or rarely subcordate base, coarsely and irregularly serrate, on slender petioles ; upper lan- 

 ceolate or linear-lanceolate, sometimes entire ; floral subulate or ovate-lanceolate, mostly 

 caducous : spiciform inflorescence on a long naked peduncle, interrupted, of densely many- 

 flowered clusters, finely and the calyx very densely and softly white-tomentose (often 

 tinged with violet) ; the latter oblong-cylindraceous and in age striate-sulcate, as it were 

 truncate ; the teeth 3, very broad and obtuse, exceedingly short : lower lip of the violet- 

 blue corolla with middle division obeordate-two-lobed. — Lab. 274; Braun in Bot.Zeit.

S. aztirea, Lam. Glabrous or puberulent : lower leaves lanceolate or oblong, obtuse, 

 denticulate overrate, tapering into a slight petiole ; upper narrower, often linear, entire ; 

 floral or bracts subulate, somewhat persistent : spiciform inflorescence looser, more inter- 

 rupted, and fewer flowers in the clusters, sometimes thyrsoidal or paniculate-branched : 

 pedicels short : calyx oblong-campanulate, usually minutely puberulent, obscurely bila- 

 biate ; the very broad and obtuse upper lip and the two similar but acutish lobes of the 2-

 appressed teeth or nearly entire : the inconspicuous floral ones lanceolate or subulate, 

 somewhat persistent, seldom exceeding the pedicels : calyx minutely hairy on the nerves, 

 deeply bilabiate ; its lower lip 2-clef t, the teeth ovate and mucronate-acute : corolla small 

 (4 lines long), little exceeding the calyx, its lower lip little prolonged : lower fork of the con-
