100 LABIATS. (MINT FAMILY.) 
times sparingly toothed; bracts linear, acute; lower lobes of the calyx much longer than 
the others. 
2. P. parviflora, Benth. Smaller; bracts mostly obtuse; corolla 5 or 6 lines long. 
* * Upper stamens sterile; style sparingly hairy, its lobes very unequal; flowers barely 2 lines 
Ong. 
3. P. serpylloides, Gr. Stems 3 to 6 inches high; leaves obovate-oval or spatulate, 
2 or 3 lines long; lower flowers remote and often solitary; the upper usually interruptedly 
spicate. 
7. SPHACELE, Benth. 
Calyx thin, membranaceous and reticulated. Corolla with 5 broad, rather erect lobes, 
the lower one longest. Anther cells diverging. Somewhat shrubby, veiny-leaved. 
S. calycina, Benth. Villous-pubescent or tomentose, leafy, 2 to 5 ft. high; leaves 2 
to 4 inches long, ovate or oblong crenate or serrate, or almost entire; the floral, ovate- 
lanceolate, sessile; flowers an inch long, mostly solitary in the upper axils, purplish or 
lead-color. 
8. SALVIA, L. SacE. 
Calyx bilabiate. Corolla deeply 2-lipped, the upper lip erect, straight or falcate, 
2-lobed, the lower spreading or drooping, its middle lobe sometimes notched or obcor- 
date. In our species the upper lip of the calyx is longer than the lower, 3-2-toothed; the 
lower 2-parted; the teeth spinulose; corolla ringent. 
1, S&S. carduacea, Benth. White-woolly with cobwebby hairs; stems nearly naked, 
surrounded at the base with thistle-like leaves; head-like false whorls 1 to 4, an inch or 
more in diameter, about equaling the involucre of spiny-toothed bracts; corolla 10 to 12 
lines long, blue or purple. 
2. S. Columbariz, Benth. (Cuis.) Soft pubescent; flower whorls 1 or 2; involu- 
crate bracts, sometimes purplish; corolla 3 or 4 lines long, blue; leaves not spinescent. 
9. AUDIBERTIA, Benth. 
Sufficiently distinguished from Salvia in the synopsis.—Mostly hoary perennials, her- 
baceous or shrubby; with rugose-veiny, crenulate, sage-like leaves, and densely capitate- 
glomerate flowers. 
1. A. grandiflora, Benth. Stems 1 to 3 feet high from a somewhat woody base; 
lower leaves 3 to 8 inches long; floral ones broadly ovate and membranaceous; corolla an 
inch and a half long; purple-crimson; stamens much exserted. 
2. A, humilis, Benth. A span high, cespitose; leaves mainly radical; spike of 3 or 
4 small, sessile, head-like clusters; corolla half an inch long or less, bluish purple. 
3. A. stachyoides, Benth. Shrubby, 3 to 8 feet high; style and stamens little 
exserted; coru:la about as the last.
