its teeth lanceolate. Corolla-tube slightly narrowed at mouth; limb 2-lipped; upper lip 
entire, arched; lower lip spreading, 3-lobed. Stamens 4, lower 2 longer; filaments of 
longer stamens 2-toothed at top, only | tooth anther-bearing; anthers 4. Nutlets ovoid,

PHYSOSTEGIA FALSE DRAGON-HEAD

or oblong, membraneous, |0-veined, equally 5-toothed. Corolla much exceeding the 
calyx, strongly 2-lipped; upper lip rounded, entire; lower lip spreading, 3-lobed, middle 
lobe commonly emarginate. Stamens 4, the lower 2 longer. Nutlets ovoid, 3-angled, 
smooth. (Gk. physa—a bladder, stege—a covering; referring to the inflated fruiting 
calyx.) |W. Cz FE. FP, parviflora Nutt. 
LAMIUM DEAD NETTLE

about 5-veined, 5-toothed. Corolla-tube usually exceeding the calyx (so ours); limb 
2-lipped; upper lip concave, erect, usually entire, narrowed at base; lower lip spreading, 
3-cleft, middle lobe emarginate, lateral ones sometimes with tooth-like appendage. Sta-
