17. GALEOPSIS L. Sp. Pl. 579. 1753. 
Erect annual branching herbs, with broad or narrow leaves, and rather small yellow red 
purple or mottled verticillate-clustered flowers in the upper axils, or forming terminal dense 
or interrupted spikes. Calyx campanulate or tubular-campanulate, 5-10-nerved, 5-toothed, 
the teeth nearly equal, spinulose. Corolla-tube narrow, the throat expanded, the limb strongly 
2-lipped; upper lip erect, concave, entire; lower lip spreading, 3-cleft, the middle lobe obcor- 
date or emarginate. Stamens 4, didynamous, ascending under the upper lip of the corolla, 
the anterior pair the longer; anthers 2-celled, the sacs transversely 2-valved, the inner valve 
ciliate, the outer smooth, larger. Ovary deeply 4-parted; style 2-cleft at the summit. Nut- 
lets ovoid, slightly flattened, smooth. [Greek, weasel-like.] 
About 6 species, natives of Europe and Asia. Type species: Galeopsis Tetrahit L. 
Plant puberulent; leaves linear to ovate-lanceolate. 1. G. Ladanum.

Nettle. Ironwort. Fig. 3605. 
Galeopsis Ladanum L. Sp. Pl. 579. 1753. 
Puberulent, sometimes glandular above; stem 
slender, erect, much branched, 6-18’ high, the
