i. VERBASCUM [Tourn.] L. Sp. PL 177. 1753. 



Biennial or rarely perennial, mostly tall and erect herbs, with alternate dentate pinnatifid 

 or entire leaves, and rather large yellow purple red or white flowers, in terminal spikes, 

 racemes or panicles. Calyx deeply 5-cleft or 5-parted. Corolla flat-rotate or slightly con- 

 cave, S-lobed, the lobes a little unequal, the upper exterior, at least in the bud. Stamens 5, 

 inserted on the base of the corolla, unequal, all anther-bearing; filaments of the 3 upper 

 stamens, or of all 5, pilose; anther-sacs confluent into one. Ovules numerous; style dilated 

 and flattened at the summit. Capsule globose to oblong, septicidally 2-valved, many-seeded, 

 the valves usually 2-cleft at the apex. Seeds rugose, not winged. [The Latin name of the 

 great mullen; used by Pliny.] 



About 125 species, natives of the Old World. Besides the following, another is naturalized in 

 the western United States. Type species : Verbascum Thapsus L.

Leaves strongly decurrent on the stem. i. V. Thapsus. 



Leaves not decurrent, or but slightly so. 2.

1. Verbascum Thapsus L. Great Mullen 



Verbascum Thapsus L. Sp. PI. 177. 1753. 



Erect, stout, simple or with some erect 

 branches, densely woolly all over with 

 branched hairs; stem 2-y high, wing- 

 angled by the bases of the decurrent leaves. 

 Leaves oblong, thick, acute, narrowed at 

 the base, dentate or denticulate, 4'-l2' long, 

 the basal ones borne on margined petioles; 

 flowers yellow, 8"-i2" broad, sessile, nu- 

 merous in dense elongated spikes rarely 

 branched above ; stamens unequal, the three 

 upper shorter with white hairy filaments 

 and short anthers, the two lower glabrous 

 or nearly so with larger anthers ; capsule 

 about 3" high, slightly longer than the 

 woolly calyx.
