LEAFLETS OF PmiLIPPINE BOTANY [Vor. LI, Art. 23 
cent, also prickly. Leaves scattered along the branchlets, 
flat, rigidly spreading, ovate, 10 cm. long, one half as wide 
toward the base, frequently smaller, glabrous except along 
the nerves, apex obtuse or acute, base shallowly cordate, mar- 
gin finely serrate; nerves 5 to 7 on each side, much ascend- 
ing, the midrib usually prickly; petiole about 2 cm. long, 
prickly and yellowish brown pubescent; stipules 1 cm. long, 
lanceolate, densely pubescent on the outer side, edges usual- 
ly rolled in over the subglabrous ventral side. Paniculate 
inflorescence terminating the branchlets, 1 to 2 dm. long, 
one half as much across; branches divaricate, pubesceut, the 
larger ones prickly; pedicels as well as the branchlets sub- 
tended by bracts, about 5 mm. long, densely covered with 
a yellowish gray tomentum, flexuose; calyx 12 mm. long, 
tomentose on the outer side, united at the base, the 5 seg- 
ments slightly unequal in width, sharply acuminate, rather 
thick and nerved; flowers usually 3-clustered, apetalous; stamens 
numerous, 6 mm. long, inserted upon the calyx rim; fila- 
ments glabrous, straight, subequal, sharply pointed; anthers 
0.75 mm. long, nearly as wide, basifixed; carpels glabrous 
subtended by numerous light yellow hairs; styles also gla- 
brous, 4 mm. long, the stigmatic apex only slightly thicken- 
ed; berries flat, few seeded, shining, nearly black. 
It is rather common in the limestone formation of the 
pine region about Baguio, and is, besides the previous one, 
the only apetalous species known from the Philippines. The 
Igorrotes call it Kobat. Only known from the type locality. 
4. Rubus brevipetalus Elm. n. sp. 
A lofty tree climber; stems rigid, numerously branched 
and forming large tangled bushes; branchlets green, with a 
few blunt spines; twigs glabrous or minutely puberulent, more 
numerously provided with short flattened recurved spines. 
Leaves thick and rigid, alternatingly scattered along the branch- 
lets, dark lucid green above, much lighter or yellowish green 
beneath, curvingly condulplicate on the dorsal side, with slight- 
ly recurved tips, quite variable in size, the smaller ones 
elliptic, the larger ones ovately oblong, 10 cm. long by 5 
em. wide, glabrous on the upper surface except along the 
sunken midvein; margins subentire toward the rounded base,
