acuminate, 1 to 1.5 mm long. Pedicels stout, about 1 mm long. 
Calyx glabrous, 3 mm in diameter, the lobes broadly ovate, 1 
mm long, acute. Petals red, the corolla 4 mm long, the free 
parts of the petals oblong-ovate, acute, about 3 mm long. Tube 
3 to 3.5 mm long, ovoid to subglobose, 5-lobed at the apex the 
lobes entire, rounded. Anthers 1 mm long. Ovary glabrous. 
Luzon, Bontoc Subprovince, Bauco, Father M. Vanoverbergh Ukk, April 
to October, 1910, on hillocks, altitude about 1,400 meters. 
A species manifestly allied to the widely distributed Leea sambucina 
Willd., from which it is distinguished by its very prominently nerved leaves 
and its very narrowly but distinctly winged petiolules. 
DILLENIACEAE 
SAURAUIA Willdenow 
SAURAUIA BONTOCENSIS sp. nov. 
Frutex vel arbor parva, 3 ad 6 m altus, ramulis subtus foliis 
inflorescentiisque plus minusve setosis; foliis coriaceis, oblongo- 
ellipticis, usque ad 25 cm longis, supra glabris, nitidis, subtus 
parce setosis, acuminatis, basi obtusis ad rotundatis, nervis 
utrinque circiter 18, valde prominentibus ; inflorescentiis e ramis 
vetustioribus, solitariis vel fasciculatis, paucifloris, depauperato- 
paniculatis, bracteatis, 4 ad 6 cm longis ; floribus 5-meris, petalis 
circiter 15 mm longis. 
An erect shrub or small tree, 3 to 6 m high. Branches stout, 
terete, brown, glabrous or nearly so, the younger ones rather 
densely covered with appressed or somewhat spreading, brown, 
lanceolate, acuminate, 2 mm long, setose scales. Leaves alter- 
nate, oblong-elliptic, coriaceous, 15 to 25 cm long, 7 to 12 cm 
wide, the apex shortly acuminate, base subacute or obtuse to 
rounded, margins distantly glandular-serrulate, the upper sur- 
face brownish or olivaceous, shining when dry, glabrous or nearly 
so, the lower surface somewhat paler, slightly shining, more 
or less spinulose-setose, especially near the midrib and the pri- 
mary nerves ; lateral nerves about 18 on each side of the midrib, 
very prominent, anastomosing, the reticulations very prominent, 
rather lax; petioles setose, 1.5 to 4 cm long. Inflorescence from 
the axils of fallen leaves on the branches below the leaves 
(0.8 to 1.5 cm in diameter), solitary or somewhat fascicled, of 
depauperate, bracteate panicles 4 to 6 cm long, more or less 
setose, few-flowered. Bracts leaflike, 1.5 to 2 cm long, 8 mm 
wide, narrowed at both ends, acuminate, irregularly spinulose- 
toothed, concave, prominently reticulate, the bracteoles similar 
but smaller and oblong to oblong-spatulate, 4 to 10 mm long;
