Leaflets of Philippine Botany 



sprawling, repeatedly branched, terete, densely olivaceous 

 pubescent. Leaves widely scattering, alternate, upon 1 

 dm. long terete similarly pubescent petioles which are 

 somewhat thickened at the base, 3-foliolate; leaflets sub- 

 chartaceous, 15 cm. long by 8 cm. wide, the terminal sub- 

 elliptic symmetric one upon a 3.5 cm. long petiolule, 

 the lateral ovately subelliptic ones inequilateral and upon 

 very short but thickened petiolules, all leaflets subtended 

 by stipular appendages, base obtusely to truncately round- 

 ed, acute or short acuminate, upper surface glabrous 

 when old, beneath much paler and ferruginous pubescent; 

 midrib very prominent, with about 8 ascending and con- 

 spicuous lateral nerves on each side, the cross bars and 

 reticulations quite evident. Inflorescence terminal or from 

 the uppermost leaf axils, paniculately elongated, 3 to 

 5 dm. long, densely tawny tomentose, the relatively short 

 ultimate branches divaricately arranged; flowers rather 

 evenly scattered and alternate, the olivaceous pubescent 

 rachis a trifle raised at the point of attachment; pedicel 

 1.25 mm. long, becoming easily detached; calyx deeply 

 campanulate, similar in vestiture, 4 mm. long, divided 

 half way down, the upper pair of segments connate, the 

 3 others subequal, all obtuse or the basal one acute, 

 subtended by a fine pair of hairy appendages; petals 

 glabrous, blood red or deep purple; banner 5 mm. long, 

 the expanded portion nearly as broad, rotund, the base 

 subsagittate and narrowly clawed; keels a trifle shorter, 

 fully one half slenderly clawed, the lamina portion obli- 

 quely oblong and hastate on one side at the base; wings 

 somewhat shorter than the keels, similarly clawed, the 

 expanded portion pointed on one side of the base; stamens 

 10, in 2 unequal alternating series, 4 mm. long, united 

 below the middle, the free portion expanded, glabrous; 

 anthers orbicular, 0.25 mm. long; pistil pubescent, nearly 

 straight, equalling the stamens. Fruit 5 cm. long by 

 1.5 cm. wide below the middle or widest portion, mem- 

 branous, soft pubescent especially at the 1-seeded end, 

 brown, the back suture nearly straight; seed very flat, 

 oblong. 



Type specimen numbers 17560 in flower and 18250 

 in fruit, A. D E. Elmer, Los Banos (Mt. Maquiling), 

 Province of Laguna, Luzon, June July, 1917. Abundant 

 in the lower forested belt. 



Near Spatholobus gyrocarpm (Wall.) Benth, but our ma- 

 ture fruits are only one half as large.
