3. Psychotria rubiginosa Elmer, n. sp. in herb. 



A shrub 2 to 5 m. high, the branchlets rather stout, densely dark brown pubes- 

 cent. Leaves oblong lanceolate to oblong or elliptical oblanceolate, 20 to 30 cm. 

 long, 5 to 9 cm. wide, subcoriaceous, reddish brown when dry, glabrous and shin- 

 ing above, rather densely uniformly papillose pubescent beneath, the apex short, 

 sharp, usually abruptly acuminate, gradually narrowed below to the acute base, 

 the margins recurved; nerves 14 to 17 on each side of the midrib, prominent 

 beneath, parallel, slightly curved upwards, anastomosing, the reticulations very 

 lax, petioles stout, about 2 cm. long, glabrous above, densely pubescent beneath ; 

 stipules ovate, about 1 cm. long, coriaceous, pubescent, the apex usually with 

 two short slender teeth. Inflorescence terminal, about 15 cm. long, the pedmicle 

 6 to 9 cm. long, the panicle ovate in outline 7 to 8 cm. wide, the branches spread- 

 ing, densely rufous pubescent, the branches subtended by short persistent bracts. 

 Flowers white, fragrant, sessile in clusters of threes at the tips of the branchlets, 

 each subtended by a small bracteole. Calyx glabrous or very slightly pubescent, 

 about 2 mm. long, its rim with 5 shallow teeth. Corolla 2 to 3 mm. long, glab- 

 rous on the outside, cleft into 5 oblong obtuse segments. Stamens 5, the filaments 

 glabrous, 1 mm. long; anthers about 1 mm. long. Style not exceeding the corolla, 

 the stigma bifid. Fruit 2-celled, each cell 1-seeded, obovoid, nearly 1 cm. long, 

 orange red when mature, glabrous, shining, black and somewhat wrinkled when 

 dry; seeds flat on the ventral, convex on the dorsal surface, glabrous, not ridged.

 ridges and in ravines, forests 600 to 900 m. 



4. P. tacpo (Blanco) Rolfe, Journ. Linn. Soc. Bot. 21 (1884) 312. 



(2319 J/ei/er) January; {1951, 2360 Borden) October, January; [6008 Leiberg) 

 July. In thickets below 50 m. Endemic. 



5. P. manillensis Bartl. in DC. Prodr. 4 (1830) 522. (?) 



(1480 Ahern's collector) July; (1771 Borden) August; (6758 Elmer) No- 

 vember; (479, 510 Whitford) July; (5008 Leiberg) July. In forests 100 to 

 400 m. Endemic. 



Bartlings description is too short to warrant absolute identification, the speci- 

 mens here referred to his species strongly resembling Psychotria tacpo, differing 

 however in the fewer nerved leaves and slightly fimbriate-ciliate margins of the 

 bracteoles and calyx teeth. These specimens were identified by Mr. Elmer as 

 Psychotria philippinensis C. et S., but that species has axillary, not terminal, 

 peduncles.

22. LASIANTHUS Blume. 



1. Lasianthus bordenii Elmer, n. sp. in herb. 



A shrub about 2 m. high, the branches rather densely pubescent with long, 

 spreading, fulvous hairs. Leaves oblong-ovate, distichous, 2 to 2.5 cm. apart, 



4 to 6 cm. long, 1 to 3 cm. Avide, membranous, the apex short sharp acvuninate, 

 the base inequilateral, rather abruptly subtrmicate-rounded, often more or less 

 cordate, glabrous and shining above, paler and shining beneath, the nerves and 

 midrib densely pubescent with long fulvous hairs, the reticulations with few
