Cotyledon Oregonensis. Flowering stems 6 to 10 inches high, 

 from a running rootstock, tlie rosulate basal leaves spatulate, obtuse, 

 8 to 15 lines long; cauline leaves oblong-spatulate, 6 lines long or 

 less: peduncles axillary along the upper stem, 1 to 1 inch long, bear- 

 ing short simple or compound few-flowered racemes ; pedicels a line 

 or two long, with small bractlets : sepals deltoid, short ; petals pale 

 yellow, united to below the middle, 4 lines long : stamens slightly 

 shorter. — Found in the Cascade Mountains, Northern Oregon, by 

 J. & T. J. Howell, June, 1880. A peculiar species, both in its habitat 

 and in its inflorescence. 



CExOTiiERA (Cuylismia) hetekochroma. Annual, erect (a foot 

 high), sparingly branched above, glandular-pubescent thi-oughout : 

 leaves ovate-lanceolate (an inch long or less), dentate or nearly 

 entire, the villous pubescence less glandular ; floral bracts minute : 

 flowers in nearly strict racemes, erect on short slender pedicels , 

 calyx-tube narrowly obconical {l^ lines long), about equalling the 

 lobes ; petals purple with whitish base : capsule clavate, 4 lines long : 

 seeds oblong-obovate. — At Candelaria, Esmeralda County, Nevada ; 

 W. II. Shockley, 1881. 



CEnothera (Sph^ro stigma) refracta. Annual, erect, diffusely 

 branching, about a foot high, somewhat glandular-puberulent : leaves 

 narrowly lanceolate to linear, slightly sinuate-toothed, 1 or 2 inches 

 long : flowers sessile, axillary and spicate, the upper approximate and 

 nodding in bud : calyx-tube narrowly obconic, 2 to 2| lines long ; 

 petals pale-yellow, 2 or 3 lines long : stigma large and spherical, ex- 

 serted : capsule slender, nearly terete, striate, straight or somewhat 

 curved, 10 to 18 lines long, at length usually abruptly reflexed : seeds 

 linear, nearly white. — Southern California to Southern Utah, from 

 several collectors. First collected by Dr. Bigelow near the Colorado 

 ( (E. dentata, Torr. in Pacif. R. Rep. 4. 87, in part), and distributed as 

 (E. strigidosa, var., in Palmer's collection of 1876 in Arizona and S. 

 Utah (n. 1G5). It has also been mistaken for (E. alyssoides, and is in 

 some respects intermediate between the two species. 



EcniNOCYSTis ( ?) PARViFLORA. Stem very slender, glabrous : 

 leaves scabrous above, an inch long or less, cordate, acute, deeply 3- 

 lobed, the lateral lobes somewhat quadrate : tendrils not branched : 

 flowers numerous, minute, white, in very slender sessile panicled 

 racemes, the pistillate solitary in the axils of the panicle and shortly 

 pedicellate ; corolla rotate, deeply 5-cleft, a line wide : anthers 3, 

 nearly sessile, united, recurved : ovary semi-obovate, with a long fili- 

 form beak (the whole 3 lines long), compressed, sparingly echiuate,
