exposure. I therefore place this variety where I did the 

 original specimen collected by me in 1880, No. 1716, at 

 Leeds, S. Utah, upon which the species of Koehne was 

 founded. This would seem to be ^ . -pallida var. arguta 

 Greene. 



All the numbers given above have acute leaflets, the 

 following have obtuse and rounded leafleis and are nearer 

 the type of A. Utahensis.

 west of St. George, Utah, 5200° alt., on rocky slopes.

PuRSHiA TRiDENTATA var. GLANDULOSA (Curran, BuL 

 Cal. Acad, i, 153). I agree with Mrs. Brandegee (Mrs. 

 Curran) that this is only a variety of P. tridentata. Hav- 

 ing examined all of Mr. Coville's specimens in the Na- 

 tional Herbarium I failed to find constant characters. 



POTENTILLA SABULOSA. IvESIA SABULOSA. 



No. 6032. Sept. II, 1894, head of the Sevier River 

 among pines, 8000° alt., in compact gravelly clay. 



This plant ranks next to P. Kingii, but very much re- 

 sembles Utahensis. Stems erect, 6-9' long, rather slender, 

 growing in patches much after the fashion of Arenaria 

 Kingii, and Fendleri; petals linear to oblanceolate, about 

 as long as the calyx lobes; accessory calyx lobes minute.
