646 FABACEAE

 vety pubescence ; terminal leaflet much larger and broader than the lateral : racemes 1-2.5 

 dm. long, the upper ones shorter than the leaves and fewer flowered : flowers scattered 

 along the angled peduncle for more than half its length, forming an interrupted spike-like 

 raceme, 4-20 cm. long : calyx 1-1.3 cm. long, hirsute ; lobes veined, nearly equal : corolla 

 yellow ; standard broadly oblong, hirsute along the top : pods obliquely oblong, 1.5-2 cm. 

 long, nearly straight along the dorsal and deeply rounded along the ventral suture : seeds 

 lenticular, 3.5-4 mm. in diameter, brown or sometimes light with dark markings. 

 In dry soil, Missouri to Louisiana and Texas. July to October. 



12. Dolicholus simplicifolius (Walt.) Vail. Stems erect, simple, rarely branched

 spreading or reflexed hairs : stipules ovate or ovate-lanceolate, 5-10 cm. long, reticulated, 

 persistent : leaves 1-foliolate, the blades 2-8 cm. broad, 2-5 cm. long, depressed orbicular or 

 reniform, leathery, velvety-pubescent above, resinous-dotted, reticulated, and hirsute on the 

 veins beneath, becoming glabrate with age : racemes sessile or short-peduncled, 2-3 cm. long, 

 axillary or commonly aggregated at the summit of the stem : calyx 7-10 mm. long, resin- 

 ous-dotted, somewhat hirsute and ciliate: corolla yellow: pods oblong, 1.5 cm. long, 6

13. Dolicholus interme~dius (T. & G. ) Vail. Stems erect, simple, or possibly with 

 few branches, softly pubescent-tomentose, especially on the angles, 1.2-3 dm. high : stip- 

 ules obliquely lanceolate, 6-9 mm. long, striate, red-brown, persistent : basal leaves 1-foli- 

 olate, the blades nearly orbicular or rhombic-orbicular, obtuse or depressed ; upper leaves 

 or only the uppermost 3-foliolate, the terminal leaflet 2.5-5 cm. long, its blade oval or 

 ovate-orbicular, obtuse, sparingly pubescent above, pubescent and rugosely veined beneath 

 when old ; lateral leaflets obliquely oval or oblong, 2-3 cm. long, mucronulate, some of 

 them subcordate at the base : racemes terminal and axillary, sessile or short-peduncled : 

 calyx 8-9 mm. long ; lobes slender, veined, pubescent, resinous-dotted : corolla yellow ; 

 standard glabrous, the teeth at the base much shorter than the claw : pods not seen. 



In sandy soil, Georgia to Florida and Alabama. May to June. 



14. Dolicholus er6ctus (Walt.) Vail. Stems erect, 2 dm. high or taller, simple or 

 branched above, with a soft fine pubescence : stipules lanceolate or linear-lanceolate, acumi- 

 nate, reddish brown, 4-8 mm. long, at length reflexed : leaves distant, 4-15 cm. long, the 

 basal ones often 1-foliolate ; leaflets mainly 3, the blades oval, oblong, or oblong-oval, acut- 

 ish or obtuse, 2.5-4.5 cm. long, 1.5-3.5 cm. wide, pubescent above, velvety pubescent, 

 somewhat reticulated and resinous-dotted beneath, often drooping, the terminal leaflet the 

 longest : racemes numerous, usually shorter than the petioles, very short-peduncled in the 

 axils of the leaves : flowers in compact clusters : calyx about 6 mm. long, pubescent ; 

 lobes not conspicuously foliaceous, lanceolate, acuminate, veined : corolla yellow ; standard 

 suborbicular, glabrous : pods 1.5-2 cm. long, 6-7 mm. wide, oblong, attenuate, with a 

 somewhat curved apex, rounded on the ventral suture : seeds lenticular, 3 mm. in diameter, 

 flattened, brownish.

15. Dolicholus Drummondii Vail. Stems erect, densely velutinous-tomentose, 1.5- 

 3 dm. high : stipules lanceolate, acuminate, becoming reflexed, deciduous : leaflets 3, the 

 blade of the terminal one oblong-lanceolate or sometimes oblong, 3-6 cm. long, 2-3 cm. 

 wide, acute, densely velutinous-tomentose on both surfaces, silvery above, the whole lower 

 surface dotted with numerous orange-colored glands beneath the tomentum, and the promi- 

 nent veins reticulated beneath ; lateral leaflets with narrower inequilateral acute blades : 

 racemes subsessile or very short-peduncled : calyx 6 mm. long, foliaceous, tomentulose and 

 ciliate, resinous-dotted, the upper lobe 2-toothed to considerably below the middle : co- 

 rolla included in the calyx, apparently a deep orange-yellow color ; standard round-ovate,
