Gi. HEDERACEA L. Sp 578. (Grounp Ivy.) Pubescent perennial: stems 
creeping, 6-18 inches long, the branches ascending : leaves nearly orbicular 
or reniform, cordate at base, 6-18 lines in diameter, green both sides, 
coarsely crenate: clusters few-flowered: bractlets shorter than the calyx, 
subulate: calyx puberulent, its teeth acute or lanceolate-acuminate, about 
one-third as long as the tube: corolla-tube 2-3 times as long as the calyx: 
upper pair of stamens much longer than the lower pair. In waste places,

14 DRACOCEPHALUM L, Sp. 594. 
Herbs with dentate incised or entire leaves and blue or purple 
flowers in axillary and terminal bracted clusters. Calyx tubular, 
15-nerved, straight or incurved, 5-toothed, the upper teeth much 
longer than the others, or bilabiate with the 3 upper teeth more 
or less united. Corolla expanded above, its limb bilabiate: upper 
lip erect, emarginate, the lower spreading, 3-lobed, the middle 
lobe largest and sometimes 2-cleft. Stamens 4, all antheriferous, 
the upper pair longest: anthers 2-celled, the cells divaricate. 
Nutlets ovoid, smooth. , N 
D. parviflorum Nutt. Gen. ii, 35. A somewhat pubescent annual or

at the apex, rounded or narrowed at base, thin, 1-3 inches long, all slender-. 
petioled : flowers numerous, in dense terminal spikes, and sometimes also 
in the upper axils: bracts ovate tooblong, pectinate with awn-pointed 
teeth, shorter than or equalling the calyx: pedicels 1-2 lines long: upper 
teeth of the calyx ovate-oblong, longer than the narrow lower and lateral 
ones, all acuminate: corolla light biue, scarcely longer than the calyx. In 
dry rocky or gravelly soil, Alaska to Idaho and New York. 
Tribe 5 Scutellariex Benth. in DC. Prodr. xii, 407. Herbage 
bitterish, little or not at all aromatic, Calyx bilabiate, closed in

lobes more connected with the galeate wpper lip: lower lip therefore of
