Blake Revision of Polygala 53 



softly pilose like the inflorescence-axis and pedicels with subspread- 

 ing slightly curved shorter and wide-spreading slightly longer hairs. 

 Leaves ovate, obtusish to acute, mucronulate, cuneate at base, 

 firm, with about 5 pairs of lateral nerves, somewhat reticulate, 

 above dark green, softly pubescent with longish ascending hairs, 

 beneath somewhat paler, densely and softly spreading-pilose along 

 the veins, less densely or sparsely so between them with spreading 

 or ascending hairs, 2.5-7.1 cm. long, 1.1-2.8 cm. wide, on densely 

 spreading-pilose petioles 1.5-2 mm. long. Racemes rather loosely 

 flowered, 2.5- (at maturity) 9 cm. long. Flowers probably purplish. 

 Sepals lanceolate to ovate, acute, spreading-pilose, 3-3.6 mm. long. 

 Wings oblong, rounded at apex, abruptly cuneate at base, rather 

 densely pilose along costa and toward apex with longish spreading 

 hairs, 7-8 mm. long, 3.8-4.5 mm. wide. Keel glabrous, 7 mm. long. 

 Upper petals obovate-spatulate, densely ciliate below, 6.5 mm. 

 long. Capsule elliptic, emarginate, more or less densely ciliolate 

 and puberulous with short wide-spreading hairs, rather deeply but 

 narrowly emarginate, 9-11 mm. long, 7-8.8 mm. wide. Seed ellip- 

 soid, pilose, 6 mm. long. Aril 3 mm. long, with very indistinct 

 umbo, scarious, somewhat pubescent and ciliate, with obliquely 

 ascending dorsal edge and obliquely descending ventral, the mar- 

 gin about 6-toothed, not lobed. Chod. Monog. ii. 35 (1893).

 Veraguas.
