82 MERRILL. 
about 20, in two rows, 3 to 4 mm long. Carpels about 12, acu- 
minate, 5 mm long, in fruit radiately arranged, laterally compres- 
sed, lanceolate, 1.5 to 2 cm long, about 5 mm deep. 
Luzon, Bontoc Subprovince, Bauco, Vanoverhergh 101^8, January, 1911, 
in forests, altitude about 1,650 m. 
The second species of the genus to be found in the Philippines, differing 
from Illicium philippinense Merr., to which it is closely allied, in its larger 
flowers, more numerous perianth-segments, and larger and more numerous 
mature carpels.

RHYNCHOSIA Lour. 
Rhynchosia volubilis Lour. Fl. Cochinch. (1790) 460; DC. Prodr. 2 (1825)

altitude about 1,400 m. 
Not previously reported from the Philippines; China to Formosa and 
Japan. 
The specimen seems to be referable to Loureiro's species, as that is at 
present interpreted; it differs from it, as described, in having the leaflets 
shortly acuminate, not obtuse. The Luzon plant is matched in all respects 
by one from Formosa, Nakahara 195, July, 1905. 
DERRIS Lour. 
I 
Derris oblongifolia sp. nov. § Paraderris, 
Frutex erectus vel scandens, partibus junioribus plus minusve 
ferrugineo-pubescentibus vetustioribus glaber vel subglaber; 
foliis pinnatis, circiter 20 cm longis, foliolis 13, oblongis vel 
anguste oblongo-obovatis, acuminatis, 3 ad 7 cm longis ; racemis 
axillaribus, ferrugineis, quam folia multo brevioribus; floribus 
fasciculatis, albidis vel roseis, circiter 1.7 cm longis, vexillo piloso, 
basi subcalloso; leguminibus oblongis, 5 ad 8 cm longis, 1.5 ad 2 
cm latis, subglabris. 
A scandent woody vine, or suberect and about 1 m high, the 
younger parts more or less ferruginous-pubescent, in age becom- 
ing glabrous or nearly so. Branches dark-brown, lenticellate, 
slightly pubescent, the younger parts very densely ferruginous- 
pubescent. Leaves alternate, about 20 cm long, pubescent with ^| 
scattered, short hairs, becoming nearly glabrous; leaflets 13, 
oblong to narrowly oblong-obovate, when young membranaceous, 
} 
becoming firmly chartaceous, 3 to 7 cm long, 1.5 to 2 cm wide, 
base rounded or subacute, the apex shortly and rather abruptly 
acuminate, the lower surface slightly paler than the upper, in ^ * 
age becoming quite glabrous except for scattered hairs along ' "* 
the midrib; lateral nerves about 10 pairs, slender but distinct; 
petiolules 2 to 3 mm long. Racemes in the upper axils, solitary.
