56. P. americana Mill. Fruticulose, erect, several-stemmed, 
about 1.2 dm. high. Stems simple or branched, slightly flexuose, 
densely pubescent with incurved-spreading rather short equal hairs. 
Leaves ovate to obovate, acute or the lower rounded at apex, acute 
at base, mucronulate, firm but rather thin, with about 2 pairs of 
lateral nerves, somewhat reticulate, rather densely pubescent both 
sides with incurved-spreading hairs, 1.4-2.3 em. long, 8-11 mm 
wide, on incurved-spreading petioles 1 mm. long; those of the 
branches sometimes much reduced. Racemes rather loosely 
flowered, 1.2-4 cm. long. Flowers ‘‘ purplish.” Sepals lanceolate 
or oblong-lanceolate, rather densely incurved-spreading-pubescent, 
44.5 mm. long. Wings elliptic, obtuse, rather densely pubescent 
all over outside with longish incurved-spreading hairs, 5-7 mm. 
long, 3-4 mm. wide. Keel glabrous, 5 mm. long. Upper petals 
spatulate-obovate, ciliate below. Capsule (immature) elliptic, 
emarginate, reticulate, densely pubescent with straightish patent 
hairs, 6 mm. long, 5.3 mm. wide, on a spreading-pilosulous pedicel 
1.8-3 mm. long. Seed not seen. — Mill.! Gardn. Dict. VIII. ed.

57. P. HEBANTHA Benth. Suffruticulose at base, erect, 1.5-2.5 
dm. high, few-stemmed, the stems simple or slightly branched, 
densely pubescent with subincurved-spreading shorter hairs mixed 
with longer spreading hairs. Lower leaves oval or elliptic, rounded 
or obtuse at apex, mucronulate, at base broadly cuneate, thinnish, 
with 3-6 pairs of lateral nerves, somewhat reticulate, subsparsely 
pubescent with shorter and longer incurved hairs, 1.8-3 cm. long, 
1-—2.2 em. wide; middle and upper larger, oval to ovate, acute, 2.5- 
5.5 em. long, 1.1-3.2 em. wide, on petioles 1.5-2 mm. long. Ra- 
cemes rather loosely flowered, 2-4 cm. long. Flowers apparently
