Leaves mostly basal, spreading, lyrate-pinnatifid, usually purple, 
stem-leaves small, sessile or short-petioled. Racemes many-flowered, 
whorls about 6-flowered. Calyx-teeth short on the upper lp, long 
and awl-shaped on the lower. Corolla blue or purple, the tube 
about 1 in. long, dilated upward. On dry soil.* 
2. S. officinalis, L. GARDEN SAGE. Stem shrubby, slender, much 
branched below, 1 ft. high. Leaves grayish-green, lance-oblong, cre- 
nate, wrinkled. Flowers in terminal spikes, whorls several-flowered. 
Corolla blue, upper lip strongly arched, about equaling the lower. 
Introduced from Europe and a common garden herb.* 
IX. THYMUS, L. 
Small, much-branched shrubs, very aromatic. Leaves small, 
entire, margins often rolled under. Whorls of flowers few- 
flowered, in loose or close spikes; bracts very small; flowers 
usually purple. Calyx ovoid, 2-lipped, upper lip 3-toothed, 
lower 2-cleft, woolly in the throat. Corolla slightly 2-lipped.

1, T. Serpyllum, L. Creerinc THyme. Smooth or hairy, stem 
prostrate, the flowering branches somewhat ascending. Leaves 3-3 
in. long, flat, ovate or obovate-lanceolate, obtuse. Flowers crowded 
in spikes at the end of the branches. Corolla rose-purple, }-3 in.
