petalis imbricatis, oblongis, staminibns 6, filamentis basi dilatatis tubum 
brevem efformantibus, disco nullo, ovarii rudimento sessili; foliis circa 
SO cm longis, 6- vel 7-jugatis, imparipinnatis. 
Flowers apparently dioecious, the staminate subsessile or borne on 
pedicels reaching 1.5 mm long, fascicu lately disposed on simple or 
branching peduncles 1-2.5 cm long (or very short at the apex), arranged 
along an axillary rachis about 30 cm long : calyx fleshy, 3-lobed, nearly 
cylindric, the tube about 4 mm long, the lobes nearly 2 mm long, broadly 
ovate, rounded at the apex ; petals 3, white, imbricate, oblong, 7 mm long, 
3.3 mm wide, rounded at the base, shortly and sharply acuminate at 
the apex, ferruginous-tomentose on the exposed portions of the back only ; 
stamens 6, anthers linear, 2-3 mm long, filaments 1.7-2. 5 mm long, 
linear, dilated at the base and forming a thin tube about 0.7 mm high; 
no proper disk; rudiment of ovary sessile, ovoid, 1.5 mm long, nearly 
glabrous except for a tuft of ferruginous hairs at the apex: flower-buds 
ellipsoid. 
A tree 18 m high, with a trunk 22.5 cm in diameter, not resinous 
except the inflorescence; the ultimate branches, rachises, and sepals, the 
petioles, petiolules, the under surface and the veins of the upper surface of 
the leaflets densely ferruginous-pubescent or gia Orescent, branchlets very 
pithy; leaves exstipulate, 6- or 7- jugate, odd pinnate, in all 79-82.5 cm 
long, the petiole tapering from a 6.5-9 mm wide dilated and clasping 
base to 1 mm at its apex, striate, flattened on its upper surface, petio- 
lules 1.2-1. 4 cm long, the lowest pair of leaflets inserted 23-23.5 
cm from the base, succeeding pairs following at intervals of 8.5 cm, 
7.8 cm, 7.5 cm, 6. 3-6. 8 cm, 5.8-6 cm, 5 cm (if any), respectively, and 
the terminal leaflet 3-3.3 cm; lowest pair of leaflets shorter than the 
others, apparently unequal, ovate, 15.5-18 cm long, at the apex abruptly 
narrowed into an obtuse acumen 3 cm long, truncate, rounded, or acute 
at the base, succeeding leaflets 23-35 cm long, 5-9.5 cm wide, elliptic 
or oblong-ovate; the upper surface of the lamina somewhat bluish-green, 
lateral veins on each side of the midrib 20-25, arched, forming 2 or 3 
veins on the very margin, secondary and tertiary venation also con- 
spicuous, margins of the leaflets entire or only slightly sinuate. 
Type collected at an elevation of 120 m at Sax River, District of Zamboanga, 
Mindanao, by R. S. Williams, no. 2111, in flower, February 7, 1905. 
From this species it seems impossible to separate, on the basis of existing 
collections, two unnumbered collections by Mrs. Clemens, from Camp Keithley, 
Lake Lanao, Mindanao, September, 1907. They are superficially distinct from 
Williams’ plants in the size of the paler leaves, which are almost certainly 
mature but only about 40 cm long, with leaflets only 12-15 cm long. The floral 
characters are almost identical, and the number, shape, and venation of the 
leaflets is the same.
