662 LEAFLETS OF PHILIPPINE BOTANY [Vor. II, Arr. 38 
numerous and usually branched toward the ends, the sides of 
the blades decurrent nearly to the base of the 1 cm. long 
petiole. Inflorescence recurved from the lowermost leaf axils, 
spicately racemose, its stalks red, 1 to 2 cm. long; flowers 
odorless; peduncle proper red, 1 cm. long, terete, at least 
1 mm. thick, pulverulent or minutely scurfy in the young 
state; pedicels red, crowded along the upper portion of the 
rachis or axis, 8 mm. long, spreading, numerous, similar to 
the peduncle in vestiture, thickened toward the apex, sub- 
tended at the base by minute bracts; calyx composed of 5 
segments; segments triangularly elongated, 2.6 mm. long, 1.5 
mm. wide across the base, acuminate, the central portion 
dark brown in the dry state, greenish white or the tips 
becoming red, the margins provided with fine brown color- EL 
ed tack-shaped glands, otherwise glabrous or with only | 
a few similar glands scattered over the dorsal side, the upper 
one half, conduplicate on the ventral side, reflexed in ant- 
hesis; corolla 5-segmented, twisted and imbricated in the bud; 
the segments divided nearly to the base, ultimately rotately 
spreading, glabrous on the dorsal side, provided with a few 
scattering glands, 5 mm. long, 2.6 mm. wide across the 
middle or a trifle below it, subovately oblong, terminating 
in an obtuse usually twisted apex; stamens sessily inserted 
upon the base of the corolla segments; anthers light yellow, 
3.5 mm. long, at least 1 mm. wide at the base, triangularly 
elongated, mostly included, laterally dehiscent; ovary globose, 
1 mm. in diameter, glabrous; style whitish, 3 to 4 mm. 
long, terete, slender, glabrous, arising from the ovary apex, ter- 
minated by a small stigma; immature fruits glabrous, globose 
or nearly so, at least 5 mm. in diameter, bearing a short 
vestige of the style.

Distriet of Davao, Mindanao, July, 1909. E 
Discovered in wet stony soil along a densely wooded 
creek bottom near the Sibulan river at 9000 feet altitude. 
Quite rare! The Bagobos call it ‘‘Catig-catigpo’’. 
Related to A. warburgiana Mez, but young branches 
not densely covered with capitate hairs, petioles and pedicels 
twice as long in our specimens and inflorescence more num- 
erously flowered.
