thick, entire, sessile, acute. Flowers 2’ in length, 2—4 together at top of the 
stem and a few solitary ones in the axils of the upper leaves. Corolla blue. 
Calyx segments 6—9” long, acute, distant. Aug., Sept. 
B. rubricaulis. (G. rubricaulis. Schw.) Lvs. ovate-lanceolate; folds of the

St. 4angled, branching; Jvs. ovate-lanceolate, acute, 3-veined ; fis. termi- 
nai and axillary, about in 5s, pedicellate; co/™ tubular-campanulate, in 5, 
lanceolate, setaceously acuminate segments; cal. very short—@) Woods and 
pastures. Stem a foot high, smooth, generally branched. Leaves 3—5-veined, 
half-clasping, acute, smooth. Flowers small, on pedicels half an inch in
