186 IIOIUKSON. 
petalis imbricatis, oblongis, stamiuibus 6, Iilaiuentis basi dilatatis tiibum 
breveai eiToniiaiitiljiLs, disco nulla, ovarii rudimonto sessili; foliis circa 
80 cm longis, G- vel 7-jiigatis, imparipinnatis. 
Flowers apparently dioecious, the staminate subsesslle or borne on 
pedicels reacliing 1.5 mm long, fasciculately disposed on simple or 
In-andiing peduncles 1-2.5 cm long (or very short at the apex), arranged 
along an axillary rachis about 30 em long: calyx fleshy, 34obed, nearly 
cylindrie, the tube about -1 mm long, the lobes nearly 2 mm long, broadly 
ovate, rounded at the apex; petals 3, -svhite, 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 G, 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 tiunk 22.5 cm in diameter, not resinous 
except the inflorescence; the ultimate branches, rachises, and sepals, the 
petioles, petiolulcs, the under surface and the veins of the upper surface of 
the leaflets densely ferruginous-pubescent or glabrescent, branchlets very 
pithy; leaves exstipvdate, 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- 
lulcs 1.2-1.4 cm long, the lowest pair of leaflets inserted 23-23.5 
cm from tlie 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 
nanuwed 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, 
r 
lateral veins on eacli side of tlie midrib 20-25, arched, forming 2 or 3 
veins on the very nuirgin, 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 Zaiiil)o;inga, 
^lindanao, by E. S. WlUiaius, no. 2111, in flower, February 7, 1905. 
From this species it seems imiwssible to separate, on the basis of existing 
collections, two nnnnmbpred collections by Mrs. Clemens, from Camp Keitbley, 
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, witli leaflets only 12-15 cm long. The floral 
characters are almost identical, and the number, shape, and venation of the 
leaflets is the same.
