Blake Revision of Polygala 67 



Tuerckheim 3247 (BG) ; Arroyo Seco, 300 m., Prov. Barahona, Apr. 

 1912, Fuertes 1557 (BG); Cuesta de Piedro, 250 m., 6 June 1887, 

 Eggers 2364 (K). Linden 1704 (BK), placed here by Chodat, has 

 wings 3 mm. long, 2.5 mm. wide, and is very doubtfully referable to 

 this species. Close to P. grandiflora var. angustifolia T. & G., Fl. 

 N. Am. i. 671 (1840), which has even narrower nearly glabrous 

 leaves and perhaps larger flowers. 



Var. orbicularis Chod. Leaves elliptic-lanceolate or oblong- 

 lanceolate or linear, glabrescent or slightly puberulent, 3-4 cm. 

 long, 3-5 mm. wide. Flowers 5 mm. long. Lower sepals (united) 

 eglandular or with 2 pedicellate glands on each margin ; the upper 

 g'landular-ciliate. Wings with limb often broader than long, sub- 

 flabellate, subretuse. Chod. Monog. ii. 57 (1893). Not seen; 

 based on specimens from savannas near San Carlon Generale 

 (Preneloup 1004), and grassy places in calcareous soil near Cuesta 

 de Piedro, Santiago, San Domingo. 



85. P. angustifolia HBK. Annual, subsimple or rather 

 strongly branched, 9-33 cm. high, more or less densely incurved- or 

 loosely spreading-incurved-pubescent or even substrigose. Leaves 

 linear to lanceolate, acuminate to the sometimes bluntish apex, 

 mucronulate, acute to acuminate at base, subglabrous or sparsely 

 incurved-pubescent, 1-nerved, the lateral nerves 3-6 pairs or 

 obsolete, 1.3-4.5 cm. long, 2-9 mm. wide, on petioles 1-1.5 mm. 

 long; lower leaves smaller. Racemes 6-33-flowered, 1.5-7 cm. 

 long. Flowers 3-4 mm. long. Sepals oblong-ovate, obtuse, sparsely 

 ciliate at tip, with 2-3 pairs of pedicellate glands, 1.5-1.8 mm. long. 

 Wings strongly inequilateral, broadly wedge-obovate, cuneate at 

 base, retuse at apex, veiny but not strongly reticulate-veined even 

 in fruit, 3-4 mm. long, 2.7-3 mm. wide, pinkish-purple. Keel 3.8 

 mm. long. Upper petals mauve-purplish, suborbicular-obovate, 

 rather strongly veined, retuse at apex, 3 mm. long. Capsule ob- 

 long-oval, emarginate, plumpish, 2.8-3 mm. long, 1.7 mm. wide. 

 Seeds as in P. grandiflora var. leptophylla but smaller (seed 2.5 mm. 

 long, aril 0.7 mm. long). HBK. Nov. Gen. v. 405. t. 511 (1821); 

 Chod. Monog. ii. 52. t, 15. f. 22-24 (1893). P. bryzoides St. Hil. Fl. 

 Bras. Merid. ii. 44. t. 88 (1829). P. mucronata MacFad. Fl. Jam. 

 i. 47 (1837), not Willd. (err. idem). P. americana Mill. 8. angustifolia 

 (HBK.) Ktze. Rev. i. 48 (1891). Vera Cruz: Mirador, Nov. 

 1838, Linden 175 (K). Michoacan: La Baranca, 500 m., 3 Sept.
