viated axi!lar>' branches densely incurved-pilose above, sometimes with divergent 

 hairs, with or without some glands; leaves 3 to 8 pairs below inflorescence; lowest 

 leaves ovate, slender-petioled, crenate; the successively narrower middle and upper 

 leaves mostly oblong to linear-lanceolate and entire, narrowed to petioles to 1 cm. 

 long, punctate, minutely hoary, 2-6 cm. long, to 1.6 cm. broad; lowest internodes 

 1-2.5 cm. long; inflorescence a terminal raceme or leafy elongate panicle of 6- to 

 40-flowered racemes, all but lowest flowers in axils of much reduced foliaceous 

 linear-lanceolate bracts; pedicels short; calyx 2.5-3.5 mm. long in anthesis, 

 becoming 5-7 mm. long in fruit, puberulent; corolla 2-2.5 cm. long, purple-blue 

 and whitish or rarely rose-pink, the large lips subequal; the lower stamens inserted 

 about 8.5 mm. above base of tube; cocci subglobose, blackish, 1.2-1.6 mm. in 

 diameter, covered with rosulate flattish subimbricated papillae. 



Borders of woods, thickets and clearings, bogs, along streams, on seepage slopes 

 and about ponds in e. Tex., Apr.-June; from Fla. to Tex., n. to N.E., O., Ky. 

 and Mo. 



The var. hixpida Benth. has stems with numerous straighter and more divergent 

 hairs, and the transition from lower to median leaves more gradual than in var. 

 integrifolia. Plants with rose-pink flowers are designated as i.rhodantha Fern. 



2. Scutellaria galericulata L. Marsh skullcap. Fig. 660. 



Perennial with slender creeping rhizome and mostly subterranean slightly 

 thickened stolons; stems ascending, simple or forking, to 1 m. high, minutely 

 pilose on angles above with recurved hairs; leaves sessile or shortly petioled, 

 oblong-lanceolate to ovate-oblong, crenate, rounded to cordate at base, to 8 cm. 

 long and 3 cm. broad, often somewhat rugose, veiny, minutely pubescent (often 

 canescent) beneath with recurving hairs; flowers solitary in the axils of reduced 

 upper leaflike bracts to form 1 -sided interrupted racemes, very short-pedicelled; 

 calyx 3.5-4.5 (in fruit 5-6.5) mm. long, minutely pilose; corolla blue-violet with 

 whitish throat and tube, pilose, 15-25 mm. long, stamens inserted 8-10 mm. 

 above base of tube; cocci pale-olive, 1.5-2 mm. long, with broad low pebbling. 

 S. epilobiifolia A. Hamilt. 



Gravelly, sandy or rocky shores, in mud on edge of ponds and creeks, in 

 sloughs, wet meadows, marshes, swampy thickets in n. Panhandle of Tex., N.M. 

 (Colfax, Mora, Sandoval, San Juan and Taos cos.) and Ariz. (Apache, Navajo 

 and Coconino cos.), June-Aug.; from Nfld. and Lab. n.w. to Alas., s. to Del., 

 Pa., W.Va., O., Ind., HI., Mo., Kan., Tex., N.M., Ariz, and Calif. 



3. Scutellaria cardiophylla Engelm. & Gray. 



Annual, 4-6 dm. high, rather strict and stiffish, branching freely above the 

 middle, the branches ascendent and strict, clothed with recurved appressed hairs 

 (particularly along the angles), sometimes with spreading glandular hairs in the 

 lowermost parts as well; basal leaves soon deciduous; median leaves deltoid, lightly 

 cordate, 2-5 cm. long, crenate-dentate, the lower ones borne on petioles as long as 

 the blades, the uppermost subsessile and subentire. gradually diminished upward, 

 the upper surfaces of all glabrous, the lower surface hispidulous with spreading 

 hairs, their margins usually ciliate with longer hairs; flowers produced in the 

 upper parts of the plant in the axils of gradually diminished leaves, the pedicels 

 clothed as are the stems; flowering calyces retrorse-pubescent and ciliate on the 

 margins, the lower lip 4-4.5 mm. long at anthesis but 5-6 mm. long at maturity, 

 the scale about 3.5 mm. tall and concave; galea and tube 13-22 mm. long, the 

 tube pilose within, the lip glabrous; lower filaments seated 7-13 mm. above the 

 base of the tube; cocci black, shallowly papillate.
