MINT FAMILY. 



457 



subeordate at base, mostly petioled; flowers in a dense cylindraeeoin 

 braetless or nearly bractless spike, 1 to 2 in. long: lowest whorls 

 rarely separate; calyx-teeth deltoid, mucronate. commonly equaling 

 the tube. 



Rather uncommon: West Berkeley; Tiburoo, and southward t<> 

 Monterey. 



2. S. albens Gray. Stems erect, strict. 2 t<» 5 ft. high, white- 

 tomentose; leaves ovate to lanceolate, obtuse or cordate at base, 

 mostly the very lowest short-petioled; whorls many-flowered, mostly 

 indistinct and spicate, only the lowest whorls, if any. somewhat 

 remote, the inflorescence 3 to !> in. long; calyces often somewhat 

 yellow-green, the teeth awn-pointed. 



Along rivulets or near springs in the dry inner Coast Ranges: 

 Knoxville Grade to Lower Lake; Livermore Pass; Pacheco Pass. 

 .1 uly-Aug. 



3. S. ajugoides Benth. Stems mostly erect, simple. 8 to 24 in. 

 tall; herbage densely soft-pubescent, sometimes giabrate; leaves 

 oblong, 1 to 2£ in. long, acute or obtuse below, petioled. the upper 

 sessile; one or two flower clusters below rather remote and in the 

 axils of upper ordinary leaves, the leaves above becoming bradt-likr 

 and the clusters less remote; calyx short-campanulate or turbinate, 

 very silky-villous, often concealing the teeth; hairy ring below 

 middle of corolla-tube very oblique, the tube slightly constricted 

 below. 



Everywhere common in low lands in the Coast Ranges and Sacra- 

 mento and San Joaquin Valleys. May- Aug. 



Var. stricta (S. stricta Greene). Small resin-glands abundant 

 beneath the short pubescence on the leaves; leaves thinnish, ovate- 

 lanceolate or oblong, 3 to 3£ in. long, only the uppermost sessile; 

 calyx-teeth erect or somewhat connivent around the tube of the 

 corolla; upper lip of corolla very short. — In the original diagnosis, 

 the lateral lobes of the lower lip are described as reduced to men- 

 teeth. In specimens from Knight's Valley, the original locality, 

 collected June 18, 1894, by Mr. Davy, the corolla is small but the 

 lateral lobes are not any smaller relatively to the middle lobes of the 

 lower lip than in the species. We discover, however, that the corolla 

 tube has no evident constriction and the ring of hairs is horizontal, 

 not oblique. 



Var. velutina (S. velutina Greene). Pubescence short and close; 

 leaves cordate-ovate; spike elongated, interrupted. — Suisun Marshes. 

 Oct. This variety forms a transition to the preceding species. 



4. S. bullata Benth. Stems simple from the base or branched 

 above, erect or ascending, 10 to 22 in. long; foliage densely or sparsely 

 hispid, the stems retrorsely hispid, especially on the angles: leave- 

 oblong-ovate, sometimes varying to elliptic, coarsely crenate. trun- 

 cate or subcordate at base, 1 to 2 or even 3$ in. long, the lower on 

 petioles 1 to 2 in. long; flowers about G in a whorl, the whorls rather 

 remote (mostly G to 12 lines apart): calyx turbinate or campanulate-
