LUCINAEA DC. 



Lucinaea epiphytica Elm. n. sp. 



Epiphytic shrub; stem repeatedly branched and forming 

 tangled or sabscandent masses; braiKihlets grayish brown, 

 ringed by the old leaf scars, flexible though very wiry, the 

 glabrous ascendingly curved tips obscurely angular. Leaves 

 opposite, chiefly toward the distal ends of the branchlets, 

 thick and rigid, the entire margins subin volute in the dry 

 state, darker green above, drying very unequally brown on 

 the two sides, mostly acute, rounded or broadly obtuse at base, 

 elliptic or nearly so, the larger ones 7 cm. long by 3 cm. 

 wide, glabrous even in the young state; midrib impressed 

 along the upper side; lateral nerves 7 to 9 pairs, relatively 

 obscure, oblique, nearly straight, their tips only faintly united, 

 reticulations obsolete; petiole 1 to 2 cm. long, subterete, 

 narrowly grooved above, glabrous. Infrutescence erect, ter- 

 minal; peduncle 1, 2 or 3-clustered, 2 to 3 cm. long, angular 

 or subterete, shining pale green, nearly black when dry, 

 each subtended at the base by a series of short blunt loosely 

 imbricated blackish brown and nearly glabrous deciduous 

 bracts; fruiting heads subglobose, 2 cm. in diameter, bearing 

 about 9 young sessile fruits which are crowded upon the 

 circular much flattened more or less fleshy torus; fruits 

 whitish, glabrous, ellipsoidly oblong, 1 cm. long, 6 mm. 

 thick, with a deep cupshaped apex; ovary composed of 5 

 irregular masses, bearing a much thickened stigmatic crust; seeds 

 numerous, imbedded, reddish brown in the dry state, compressed, 

 subcordate or lenticular in shape, 1 mm. across, smooth. 



Type specimen number 14147, A. D. E. Elmer, Cabad- 

 baran (Mt. Urdaneta), Province of Agusan, Mindanao, Oc- 

 tober. 1912. 



Upon the main limbs of large trees on the wind swept 

 forested summit of Cawilanan peak at 5000 feet elevation. 

 "Salimpatungao" is its vernacular Manobo name. 



Primarily differs from L. monocephala Merr. in having 

 usually more than one head upon shorter stalks; leaves in oura 

 not reddish tinged in the dry state, generally widest below or 

 at the middle, not above it, their laminae thicker in text-
