LEAFLETS oF PHILIPPINE BOTANY [Vor. Il, ART, 23 
branches usually much reduced, serrately toothed, the ser- 
ratures terminated into fine cusps, beneath tawny or grayish 
lanose, on the upper surface sparsely hispid or subglabrous 
except along the main nerves and either rugose or smooth; 
nerves conspicuous beneath, here and there provided with a 
small prickle, the reticulations evident; petiole terete, 4 cm. 
long, pubescent, strict, along the under side amply provid- 
ed with recurved spines; stipule oblong, toothed or pinnatifid. 
Inflorescence terminating into branchlets, elongated or frequently 
very short, subpendulous; the branched portions of the inflo- 
rescence shorter than the leaves, paniculate, the lower ones 
arising from the uppermost leaf axils; peduncles varying in 
length, stout, yellowish pubescent, subtended by stipulat 
bracts; pedicels at most 2 cm. long, similarly pubescent, subtended 
by smaller entire or toothed stipular bracts; the broad calyx cup 
1.5 em. wide, about as high, the 5 segments united below the 
middle, triangular in shape, acute, 8 mm. long, yellowish wool- 
ly on the outside, short grayish woolly on the inside, most- 
ly entire; petals white, shorter than the calyx, obovate to ob- 
long; stameus glabrous, inserted with the petals on the calyx 
throat; anthers broadly oblong, less than 1 mm. long; pis- 
tils strict, bearing oblique clavate stigmas; berry subglobose, 
carpels red, arising from a hairy receptacle. 
In the Philippines there are three recognizable species in 
this group. R. moluccanus Linn. which is a powerful climber 
and abounds in woods at middle elevations. R. rolfei Vid., & 
sprawling shrub inhabiting the highest mountains only. And 
R. rugosus Sm. a low shrub of the dry open plains. Linnaeus, 
species (see Rumph. Herb. Amboin. v. 88, t. 47, f. 2) has rather 
the small rounded and plainly rugose leaves of R. rugosus Sm. 
The leaves of our Philippine forms are various, ovate to 
triangular in outline, apex obtuse to acute and even acuminate, 
ochroleucous or grayish beneath, glabrous or pilose on the upper 
surface, and in texture and structure are submembranous and 
not strictly rugose. R.cumingii Kuntze may easily prove to be a 
form of this rather common and widely distributed plant.
