Blake Revision of Polygala 43 



cent, the upper longer. Wings elliptic, " glabrous," thrice as long 

 as sepals, equalling corolla. Upper petals obovate, shorter than 

 keel. Capsule elliptic-orbicular, emarginate, membranaceous, cili- 

 ate, glabrous on sides. Aril apparently rather small. HBK. 

 Nov. Gen. v. 409. t. 512 (1821). P. americana Mill. a. normalis 

 Ktze. Rev. i. 48 (1891), as to synonym. Not seen; recorded by 

 HBK. from near Ario, alt. 1830 m. Chodat's description, made 

 from the types (Monog. ii. 24 (1893)) does not agree in all char- 

 acters with the original. I can discover no feature in the original 

 description to distinguish the species from Chodat's P. Albowiana, 

 but am unwilling to unite them without examining the types. 



49. P. Albow t iana Chod. Suffruticulose, several-stemmed, 

 erect, 3-4 dm. high. Stems subsimple or sparsely branched, rather 

 densely pubescent with short incurved hairs mixed with plentiful 

 longer spreading hairs. Leaves ovate (the lower, not seen, probably 

 oval), acute, cuspidate, at base rounded to cuneate-rounded, thin, 

 with 3-4 pairs of lateral veins, not reticulate, green above, pale be- 

 neath, rather densely pubescent both sides with rather long in- 

 curved hairs, 2.5-5.6 cm. long, 1.5-3 cm. wide, on petioles 1-2 mm. 

 long, pubescent like the stem. Racemes 1.5-13 cm. long, loosely 

 flowered; pedicels rather sparsely incurved-pubescent, 3.5-5.5 mm. 

 long. Flowers purplish. Sepals ovate or ovate-oblong, acutish, 

 pubescent with incurved hairs, 2-2.5 mm. long. Wings oval, 

 rounded at apex, cuneate at base, very sparsely puberulous along 

 midnerve, somewhat purplish-tinged, 5-6 mm. long, 3-4 mm. wide. 

 Keel glabrous, 6-6.2 mm. long. Upper petals oblong-subovate, cili- 

 ate toward base, 5 mm. long. Capsule elliptic, ciliate, pale, reticu- 

 late, 1.2 cm. long, 1 cm. wide, in youth sometimes slightly puberu- 

 lous on the sides; occasionally one cell is abortive and densely 

 appressed-pubescent, while the other is glabrous except for the 

 marginal cilia. Seed pilose, 4.2-4.7 mm. long. Aril 1.5-2 mm. 

 long, cloak-like, with lobulate or slightly lobed margin, rather 

 closely involving the seed. Chod.! Bull. Herb. Boiss. hi. 123
