26. HEDEOMA Pers. Syn. 2: 131. 1807. 
Annual or perennial, strongly aromatic and pungent herbs, with small entire or crenulate 
leaves, and small blue or purple flowers in axillary clusters, these crowded into terminal, 
leafy-bracted spikes or racemes. Calyx tubular, 13-nerved, villous in the throat, the mouth 
mostly contracted in fruit, gibbous on the lower side at the base, or nearly terete, 2-lipped, 
or nearly equally 5-toothed, the upper lip 3-toothed, the lower 2-cleft. Corolla-limb 2-lipped, 
the upper lip erect, entire, emarginate or 2-lobed, the lower spreading, 3-cleft. Perfect stamens 
2, ascending under the upper lip, their anthers 2-celled, the sacs divergent or divaricate. 
Sterile stamens (staminodia) 2, minute, or none, very rarely anther-bearing. Ovary deeply 
4-parted; style 2-cleft at the summit, glabrous. Nutlets ovoid, smooth. [Greek, sweet smell.] 
About 15 species, natives of America. Besides the following, some 8 others occur in the south-

Teeth of both lips of the calyx subulate; leaves entire. hee 
Calyx-teeth all nearly equal; annual. 2. H. hispida.
