odorless and tasteless, moderately hard, reddish toward the 
center; bark smooth, grayish mottled. Leaves horizontally 
spreading, mostly at the ends of the branchlets, alternate, 
5 to 8 dm. long, odd pinnate or otherwise, leaflets 3 to 5 
or even 7 pairs, quite rigid and chartaceous, the basal ones 
reduced, conduplicate on the upper dull green surface, much 
lighter green beneath, recurved toward the obtuse and abruptly 
recurved apex, entire, dull green in the dry state, brown 
pubescent on both sides especially the lower, oblong or the 
smaller blades subrotund, broadly rounded at the base, the 
average blade 2 dm. long and 7 cm. wide across the middle 
or below it; petiole and rachis dirty brown puberulent or 
hairy, the former thickened at the base, the latter more 
or less triangular; petiolule stout, similar in vestiture, 1 to 
1.5 cm. long; stipule nearly obsolete or merely apiculate; 
midrib conspicuously raised beneath, hairy on both sides, 
the larger blades with 20 lateral pairs whose tips are arched 
and submarginally united, the cross bars and reticula- 
tions also conspicuous. Infrutescence ascending from the leaf 
axils mostly, unbranched, 1.5 to 2.5 dm. long, short and 
densely fulvous when young, wearing glabrous, fruit bear-

ly ellipsoid, 3 cm. long, 2 cm. wide below the mid- 
dle, in the young state densely fulvous but soon becoming 
glabrate, deep purple when mature; stone ovoid, the main 
ridges terminating into sharp points at the apex and into 
a short stout base at the other end, each with a blunt

Type specimen 11215, A. D. E. Elmer, Todaya (Mt. Apo), 
District of Davao, Mindanao, July, 1909. 
Found on a wind swept forested ridge of mount Burebid 
at 3500 feet. Its particular Bagobo name is ''Ogat-calawa." 
The purple red fruits are exceedingly pretty! 
The leaves of this species are strikingly similar to those 
of C. ahernianum Merr., C. nervosum Elm., and to C. ley- 
tense Elm., but the stone of the mature fruits are entirely 
different. In the last named it is of course much smaller 
and always glabrous, subterete and minutely rugose. The
