Blake — Revision of Polygala 99 
(Syn. Fl. 1. c.) has already pointed out that Chodat’s var. exap- 
pendiculata was based on a misapprehension of the characters of 
the northern form of the species. 
122. P. gracttis HBK. Erect slender annual, sparsely branched 
above, 4 dm. high, the stem angled, glabrous. Leaves alternate, 
linear, acuminate to the cuspidate apex, scarcely narrowed at base, 
glabrous, thickish, 3-9 mm. long, 0.2—0.5 wide, subsessile. Racemes 
slightly loose, cylindric, 1-1.7 em. long (axis becoming 3-9 cm. 
long); pedicels 0.7 mm. long. Flowers rosy, 2.6 mm. long. Upper 
sepal broadly ovate, obtuse, 1.4 mm. long; lower sepals narrowly 
oblong-lanceolate, acutish, 1.4 mm. long. Wings narrowly spatu- 
late-obovate, truncate-rounded at apex, long-cuneate at base, 3- 
nerved, 2.6 mm. long, 1 mm. wide. Keel 2.4 mm. long; crest of 
about 3 pairs of lobes, the posterior lanceolate, obtuse, adnate to 
keel, the 2 anterior linear. Upper petals oblong-ovate, obtuse or 
slightly emarginate at the apex, equalling keel. Capsule oblong- 
oval, emarginate, 1.6 mm. long, 1 mm. wide. Seed 1.5 mm. long, 
subsparsely appressed-pubescent. Aril 0.6 mm. long, its lobes 
linear-oblong, appressed. — HBK. Nov. Gen. v. 401 (1821); Chod. 
Monog. ii. 228. t. 24. f. 8-9 (1893). — Cuapas: plains, temperate 
region, June (1864-70), Ghiesbreght 861 (G). Also in S. A., and 
reported by Chodat from the Antilles. — T. 2. Fic. 76. 
123. P. panicutaTa L. Slender annual, sparsely or densely 
branched, erect, 0.6—4 dm. high, the stem and leaves densely pedi- 
obllate-glandular. Leaves alternate (except for a few whorls of 24 
below), linear or linear-spatulate, rarely linear-obovate, mucronate 
at the acute apex, cuneate at the distinctly petioled base, 1-nerved, 
slightly revolute, more or less pedicellate-glandular, 8-18 mm. long, 
1-2.5(4) mm. wide, on petioles 0.5 mm. long. Racemes loosely 
flowered, cylindric, 6 em. long or less (the axis becoming 9.5 cm. 
long), 5-6 mm. thick; bracts early deciduous; pedicels 0.7-1 mm. 
long. Flowers rosy or purplish, rarely white, 2-2.5 mm. long. 
Upper sepal broadly ovate, obtuse, bearing 2 glands at base, 1.3 
mm. long; the lower oblong-ovate, obtuse, bearing 2 glands at base, 
1.2 mm. long. Wings obovate or spatulate-obovate, rounded at 
apex, long-cuneate at base, 3-nerved, 2-2.5 mm. long, 0.7-1 mm. 
wide. Keel 2-2.5 mm. long; crest of 3—4 pairs of lobes, the posterior 
broadly lanceolate, acutish, adnate to keel, the 2-3 anterior linear 
to linear-lanceolate, entire. Upper petals lanceolate-oblong, acut-
