outer ones longer and broader, very thick and rigid, ven- 

 trally folded, appressed pubescent on the exterior, slightly 

 so on the inner side, ovately elliptic when spread out, 

 bluntly obtuse at the apex; corolla 5 ram long, the basal one 

 half united into a broad tube, inserted about the base of the 

 ovary, the upper portion 5 to 7-segmented; segments linear, 

 1 ramw ide, glabrous, more or less rounded at the apex, 

 frequently smaller and more pointed, its throat densely 

 hairy, deciduous as a whole; stamens about 15, erect, in- 

 serted upon the corolla throat, apparently all fertile; fila-

 base to the apex; anther 2.5 mm long, shallowly cordate at 

 the base, mucronately pointed at the apex, ovoidly oblong, 

 laterally dehiscent, the emptied cell walls widely spreading, 

 bisifixed; ovary crown flatly conical, pubescent; style strict, 

 stout, 1 cm long, glabrous, terminated by a rugosely 3-angled 

 stigma. Fruits usually solitary, descending, green, fusiform, 

 2.5 cm long and 1 cm thick, glabrous, subtended by the

Type specimen numbers 14058 with flower and 13890 with 

 fruit, A. D. E. Elmer, Cabadbaran (Mt. Urdaneta), Province 

 of Agusan, Mindanao, September and October, 1912. 



The flowering specimens were collected on the windy 

 wooded ridge connecting Duros and Cawilanan peaks at 3500 

 feet altitude; the fruiting material was gathered in wet grav- 

 elly or stony ground along a deeply shaded streamlet near 

 the Catangan creek at 3000 feet altitude. The Manobo name 

 for the former is "Malobon" or "Marobon" and of the 

 latter "Silanangsang." 



Sideroxylon apoensis Elm. n. sp. 



Tree; trunk 10 m high or higher, 0.5 m thick, branch- 

 ed toward the top; the twigs quite numerous, suberect, 

 forming dense masses, at first pulverulent, ultimately glab- 

 rate, angular in the dry state; bark smoothish, gray and 

 brown mottled, with a milky sap; wood hard, yellowish 

 white, heavy, burly and yet when cut quite brittle. Leaves 

 thinly chartaceous, the entire margins strongly curved upon the 

 under side, dull ashy green above, otherwise paler in color,
