Hispid Hedeoma. PI. 5 to ^ foot. 



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. 



XLVIII. MICROME'RIA (from /m-poe, mikros, small ; and 

 , meris, a part ; probably from the small parts of the 

 plants.) Benth. in bot. reg. vol. 15. lab. p. 368. Satureia and 

 Thymus species of Lin. and other authors. Sabbatia, Mcench. 

 meth. p. 386. but not of Pursh. Piperella, Presl, fl. sic. ? 

 without character. 



LIN. SYST. Didyndmia, Gymnospermia. Calyx tubular, 13, 

 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 Satureia 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. HESPEROTHY'MUS (from tvircpoe hesperos, the even- 

 ing ; and QvfioQ, 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.

 ceous, erect, small ; leaves sessile, oblong-linear, obtuse, quite
