Ertogonum PARisnii. Of the same group, and resembling the last 

 in its foliage, glaucous, somewhat viscid witli mostly stipitate glands, 

 the ^ or 3 stems very diffusely branched above the first node, about a 

 span high: pedicels very slender, spreading, 1 to 3 lines long: invo- 

 lucres turbinate-campanulate, ^ of a line long or less : flowers very 

 small (J line long), red, minutely pubescent, the outer segments oblong- 

 lanceolate, acute, the inner broadly oblong-spatulate and shortly apicu- 

 late. — Collected in the San Bernardino Mountains, also by the Paribh 

 Brothers, in August, 1881. 



Eriogonom (Oregoxium) delicatulum. Of the § Corymbosa, 

 annual, very slender, low (3 to 5 inches high), glabrous above the 

 base : leaves radical, tomentose, round to oblong, 1 to 3 lines long, 

 with slender petioles : involucres narrowly turbinate, obscurely nerved, 

 a line long: flowers yellow, very small: akene soon exserted, a half 

 longer than the perianth. — In the Mohave Desert ; Dr. C. C. Parry, 

 1881. Resembling E. Muhavense, but smaller and more slender, 

 with narrower and less sti'ongly nerved involucres, and the akenes 

 exserted. 



Eriogonum molestum. Resembling E. virgatum, slender, gla- 

 brous excepting the leaves, 1 to 3 feet high : leaves all radical, reni- 

 form to cordate or rounded, densely white-tomentose at least beneath, 

 about an inch broad : involucres few and distant, rarely 2 or 3 together, 

 2 to 3 lines long : flowers white or pinkish. — Apparently frequent in 

 the mountains of Southern California, from Los Angeles County to 

 San Diego ; collected by Palmer, D. Cleveland, Parish Brothers, 

 Rev. J. C. Xevin, &c. 



Chorizaxthe cdspidata. Prostrate, villous-pubescent, with leafy 

 bracts : leaves narrowly oblanceolate, an inch long or less : floral 

 bracts acerose: involucres numerous, loosely cymosely clustered, a line 

 long, 6-toothed, without scarious margins, the alternate teeth shorter, 

 and all armed with hooked awns : flower nearly sessile, villous, 

 pinkish ; lobes oblong, nearly equal, acutish, strongly nerved and the 

 nerve excurrent as a short cusp. — Near San Francisco ; Marcus E. 

 Jones, 1881 (n. 238G). Allied to C. Parryi. 



CoRALLORHizA Arizoxica. Stem stout (li feet high), with 6 to 

 8 short sheathing leaf-scales, 10-lo-flovvered : flowers large, spurless 

 and scarcely at all gibbous, the sepals and petals (6 to 8 lines long) 

 several-nerved ; lip dilated and strongly nerved, with 5 prominent 

 ridges down the centre, 3-lobed above, the middle lobe undulate on 

 the margin and somewhat cucullate : column a third shorter than the 

 sepals, narrowly margined : capsule 6 to 8 lines long, narrowed to a
