the oblong anthers: fruiting calyx equally but not conspicuously 

 10-angled, noticeably reticulate-veined, ovoid, with sunken base and 

 connivent lobes closing the orifice. 



Mesquite Well, southern Nevada, May 1, 1905, Goodding 2247. 



One might think of referring this to P. crassijolia Benth. were it not for charac- 

 ter of the fruiting calyx, or to P. muriculata Greene, if dealing with the vegetative 

 characters alone. 



Amphiachyris Fremontii spinosa, n. var. — Intricately and 

 divaricately branched, many of the branches naked and slenderly 

 spinose, floriferous twigs not surpassing the foliar ones; scabro-puber- 

 ulent on foliage and young twigs: leaves oblong to elliptic, acute at 



both ends, 5-12 

 3-toothed.

1904. 



Mr. Goodding again secured this species, this time at Cane Springs, Meadow 

 Valley Wash, Nevada. These specimens are in perfect accord with the type 

 collection, no. 662, Kernan, Nevada. 



Hymenoclea fasciculata patula, n. var. — Slender stems (7-io dm 



long) widely procumbent or drooping; branchlets assurgent from 

 the stems upon which they are uniformly placed, and not fasciculately 

 clustered at the ends; the very short floriferous twigs similarly dis- 

 tributed upon the branches, and the little glomerules of 3-5 heads 

 (staminate and pistillate) open racemosely or almost spicately arranged 

 upon the branches: involucral bracts of the staminate heads nearly 

 entire; those of the pistillate heads very broadly reniform. 



Moapa, Nevada, April 8, 1905, Goodding 2178. 



Baileya pleniradiata perennis, n. var.— Stems numerous, 

 crowded in a dense cluster on the crown of a large indurated root, 

 3-5 dm high, leafy almost to the summit.

and has a larger number of bracts (about 40) in the involucre and more disk- 

 flowers (60-75). As pointed out by Hall (Comp. S. Calif. 164), the original 

 B. multiradiata Han'. & Gray (Emory Report 144) is not the B. multiradiata 

 Gray of Syn. Fl. 1 : 318, but is the var. niidicaulis of that work.
