Cult. The annual species, like other half hardy annuals, 
are reared on a hot-bed, and afterwards planted out into the 
open ground about the end of May. The shrubs should be 
grown in pots in light rich earth; and they will be readily in- 
creased by cuttings and seeds. 
XLVI. MICROMERIA (from puxpoc, mikros, small ; and 
peptc, meris, a part; probably from the small parts of the 
plants.) Benth, in bot. reg. vol. 15. lab. p. 368.—Saturéia and 
Thymus species of Lin. and other authors.—Sabbatia, Mcench, 
meth. p. 386. but not of Pursh.—Piperélla, Presl, fl, sic.? 
without character. 
Lin. syst. Didynàmia, Gymnospérmia. Calyx tubular, 18, 
rarely somewhat 15-nerved, 5-toothed ; teeth nearly equal, 
straight, or scarcely disposed into 2 lips; throat usually villous 
inside. Tube of corolla equal, straight, naked inside, usually 
shorter than the calyx; limb bilabiate : upper lip erect, flattish, 
entire or emarginate; lower lip spreading, with flat, nearly equal 
lobes, or the middle lobe is broadest, entire or emarginate. 
Stamens 4, didynamous: lower ones the longest, ascending, ap- 
proximating by pairs at the apex, rarely a little divergent ; fila- 
ments toothless; anthers free, 2-celled : connective usually 
thickened ; cells distinct, parallel, diverging, or a little divari- 
cate. Lobes of style sometimes equal, subulate, with minute, 
terminal stigmas: sometimes the superior lobe is very short, 
and the lower one elongated, recurved, and flattened, with a 
stigmatiferous margin. Achenia dry, smooth.—Undershrubs or 
herbs. Whorls axillary or spicate, rarely cyme-formed, subpa- 
nicled. Flowers generally small, purplish or white. This 
genus is nearly allied to Saturéia and Melissa; and differs from 
the first by the nervation of the calyx and stamens; and from 
the last chiefly in the calyx, which is less bilabiate. 
Sect. I. Hesperotuy'mus (from éozepoc hesperos, the even- 
ing; and Ovpoc, thymos, thyme; probably from their exhaling 
a stronger scent in the evening.) Benth, lab. p. 371. Flowers 
solitary, on axillary pedicels, 1-3 on both sides ; pedicels longer 
than the calyxes. Common peduncle wanting, rarely elongated. 
—American herbs, having the leaves usually crenated.
