Blake — New Plants of the Genus Stylo s anthe s . 51 



The type number of this species was distributed as Stylosanthes viscosa 

 Swartz. 5. subsericea belongs to the section Styposanthes, however, and 

 in no way suggests 5. viscosa. It is distinguished among the species of 

 its section by its dense subsericeous pubescence and its strongly mucronate 

 leaflets. The fruit when known will doubtless furnish additional char- 

 acters. 



Section Eustylosanthes. 

 Stylosanthes floridana, sp. nov. 



Stems few, herbaceous, apparently erect, 0.8 to 2.5 dm. high, slender, 

 striate, rather densely but inconspicuously pubescent with appressed or 

 ascending hairs ; leaves rather few, shorter than the internodes, 3-f oliolate ; 

 sheaths of the stipules 3 to 5 mm. long, appressed-pubescent chiefly near 

 the margin, the stiff linear-subulate 1-nerved teeth 3 to 4 mm. long; 

 petioles appressed-pubescent, 1.5 to 3 mm. long, the rachis 1 to 1.5 mm. 

 long; leaflets subsessile, linear-elliptic, 9 to 15 mm. long, 1.3 to 2.5 mm. 

 wide, cuspidate-mucronate, rounded at base, entire, firm, puberulous along 

 costa above, slightly pubescent at base beneath, the 3 to 5 pairs of 

 veins prominent beneath, the lowest pair elongated to form a submarginal 

 nerve; spikes subglobose, 6 to 10 mm. long, about 8-flowered, not hispid; 

 primary bracts unif oliolate, the sheaths 3 to 4 mm. long, pilose-ciliate and 

 somewhat pilose on back, the teeth subulate from an ovate 3-nerved base, 

 2.5 to 3 mm. long, the blade linear-elliptic, 4 to 10 mm. long, rarely with 

 a few hispid-pilose hairs; secondary bracts 2, lanceolate, 2.5 to 3.5 mm. 

 long, entire, acuminate, free, paleaceous-scarious, densely pilose chiefly 

 inside and on margin above the base with long, flexuous hairs ; axis rudiment 

 none; bractlet similar to the secondary bracts, 1 to 2 mm. long, at maturity 

 usually united laterally nearly to apex with one of the secondary bracts; 

 stipe-like base of calyx 2.5 mm. long, the calyx limb 3.5 long, 5-lobed, 

 the lobes densely ciliate and more or less pilose dorsally with crisped hairs, 

 the 2 upper lobes obtuse, the lateral acute, the lowest longest; corolla 

 evidently yellow; blade of banner suborbicular, rounded, 4 mm. long and 

 wide, the claw about 1 mm. long; lateral petals obovate, 4.5 mm. long, 

 clawed, retrorsely auriculate-spurred on upper side at base of blade and 

 with an internal blunt spur of the same length ; keel emarginulate, somewhat 

 denticulate at tip, the petals free only at base, the blades broadly auricu- 

 late at base, obtusely saccate-spurred at base within; stamens with didy- 

 mous anthers equaling the style, the others somewhat shorter; basal joint 

 of pod very small, densely pilose; fruiting joint ovoid to oblong-ovoid, 

 rather plump but somewhat compressed, like the beak densely pilosulous 

 with crisped hairs, strongly 3-ribbed on the sides and favose-reticulate, 

 the body 3.5 to 4 mm. long, 2.5 to 2.8 mm. wide, the stoutish incurved- 

 hooked beak 0.5 to 0.8 mm. long. 



Type in the U. S. National Herbarium, no. 859518, collected at De 

 Funiak Springs, Walton County, Florida, July 3, 1891, by G. B. Sud-
