half as wide below: filaments flattish: pods stout, spreading 

 almost at right angles or somewhat ascending, 4-6cm. long, 

 nearly 3mm. wide, the stout ver}^ short style point only imm. 

 long; pedicels icm. long, half the thickness of the pods. 



No. 6650, collected on the sand hills be^^ond Seaside, near 

 Del Monte, Monterey county, California, May i, 1903. In size 

 and color of the flowers it is like E. grandiflorum^ which is 

 found at Point Pinos, onl}' a short distance beyond, but in other 

 respects it is very different. In case the name Cheiranthits is 

 the proper one for the genus, this species may be known as 

 Cheiranthus ammophilus.

Apparently perennial: stems 3-7 dm. high, simple, or the 

 larger plants a little branched, bright green or purplish, more 

 or less pubescent with appressed hairs: basal leaves numerous, 

 oblong-spatulate, 4-5cm. long, including the slender petiole of 

 2-2. 5cm., about 8mm. wide, inconspicuously runcinate-toothed, 

 sparingly appressed pubescent on both sides, the apex rounded, 

 shortly apiculate; stem leaves scattered, gradually becoming 

 smaller and sessile or nearly so, linear-lanceolate, acute, entire: 

 flowers bright yellow: calyx icm. long, appressed pubescent, the 

 oblong lobes barely acutish: petals about 17mm. long, the ovate 

 blade 6mm. long; 5mm. wide: pods rather slender, ascending, 

 about idm. long, 2mm. wide, beaked by the evident (5-7mm.) 

 style: seeds 2mm. long, green, the one side edged with a thick 

 yellowish rim. 



No. 6956, collected July 17, 1903, near the base of the ridge 

 skirting the south side of Donner Lake, Nevada county, Califor- 

 nia, altitude 6000 feet. It grew on a wooded northerly slope 

 among rocks. The pedicels, which are less than half the thick- 

 ness of the pods, are icm. or more in length, ascend at an angle 

 of about forty-five degrees, and the pod itself is commonly erect. 

 It is one of the aggregates of E. asperitm^ and perhaps ma}^ ha"\'e 

 to be known as Cheiranthus Nevadensis.
