5, included or barely exserted : filaments filiform or flattened, adnate to the corolla-tube. 
Ovary of 4 nearly distinct carpels. Nutlets 4, leathery, erect, wrinkled at maturity, 
laterally attached to the receptacle above their bases. LUNGWORT. 
1. Mertensia Virgínica (L.) DC. Perennial, glabrous, often glaucescent. Stems 
clustered, erect or ascending, 2-6 dm. tall, simple below the inflorescence : leaves 5-20 cm.

petioles, the upper sessile: panicles short, corymb-like : pedicels slender, 2-10 mm. long, 
curved : calyx 2-2.5 mm. long; lobes oblong or lanceolate, longer than the tube: corolla 
blue or rarely white, about 3 mm. long; tube narrowly funnelform, abruptly expanding 
into the limb, which is cup-shaped, lightly lobed, 1-1.5 cm. broad. 
On rich banks, Ontario to Minnesota, Georgia, Tennessee and Kansas. Spring. BLUEBELLS.

lobes 5, spreading, rounded, convolute. Stamens 5, included: filaments filiform, adnate 
to the corolla-tube. Ovary of 4 nearly distinct carpels. Nutlets 4, attached to the recep- 
tacle by their bases, glabrous or pubescent. FoRGET-ME-NOT. SCORPION-GRASS,
