 alternate, linear-spatulate to oblanceolate or obovate, 1.3-4 cm. long, 1.5-8 mm. wide, rounded 

 to acuminate, mucronulate; peduncles solitary, 2.3-7.5 cm. long; racemes conic-capitate, 

 becoming ovoid-ellipsoid or thick-cylindric, acute becoming very obtuse, 1-1.7 cm. thick, 1-3.7 

 cm. long; bracts linear-subulate, ciliolate, at length deciduous or sometimes persistent, 5.5-6.5 

 mm. long; flowers subsessile, yellow turning deep- or bright-green in drying; sepals elliptic- 

 lanceolate to linear-subulate, 3-5.3 mm. long, cuspidate-acuminate, ciliate; wings elliptic, 

 6.5-7.5 mm. long, 1.8-2.8 mm. wide, acuminate and somewhat involute at apex into a cusp 

 0.6-0.9 mm. long, scarcely narrowed at base, sparsely ciliolate, 3-5-nerved; keel 4.5-5.8 mm. 

 long, the crest on each side of 3 linear entire to 3-parted lobes; anthers 6; capsule oval or sub- 

 orbicular-oval, 1.6-2 mm. long, 1.2-1.6 mm. wide; seed ellipsoid or subpyriform, pilose, with 

 prominent thick blunt rostrum at base, 0.8-1.8 mm. long; aril 0.7-1.1 mm. long, the 2 linear 

 scarious lobes appressed, one third to nearly as long as seed.

 thick-cylindric, usually apiculate, very densely flowered or rarely and abnormally loose at base, 

 1.5-2 cm. thick, the axis 7.5 cm. long or less; bracts subulate-attenuate, ciliolate, deciduous, 

 3.5-5 mm. long; pedicels narrowly winged, 2.2-4 mm. long; flowers lemon-yellow, turning
