Type specimen number 14184, A. D. E. Elmer, Cabad-

 October, 1912. 



Collected at the base of a 1000 feet high cliff in the 

 Tvarrow and wooded Catangan creek ravine at about 3500 

 feet altitude. The Manobos call it "Pamahogan." 



Very close to M. merrillii C. B. Rob. {M. ferruginea 

 Merr.) but our membranous leaves are glabrous except the 

 midvein and lateral nerves and drying green on both sides; 

 pubescence also lighter brown and much shorter and denser. 



Mitrephora pictiflora Elm. n. sp. 



Small erect tree; stem terete, 15 cm. thick, 7 m. high, 

 straight, branched from the middle; wood yellowish white, 

 odorless and tasteless, only moderately hard; bark smooth and 

 greenish gray on surface, otherwise the color of the wood; 

 main branches slender, divaricately spreading, repeatedly re- 

 branched; the twigs terete, numerous, the slender apical por- 

 tion ferrugineously pubescent, lax. Leaves subchartaceous, hor- 

 izontal or descending, with very hairy bracts, slightly paler 

 green beneath, greenish when dry, 10 to 14 cm. long by 

 3 to 45 cm. wide, occasionally much smaller, recurved 

 toward the slenderly acuminate apex, margins entire, alter- 

 natingly scattered along all branchlets, oblongish or ovately 

 oblong, glabrous except the nerves beneath, petiole 5 to 8 

 mm. long, thickened and subterete, usually with a pubescent 

 bud in its axils, minutely ringed transversely, hairy but 

 becoming glabra te; midvein bold beneath, with ferrugineus 

 hairs on both sides, ultimately becoming glabrate; the 5 to 

 7 lateral pairs of nerves much ascending and curved, the 

 tips of the upper ones usually united some 3 mm. below 

 the edge, quite conspicuous beneath, reticulations dense and 

 equally obscure from both sides. Flowers solitary or 2 or 

 even 3 clustered from very short ferrugineus and few bracteate 

 stalks, coming to antheais at different times, odorless, pendant; 

 pedicel recurved, yellowish green, slender, densely covered 

 wiih ferrugineus hairs, 2 cm. long, subtended at the base 

 by minute bracts, provided with a broad similarly colored 

 and hairy bract at the middle or a trifle above it. Sepals 3, nearly
