Densely tufted and intricately branched, matted, hoary-pubescent, pale, 4'-8' high; branches stout, ascending. Leaves about 1" long, oval or oblong, densely imbricated and appressed; flowers sessile, or on rather stout pedicels less than 3" long, numerous, slightly smaller than those of the preceding species; sepals obtuse; stamens 9-18; capsules ovoid, glabrous, usually I-seeded.

3. LÈCHEA Kalm; L. Sp. Pl. 90. 1753.

Petals 3, ovate to linear, inconspicuous, persistent. Stamens 3-12. Stigmas 3, nearly sessile, laciniate, prominent when the plant is in flower. Capsule 3-valved, 3-celled, or by obliteration of the dissepiments I-celled, about 6-seeded. Embryo curved or spiral. [Named for Johan Leche, a Swedish botanist, died 1764.]

Outer sepals equalling or shorter than the inner.
Pod oblong; pedicels slender, 1"-2" long.
Pod globose; pedicels about 1/2" long.
Ascending, bushy-branched, tomentose-canescent.
Leaves of the basal shoots lanceolate or linear, usually more than 3 times as long as broad.
Stem-leaves narrowly linear; inner sepals 1-nerved.
Stem-leaves oblong-linear; inner sepals 3-nerved.
Plants green, more or less pubescent.
Pod obovoid, 1/2" in diameter; panicle-branches ascending or spreading.
Pod globose, about 1" in diameter; panicle-branches nearly erect, loosely flowered;
Pod oval, about 1/2" in diameter; panicle-branches erect-ascending, densely flowered;
