Racemes axillary, solitary, the peduncle and axis 1.5 cm long 
or less. Flowers 6-merous, about 5 mm long, curved, red, their 
pedicels 2 to 3 mm long; bracts elliptic-ovate, 3.5 mm long; 
bracteoles united to the middle, about 2 mm long and 3 mm wide, 
the lobes triangular, acute. Calyx 4 mm long, somewhat urceo- 
late, the limb produced about 1 mm. Corolla-tube about 3 cm 
long, somewhat enlarged upward, the lobes about 12 mm long, 
spatulate, much narrowed below, then broadened for a short 
distance, the limb 2.8 mm wide in the middle. Anthers linear,

This species is readily recognized among the few Philippine species of 
Elytranthe by its large leaves and long flowers. It is not closely allied to 
any previously described form from the Philippines, but seems to be allied 
to the extra-Philippine Elytranthe formosa G. Don.

ARISTOLOCHIA Linnaeus 
ARiSTOLOCHIA FOVEOLATA sp. nov. 
Frutex scandens; foliis subcoriaceis, ovato-lanceolatis, usque 
ad 12 cm longis, nitidis, sursum gradatim angustatis, apice 
acutis vel acuminatis, basi profunde cordatis, lobis rotundatis, 
subtus dense foveolato-reticulatis et minutissime puberulis ; 
fructibus axillaribus, solitariis, cylindraceis ad anguste obovoi- 
deis, circiter 3.5 cm longis. 
A scandent shrub, glabrous except for the minutely puberu- 
lent lower surfaces of the leaves. Branches nearly black when 
dry, the older ones very prominently lenticellate. Leaves sub- 
coriaceous, rather pale when dry, shining, ovate-lanceolate, about 
12 cm long, 4 to 5 cm wide across the base, gradually narrowed 
upward to the acute or acuminate apex, the base deeply cordate, 
the sinus narrow, rounded, the lobes broadly rounded and often 
overlapping, the upper surface distinctly reticulate, the lower 
densely foveolate-reticulate ; basal nerves 7 or 9, the inner pair 
nearly reaching the apex, the lower one or two pairs extending 
into the basal lobes; petioles 3.5 to 4 cm long. Capsules cylin- 
dric to narrowly obovoid, glabrous, dark-colored when dry, 
axillary, solitary, pendulous, about 3.5 cm long, 1.5 cm in dia- 
meter, the apex rounded, base attenuate.
