Abronia angulata n. sp. Annual with the habit of A. 

 villosa Wat. Much branched from the root, stems stout and 

 succulent, whole plant very glandular-villous even to the flowers 

 except the glabrous and coriaceous leaf-blades; stems and pe- 

 tioles deeply sulcate when dry; nodes 2 to 4 inches' apart; stout 

 petioles rarely less than )/'> the blade; blades r to 2 inches long,, 

 cordate to truncate below, rounded above, ovate to broadly ob- 

 long, lighter below, upper leaves much reduced; stems floriferous 

 throughout except the lowest portions; peduncles short but 

 longer than the leaves, 1 to 3 inches long, slender in fruit, often 

 reflexed; bracts white, oval to broadly ovate, about half as long 

 as the flowers, acutish, 3 to 4 lines long, not reflexed; flowers 

 with slender greenish tube, about 2 lines wide at tip, white or 

 outer side tinged with pink; fruit 2 lines long, body oblanceolate 

 Y± line wide, wings but little contracted below, fully a line 

 wide at the produced, thin apex, the fruit in outline seems obcor- 

 date, glabrous except the ciliate wings. This seems to be in- 

 termediate between the cycloptera and fragrans sections, but 

 near to A. villosa. Darwin Mesa Argus Mts. Cal. 5000 ft. alt. on 

 drifting sand dunes May 11, 1897. 



Eriogonum Stokes^:, n. sp. Either a winter-annual or 

 short-lived perennial, proper stems woody, 3 to 4 inches long, 

 densely clothed with a multitude of densely short-woolly, thick, 

 obovate to rhombic-obovate leaves, with an abrupt apiculation 

 and tapering into a stout petiole half as long as the blade, the 

 whole 1 to \y 2 inches long, pubescence permanent; flowering stems 

 many, not slender, umbellately branched 4 to 6 inches above the 

 base into simple or compound racemes fully as long as peduncle, 

 floccose- woolly, leaves none on the stems above the root clusters; 

 bracts 3, 1 to 2 lines long, subulate, barely connate; involucres 

 sessile on the upper side of the rachis, barely angled, with short, 

 erect, triangular lobes about 2 lines long; flowers 25 to 30, on 

 filiform exserted pedicels, glabrous externally, white with green 

 midribs, oblong-obovate in the bud, with tapering winged base 

 nearly as long as the body and then jointed to the pedicel,, the
