SERTULUM BONTOCENSE. 
83 
appearing with the leaves, forming a terminal leafy inflorescence, 
rather densely ferruginous-pubescent. Flowers fascicled at the 
nodes, white or pink, their pedicels pubescent, 6 to 7 mm long. 
Calyx ferruginous-pubescent, cup-shaped, subtruncate, 5 to 6 mm 
deep and wide, faintly and broadly toothed. Standard about 
17 mm long, the claw 3 to 4 mm long, the lamina suborbicular, 
retuse, pubescent on the back, reflexed in anthesis, the base with 
thickened but not projecting callosities. Wings adherent to the 
keel, their claws slender, about 6 mm long, their blades narrowly 
oblong, about 4 mm wide, similar to those forming the keel. 
Vexillary filament free at the base, united with the others above. 
Ovary somewhat pubescent. Fruit very thin, oblong, 5 to 8 
cm long, 1.5 to 2 cm wide, acuminate, when young with very few 
scattered short hairs, apparently when mature glabrous or nearly 
so, one wing about 2.5 mm wide, the other less than one-half 
as wide. 
Luzon, Bontoc Subprovince, Bauco, on hillsides, altitude about 1,325 m, 
Vanoverbergh 280, in flower April, 1910, in fruit May, 1911. 
A species apparently undescribed, and quite different from any of the 
Philippine forms previously known. Although the callosities of the stand- 
ard do not project as in Derris elliptica Benth., still they are sufficiently 
evident as thickenings of the tissue, and apparently refer the present 
species to the section Paraderris. 
TERAMNUS Sw. 
Teramnus angustifolius sp. nov. 
Herba scandens omnibus partibus plus minusve ferrugineo- 
pubescens; foliolis lanceolatis usque ad 7 cm longis, vix 1 cm 
latis; calycis dentibus lanceolatis, acuminatis, aequalibus, 2 mm 
longis. 
A scandent, slender, herbaceous vine reaching 1 m in length. 
Stems 4-angled, 1.5 mm in diameter or less, rather densely 
pubescent with somewhat spreading ferruginous hairs. Leaves 
trifoliolate, the petioles, petiolules and lower surfaces of the 
leaflets more or less appressed-pubescent with ferruginous hairs, 
the stipels pubescent, acicular, about 1 mm long; petioles 1.5 to 
3 cm long; petiolules of the lateral leaflets usually about 2 mm 
long, that of the terminal one longer. Leaflets lanceolate, 4 to 
7 cm long, 5 to 9 mm wide, chartaceous, base rounded or acute, 
narrowed upwards to the apiculate apex. Racemes pubescent, 
axillary, solitary, few-flowered, 2 to 9 cm long, slender. Calyx 
4.5 mm long, appressed-pubescent, the 5 lobes subequal, lanceo- 
late, acuminate, 2 mm long. Corolla almost included in the 
calyx, blue and white; standard 5.5 mm long, the limb orbicular- 
elliptic, retuse, not auricled at the base, 4 mm long, 3 mm wide.
