 base, obtuse, crenate, short-petioled, tomentulose-canescent, as are the branchlets : bract- 

 like floral leaves ovate, acuminate, membranaceous, glabrous above, apparently persistent, 

 longer than the interruptedly spicate flowers : these several in each cluster : calyx campan- 

 ulate, densely lanate with white dendritic-branched hairs ; upper lip 3-toothed, lower 2- 

 cleft, equalling the tube of the sliort and small (blue ? ) sliglitly dendritic-pubescent 

 corolla : upper lip of the latter emarginate ; middle lobe of the lower ample, 3-lobed, with

 (4 to 12 lines long) : flowers in short and rather dense simple racemes and in axils of upper 

 ordinary leaves, 4 lines long: calyx twice the length of the pedicel, in flower 2 or barely 3 

 and in fruit 4 or 5 lines long, then pendulous ; narrow tube striate-nerved ; its 3 lobes

 S. PLATVciiEiLA, Gray, Proc. Am. Acad. viii. 292, from Carmen Island in the Gulf of

 pilose-annulate : anterior portion of the connectives deflexed, abruptly dilated
