Derris canescens Em. n. sp. 



A scandent and sprawling shrub. Branches tough, 

 terete, densely brown pubescent, the older ones numer- 

 ously whitish lenticelled. Leaves alternate, scattered, 

 up to 15 cm. long, oddly pinnate, more or less 21 foliolate 

 from near the base, the rachis densely tawny pubescent; 

 leaflets membranous, alternate or subopposite, short but 

 distinctly petiolulate, elliptically oblong, broadly rounded 

 at both ends, terminated in a minute hairy point, 3 cm. 

 long by 1.25 cm. wide for the larger ones, paler and 

 more hairy beneath, easily falling. Inflorescence lateral 

 from the lower leaf axils or from below the foliage of 

 the short lateral branchlets, paniculate, 3 to 5 cm. long, 

 solitary and branched from near the base or sometimes 

 2 or 3 clustered, short pubescent; the ultimate branchlets 

 short and mainly clustered toward the top, subtended 

 by lanceolate hairy bracts of unequal lengths, the basal 

 ones being the largest; pedicels 2 to 3 mm. in length, 

 pubescent, terminated by a pair of similarly pubescent 

 stipels; calyx 4 mm. long, nearly 3 mm. wide, thin or 

 membranous, truncately rounded at the base, the broad 

 upper segment notched, the 3 others equal, divided half 

 way down to the base, rather acutely pointed; petals 

 glabrous, whitish and finely sprinkled with purple, 6 

 mm. long; banner subelliptic, its basal one third clawed; 

 keels and wings very similar, a trifle shorter, the basal 

 one half slenderly clawed, the expanded portion oblong 

 and toothed at the basal free side, apex broadly rounded; 

 stamens 9, united except the apical one tbird free por- 

 tion, glabrous, all bearing pale yellow basifixed anthers, 

 the filaments gracefully curved from the middle; pistil 

 glabrous, the ovary portion strap-like, narrowly winged 

 along both sides and upon a long sparsely hairy stipe, 

 the distal end with a short ascending style. 



Type specimen number 17883. A. D. E. Elmer, Los 

 BaQos (Mt. Maquiling), Province of Laguna, Luzon. June- 

 July, 1917. Discovered to be a large tree climber at 

 the lower limit of the forests. 



Probably as near to Derru cwmngxi Benth. as to any 

 other, but our inflorescence is quite different and the 

 very flat ovary is glabrous. 



Spatholobus sanguineus Elm. n. sp. 



A liana with 5 ,'cm. thick sterns. Branches long and
