* I here append the characters of an interesting addition to a chiefly Eastern 

 North American genus, viz. : — 



Petalostemon Searlsi^e, n. sp. : perennis ? prseter spicara glaberriraus ; foliis 

 5 - 7-foliolatis cum caule ramisve simplicibus grosse glandulosis ; foliolis oblongo- 

 linearibus obtusis vel retusis crassiusculis ; spica longiuscule pedunculata cylin- 

 drica compacta ; bracteis ovatis membranaceis pauci-glandulosis in acumen caudi- 

 forme calycem adaquantum productis sericeo-ciliatis deciduis; calycis dentibus 

 attenuato-subulatis mollissime villosis tubo minus pubescente a?quilongis ; petalis 

 roseo-purpureis prseter vexillum deltoideo-cordatum angusto-oblongis. — The only 

 other species found west of the Mississippi Valley is the P. exile of Wright's col- 

 lection, from Arizona. This is from a similar region farther north ; viz., from 

 the Pahranagat Mountains in southeastern Nevada (about 400 miles southwest of 

 Salt Lake), where it was discovered by Miss Searls. It was one of an extremely 

 interesting collection made by this young lady in the vicinity of the Pahranagat 

 mines (which she visited in company^with her father), and entrusted to me by Pro- 

 fessor Marcy of Evanston, 111. A lady who braves the hardships of a journey to 

 6uch a remote and inhospitable district, and has the sense and spirit to make a col- 

 lection of plants in a place far out of the track of any botanist, well deserves to 

 have her name perpetuated in the annals of botany. I give it accordingly with 

 much satisfaction to one of the two entirely new plants of the collection. 



For others, see succeeding notes, e. g. CEnotkera, Chmnactis, Pentstemon, &c.
