8 on each side of the midrib, rather prominent on the lower 

 surface, curved, obscurely or scarcely anastomosing, the second- 

 ary ones and reticulations obsolete; petioles 3 to 5 mm long. 

 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. 



ARISTOLOCHIACEAE 



ARISTOLOCHIA Linnaeus 

 ARrSTOLOCHIA 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 f oveolate-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.
