are short-oval and roughened by muriculate toothing of the reticula- 

 tions and some rugosity. The recent distribution of Curtiss, as P. 

 glandulosa, no. 2128* in his sets of United States plants, belongs to 

 it. Also Wright's no. lo78.

 ima, seminibus oblongis prioris, viscidula ; foliis ovalibus repando-

 spathulatis corolla parum brevioribus capsulam ovali-oblongam circa 

 20-spermam asquantibus ; stylo hirsuto apice brevissimoi bilobo. —

 1-2-pollicaribus cum petiolo percrasso aequilongo, superiorihus subses- 

 silibus ; spicis brevi-pcdunculatis saipius gemiuatis densifloris ; calycis 

 lobis lato-linearibus corollam campanulatam lin. 2-3 longara cajruleam 

 capsulamque subglobosam polyspermum asquautibus ; seminibus ovali- 

 oblongis semilineam longis. — Dry alkaline lakes, near Calico IMines, 

 Mohave Desert, May, 1882, S. B. & W. F. Parish. A most peculiar

 duplo longiore, plicis vix ullis ; capsula ovali-oblonga sepalis angusto- 

 spathulatis suba^qnilonga 12-14-sperma ; seminibus ovalibus favoso- 

 corrugatis. — Mountains of Lower California near the U. S. border, 

 Charles N. Orcutt. 



Mr. Orcutt likewise collected in Lower California a well-marked 

 and very viscid species of the EiUoca section, which was described 

 under an appropriate name ; but being informed that it was some 

 years ago named by Dr. Kellogg from specimens collected by Dr. 

 Veatch, and is about to be published in California, I leave it without 

 further notice.
