 7213. Southern part of California; Fremont. Vallecita, California ; Thurher, Although not 

 agreeing in every respect with the description, these incomplete specimens probably belong to 

 Bentham's Beloperone Californica, wliicli Nees has not inaj^tly referred to his genus Jacobinia ; 

 but it surely belongs to Sericographis. It has the hairy lines, answering to the bases of the 

 suppressed stamens, weil-maiked. In one blossom there were three perfect stamens. The upper 

 lip of the corolla neatly shows the two long membranous lamella) which connive and form a 

 long channel containing in the bud the upper ])di.rt of the style ; a character which (Ersted has 

 added to the description of this and some related genera.'' A. Gray.

oblongis glabris sursura angustatis acutiusculis basi in petiolum atteuuatis floribus fasciculatis 



axillaribus terminalibusque sessilibus, tubo corollre elongato gracili. Read between Zuiii and 



Alta Sonora^ September; Schott. Plant apparently about a foot high; branches erect and 



slender. Leaves (including the petiole) 1^-2 inches long and 3-5 lines wide, entire, nearly 



smooth. Flowers fascicled in the uppermost axils. Calyx a little shorter than the lanceolate 



bracts and longer than the subulate bracteoles, the segments subulate. Corolla white?; border 



4"lobed, the three lower segments oblong, the upper segments bifid at the summit. Stamens 2, 



exserted ; anther-cells separate, one placed above the other^ obtuse at the summit, acute at the 



base. Ovary 4-dvuled. This seems to be distinct from any species of the genus described by 



Nees.

 MeeSj I. c. Santa Magdalena and Bacuachi, Sonora, September, October ; Thurher ^ Scltoit. (No. 



1465, Wright.) Our plant is a perennial, and some of the specimens seem to be even suffruticose, 

 but D. resupinata and thlaspoides are said to be annuals. The length of the peduncle is variable ; 



in Scholt's and Wright's specimens it is as long as tlie lateral divisions, but in Thiirher's 

 they are sometimes very short, and the middle division much elongated. The heads, also, 

 although mostly 1-flowered, are sometimes 2-flowered. The bracts are mostly broadly cordate, 

 but in Mr. Thurber's specimens from Bacuachi they are ovate and obovate.
