# Flowers sessile or sl.ort-peduncled, mainly involucrate by petiolate leaves at the summit 

 of the branches : petals reddish purple : low perennial with habit somewhat of Stylosanthes. 



S. ciliaris, L. Diffuse, many-stemmed, a foot or less high, strigose-pubescent : leaves oblong 

 or narrower, obtuse or retuse at both ends, or not rarely with cusp at tip, serrate above the 

 middle, 3 to 9 lines long, loug-petioled : stipules filiform- or spatulate-liuear, conspicuous, at 

 least the uppermost and the petioles hirsute-ciliate or barbate : petals quarter to near half 

 inch long : carpels 5 to 8, turgid, very strongly rugose-reticulated and over tiie back not 

 rarely tuberculate or muricate, dehiscent apex bicuspidate. — Syst. Nat. ed. 10, ii. 114.5, &

* * Flowers solitary or clustered in the axils, or at length sparingly paniculate or glomer- 

 ate at the summit of the stem in a few species, more or less pedunculate : calyx 5-augled, 

 the summit in bud pyramidal : petals mainly yellow. 



-I— Stems diffusely decumbent or prostrate from a perennial root, filiform, sometimes villous 

 with scattered long and spreading hairs, or destitute of them in the same species : leaves 

 small, mostly subcordate at base, on filiform petioles of about equal length, about equalled 

 by the filiform axillary peduncles : herbage minutely canescent : carpels mostly 5, little 

 compressed, rugose-reticulated on the thin sides. 



S. diffusa, HBK. Leaves from subcordate and roundish to lanceolate with almost truncate 

 base, crenate-dentate : petals 3 or 4 lines long (yellow, in specimens seeming white), much 

 surpassing the calyx : carpels barely apiculate or the dehiscent apex with two short stout 

 points. — Nov. Gen. & Spec v. 257, bat petals not " violacea," nor capsule "apice depressa; "

S. SUpina, L'Her. Leaves round-cordate to cordate-ovate (largest an inch long) : petals 2

H— -(— Stems erect : leaves rather long-petioled, crenate-dentate, nearly all cordate or sub- 

 cordate : calyx ovate, with 5 broadly deltoid lobes: carpels 10 to 12, their apex before 

 apical dehiscence 2-mucronate or 2-awned. 



S. COrdifolia, L. Annual (in tropics suffrutescent), densely and minutely soft tome ntose 

 and velvety, very leafy : stem robust, rather tall : leaves ovate-cordate (1 to 3 inches long), 

 sometimes obscurely angulate-lobed : flowers all short-peduncled, glomerate or clustered:
