xi, c, 2 Merrill: Notes on the Flora of Borneo 91 



our Philippine material somewhat in leaf -shape, and in its duller indu- 

 mentum, while the flowers are nearly sessile. Other than the three species 

 considered above, and S. ferrugineus Benth., represented by Native collector 

 690 from near Kuching, there are at least three other distinct species 

 represented in our Bornean collections, but the specimens are rather 

 inadequate. 



DERRIS Loureiro

FORDIA Hemsley 



FORDIA ANGUSTIFOUOLA sp. nov. 



Arbor glabra vel subglabra; foliis usque ad 40 cm longis, 

 foliolis circiter 17, estipellatis, coriaceis, lanceolatis vel anguste 

 lanceolatis, usque ad 14 cm longis et 3 cm latis, tenuiter acumi- 

 natis, basi acutis, subtus pallidis, nervis utrinque circiter 8; 

 racemis e ramis vetustioribus, usque ad 25 cm longis, multifloris ; 

 floribus circiter 1 cm longis, brevissime pedicellatis. 



A nearly glabrous tree. Leaves up to 40 cm long, glabrous 

 or nearly so. Leaflets about 17, coriaceous, estipellate, lanceo- 

 late to narrowly lanceolate, 10 to 17 cm long, 2.5 to 3 cm wide, 

 apex rather slenderly acuminate, base acute, the upper surface 

 rather pale when dry, the lower much paler than the upper; 

 lateral nerves about 8 on each side of the midrib, prominent, 

 curved; petiolules 5 mm long or less. Racemes from the older 

 branches, solitary or in pairs, up to 25 cm in length, many- 

 flowered, sparingly pubescent. Pedicels about 1 mm long, some- 

 what pubescent. Calyx cup-shaped, somewhat inequilateral, 

 subtruncate, about 3 mm long and wide, the teeth broad, obscure, 

 externally slightly pubescent. Standard externally subferrugi- 

 neous-puberulent, about 10 mm long, 6 mm wide, retuse, spread- 

 ing or reflexed in anthesis, narrowed below into a short, broad 

 claw. Wings narrowly oblong, rounded, as long as the standard, 

 about 1.8 mm wide, the claw slender, about 3 mm long; keel up 

 to 2.5 mm wide, the claw equalling that of the wings. Stamens 

 glabrous, the vexillary one free at the base, united with the 

 others above. Ovary linear, minutely appressed-pubescent, nar- 

 rowed upward into the slender curved style. Pod flat, about 2 

 cm wide, the valves much twisted when dry.
