mens from Santa Margarita Island are much taller, with 

 narrower and more scattered leaves. — Magdalena and Santa 

 Margarita Islands. 



PoLYGALA DESERTORUM. Stems erect, branched from a 

 somewhat woody base, slightly pubescent, a foot high: 

 leaves linear-lanceolate, 18 mm. long, tapering to the base, 

 becoming bract-like above: flowers upon pedicels 2-4 mm. 

 long, soon reflexed: sepals glabrous, all purple, the outer 

 round, saccate at base, 4 mm. long, the lateral oblong, 

 mucronate, 5 mm. long: upper petals pubescent near the 

 base, nearly as long as the keel, connected nearly half their 

 length, purple; keel rugose-thickened, yellow; crest re- 

 curved, prominent: style tortuous, recurved, hollow, some- 

 what two lobed; ovary stipitate: capsule elliptical, emarg- 

 inate: seed densely hairy, the short caruncle with two small 

 wings not J the length of the seed. — Growing upon the plain 

 near Agua Dulce. Its persistent purple sepals make this a 

 handsome species. 



PoLYGALA APOPETALA, (Plate III.) Frutescent, 2-3 feet 

 high, with straight, slender, grayish-pubescent branches: 

 leaves lanceolate, entire, obtuse, attenuate to a short petiole, 

 alternate, remote, nearly glabrous: flowers large, pink, on 

 slender pedicels a half inch or more in length : sepals 4, the 

 upper and lower small, equal, cymbiform, with ciliate mar- 

 gins, the lateral very large, nearly orbicular: petals 5, all 

 separate, the two upper strap-shaped, revolute outward, | 

 as long as the keel, the lateral ones pointed, less than half 

 as long, lying on the stamineal tube and with it embraced 

 by the large unguiculate cymbiform keel, which is open by 

 the whole of the upper and a part of the lower edge, and 

 not cristate nor appendaged: stamens 8, monadelphous for 

 half their length, united with the petals only at the base, 

 anthers often apiculate, sometimes by a process as long as 

 the anther, opening by a transverse notch near the middle: 

 ovary sessile; style curved, nearly simple, pubescent on its
