a few longer subspreading hairs intermixed. Leaves elliptic, sub- 

 acute to obtuse, barely mucronulate, cuneate at base, sparsely in- 

 curved-pubescent beneath, subglabrous above, the ca. 6 pairs of 

 lateral nerves fairly prominent, 1.8-2.7 cm. long, 8-11 mm. wide, 

 on petioles 1.5-2 mm. long. Racemes 15-45-flowered, 4-7 cm. 

 long. Flowers 4.5-5 mm. long. Sepals lance-oblong, obtuse, 

 slightly involute, with 2-3 hairs at apex and 2-3 pairs of pedicellate 

 glands on margin, otherwise glabrous, 2-2.4 mm. long. Wings 

 broadly inequilaterally wedge-obovate, cuneate at base, slightly 

 undulate at the rounded apex, only slightly veiny, 5 mm. long, 3.5 

 mm. wide. Keel 4.3 mm. long. Upper petals with orbicular di- 

 lated apex, 3.9 mm. long. Capsule oblong, emarginate, cuneate at 

 base, 4.5 mm. long, 1.8 mm. wide. Seed shortly silky-pilose, 3.2 

 mm. long. Aril 0.9 mm. long, pubescent. Molt. & Gomez in

 species is apparently the same as that to which the name P. violacea 

 Aubl., clearly described and figured as with a cristate keel, is most 

 unaccountably referred by Chodat. T. 2. Fig. 46. 



Subgenus V. CHAMAEBUXUS (DC), comb. nov. 



Sepals herbaceous, free, the upper usually persistent, all persis- 

 tent in one species. Wings petaloid, oblong, deciduous (persistent 

 in one species). Keel oblong, gibbous toward apex, with distinct 

 cylindric or conic infra-apical rostrum, not otherwise crested. Upper 

 petals oblong, united below to the staminal tube. Stamens mona- 

 delphous, united for more than half their length, glabrous. Stig- 

 matic lobes subapproximate, the upper tufted, the lower obliquely 

 elevated, not tufted. Capsule small or medium, scarcely winged, 

 membranous-herbaceous. Seeds pubescent. Aril generally 2-lobed 

 and appressecl, sometimes rostrate. Polygala L. sect. Chamae-

 few others from the southwestern United States, form a most dis- 

 tinct section which may be called, in allusion to its beaked keel,
