Herbs, often woody below, or shrubs. Leaves odd-pinnate; leaflets striate, with the 

 lateral veins oblique to the midrib and parallel; stipules setaceous, or broader and striate. 

 Flowers racemose, the racemes either terminal, with or without smaller racemes also in the upper 

 axils, or apparently opposite the leaves (in this case the racemes are really terminal, and an 

 axillary branch is produced which in its turn bears a teiminal raceme and an axillary branch, 

 &c. ; this is often repeated several times), or rarely only axillary, the individual flowers usually 

 in clusters of 2-6 at each node of the peduncle; bractlets none. Calyx campanulate, furnished 

 within with a more or less developed disk; lobes subequal, or the lowest one longer, the upper 

 two usually more or less united. Petals clawed. Blade of the banner suborbicular, more or 

 less sericeous without. Blade of the wings obliquely obovate or oblong, slightly coherent 

 with the keel-petals, with a basal auricle on the upper side. Stamens usually partly raona- 

 delphous at first, the upper filament being free at the base, adnate at first to the staminal 

 sheath in the middle, but usually separating later; anthers uniform. Ovary sessile, many- 

 ovuled; style inflexed or incurved, sub-corneous at the base, most commonly glabrous; stigma 

 terminal. Pod sessile, flat, 2-valved, many-seeded 



Type species, Cracea villosa L. 



Stem monopodial; racemes terminal and axillary, not opposite the 

 leaves. 

 Terminal raceme (or panicle) first and best developed, the axillary 

 ones if present smaller and later. 

 Stipules broad, ovate, many-ribbed, conspicuous, colored and 



persistent; pod glabrous except on the sutures. 

 Stipules narrow, from lanceolate to setaceous, 1-3-ribbed, at- 

 tenuate. 

 Pod glabrous. 

 ' Pod pubescent. 

 Leaflets 11-41. 



Corolla 1 cm. long or more. 



Plant tall, 3 dm. high or more; racemes many- 

 flowered; leaflets linear -oblong to elliptic- 

 lanceolate or oblanceolate (only the terminal 

 one ubovate in C. lat ideas). 

 Leaflets rounded or obtuse at the apex, mostly 

 oblong or oblanceolate. 

 Leaflets oblanceolate, leathery, glabrate 



above; racemes very long and dense. 

 Leaflets linear-oblong to elliptic. 

 Leaves rather thin. 



Racemes long and lax. 

 Racemes short and rather dense. 

 Leaves rather thick, subcoriaceous, 

 strongly reticulate; racemes elongate 

 but dense. 

 Leaflets lanceolate, acute. 

 Plant low, rarely more than 2 dm. high; leaflets 

 obovate, green above, silky-canescent beneath. 

 Corolla 6-7 mm. long; plant slender; leaflets linear- 

 oblanceolate. 

 T eaflets 1-11. 



Leaflets more or less coriaceous, oblanceolate to 

 obovate or elliptic. 

 Plant shrubby, erect; racemes dense, many- 

 flowered; leaflets more than 2 cm. long. 

 Leaflets linear-oblanceolate, not conspicuously 



reticulate, shining above. 

 Leaflets broader, strongly reticulate, dull above. 

 Plant herbaceous from a woody root, decumbent; 

 racemes short, few-flowered; leaflets less than 2 

 cm. long. 

 Leaflets membranous, lanceolate, acute; racemes lax.
