervis utrinque circiter 12; in- 
florescentiis terminalibus, hirsutis, corymbosis, multifloris; caly- 
cis segmentis lanceolatis, acuminatis, 1 cm longis, uno petiolato, 
late ovato, albo, 6 ad 7 cm longo ; corolla extus hirsuta, tubo

A tree 6 to 8 m high. Branches somewhat compressed, red- 
dish-brown, lenticellate, glabrous, the younger ones prominently 
appressed-hirsute with brownish hairs. Leaves in equal pairs, 
broadly ovate, chartaceous or subcoriaceous, 12 to 16 cm long, 
the upper surface glabrous or sparingly hirsute, the lower sur- 
face appressed-hirsute on the midrib and lateral nerves, apex 
shortly acuminate, base broad, rounded or somewhat decurrent; 
lateral nerves about 12 on each side of the midrib, distinct, curved 
upward; petioles hirsute, 1 to 4 cm long; stipules ovate to 
oblong-ovate, densely hirsute, about 1 cm long. Inflorescence 
terminal, corymbose, hirsute, densely many-flowered, 6 to 8 cm 
long and wide, the bracts and bracteoles oblong to oblong-lan- 
ceolate, 5 to 8 mm long. Calyx-tube about 6 mm long, densely 
hirsute, the lobes lanceolate, acuminate, about 1 cm long, the 
enlarged one petioled, white, its lamina broadly ovate, 6 to 8 cm 
long. Corolla-tube hirsute, green, nearly or quite 2 cm long, the

Luzon, Benguet Subprovince, Mount Tong'lon, Phil. PL 770 Merrill, 
May, 1911, in forests, altitude about 1,800 m. 
A species quite distinct from the common low-country Mussaenda 
philippica Rich., and probably most closely allied to M. niacrophylla Wall., 
from which it seems to be sufficiently different to be described as a distinct 
species. 
PAVETTA Linnaeus 
PAVETTA BRACHYANTHA sp. nov. 
Frutex vel arbor parva 3 ad 5 m altus, partibus junioribus 
inflorescentiisque pubescentibus ; foliis chartaceis, oblongo-ellip- 
ticis vel oblongo-lanceolatis, utrinque acuminatis, nitidis, 6 ad 
12 cm longis, in siccitate nigricantibus ; corymbis multifloris, 
pubescentibus, bracteis late ovato-orbicularibus, acuminatis, brac-
