l'^8 Leaflets of Philippine Botany [Vol. V, Art. 92 



Discovered in a stony but very wet soil of a deeply 

 shaded depression near a stream between Duros and Cawi- 

 lanan peaks at 3500 feet altitude. "Tayaning" in Manobo. 



Very near to P. nickersonii Elm. but leaf reticulations 

 on nether side not wholly glabrous; young twigs, petiole 

 and inflorescence woolly pubescent. 



Polyalthia urdanetensis Elm. n. sp. 



A sleuder erect small tree; stem 8 cm. thick, 7 m. 

 high, straight, branched from above the middle; wood rather 

 soft, dingy white, odorles-s and without taste; bark smooth 

 and mottled, latericius except the epidermis; main branches 

 scattered horizontally, rebranched; twigs lax, lenticelled, the 

 young tips isabellitius hairy. Leaves similarly spreading or 

 descending, subcliartaceous to subcoriaceous, alternate, flat 

 or only the entire marginal sides slightly curved upon the 

 lower paler green surface, curing brownish, the nether side 

 slightly strigose, apex acute to acuminate, base rounded, 

 elongated oblong, the average ones 2 dm, long by 5 cm. 

 wide at the middle; midrib very pronounced and strigose 

 beneath, minutely verrucose on both sides; main lateral nerves 

 about 8 on each side, with secondary intervening ones, like- 

 wise bold and strigose beneath, their tips truncately united 

 or coarsely reticulated, reticulations rather coarse and very 

 prominent from beneath only; petiole 3 to 5 mm. long, 

 very thick in proportion, when young strigose but dark brown 

 and glabrous in the dry and old leaves. Flower rigid, 

 cremeus, odorless; pedicels pendulous, green, very slender, 5 

 to 8 cm, long, thickened at the distal end, subglabrous, 

 subtended at the base by a few very unequal sharply point- 

 ed and hairy deciduous bracts, solitary, nearly opposite 

 the uppermost leaves; calyx very rigid, rotately spreading, 

 ovately rounded, subglabrous, 5 mm. wide and a trifle 

 shorter in length, cremeus; petals likewise rigid and of 

 the same color, yellowish green puberulent on the outer 

 basal portion, 6, united about the base, well separating in 

 anthesis, broadly obtuse, 1 cm. long by one half as wide, 

 their basal portion concavo-convex, the 3 outer petals some- 

 what broader relatively and usually flat, the sides of
