Fic. 28, Flowers of plantain (Plan- 
tago lanceolata), six times natural 
size 
A, earlier stage, pistil mature, sta-

corolla; B, later stage, pistil with- 
ered, stamens mature 
ennial, from a very short rootstock. 
Leaves ovate to oval, strongly 5-9-

concave petiole, entire or toothed, 
smooth or slightly downy. Scape 
taller than the leaves, downy, spike 
densely flowered; bracts short, ovate. Flowers perfect. Stamens 4, 
projecting. Capsule ovoid, about twice the length of the calyx, 5-16- 
seeded; seeds angled and with a netted outer coat. Common in 
dooryards.* 
2. P. Rugelii Decaisne. Leaves as in P. major, but smaller and 
thinner. Spikes less dense, usually drawn out to a slender point. 
Capsule 4-10-seeded; seeds oval, the outer coat not netted. In fields, 
woods, and waste ground. 
3. P. lanceolata L. Rr Grass. Biennial or perennial; soft-hairy
