4. Stachys lythroides Small. Perennial, deep green. Stem 4-9 dm. tall, sparingly 
hirsute, usually branched above: leaf-blades broadly linear or oblong-linear, 1.5-6 cm.

flowered : pedicels very short: calyx 6-7 mm. long; tube sparingly pubescent, becoming 
ribbed ; lobes lanceolate, somewhat shorter than the tube, barely subulate-tipped, ciliate : 
corolla purplish, 1 em. long. 
In sandy soil, near Tallahassee, Florida. Summer. 
5. Stachys ambigua (A. Gray) Britton. Perennial, hirsute. Stems erect, 3-10 dm.

ripted : bracts lanceolate, rather blunt-pointed : pedicels very short or nearly wanting: calyx 
6-8 mm. long, bristly ; lobes lanceolate, slightly subulate-tipped, as long as the tube or 
shorter, ciliate: corolla light purple, about 1 cm. long; tube surpassing the calyx, the 
lower lip as long as the tube, drooping, the upper lip concave, pubescent on the back: 
filaments pubescent: nutlets over 2 mm. long, granular. 
In moist sandy soil, New Jersey to Illinois and Georgia. Summer. 
6. Stachys Nuttallii Shuttlw. Perennial, conspicuously hirsute. Stems erect, 4-11 
dm. tall, simple: leaf-blades oblong or oblong-lanceolate, 5-10 em. long, acuminate, ser- 
rate-dentate, rounded or truncate at the base ; petioles 0.5-1 em. long, hirsute: spikes in- 
terrupted : bract surpassing the calyx, the upper ones with 3 tooth-like lobes : calyx 5 mm. 
long, hirsute ; tube campanulate ; lobes triangular-lanceolate, acuminate, 4 as long as the 
tube: corolla purple, 1 cm. long ; tube saccate about the middle, surpassing the calyx, the
