Fig. 2912

Hudsonia ericoides L. Mant. 1: 74. 1767.

Bushy-branched from the base, greenish, softly-pubescent throughout, 4'-7' high, the principal branches slender, ascending. Leaves subulate, 3"-4" long, somewhat spreading, densely imbricated on the younger branches, more scattered on the older ones; pedicels very slender, 5"-8" long; flowers numerous, about 4" broad; sepals 2"-3" long, acutish; stamens 12-18; capsule oblong, slightly pubescent; seeds about 3.

In dry sandy soil, especially in pine-barrens, mainly near the coast, Newfoundland to New York and Virginia. Field-pine. Poverty-grass. American heath. May-June.

3. LÈCHEA Kalm; L. Sp. Pl. 90. 1753.

Perennial branching herbs, often woody at the base, with small entire leaves and minute panicled greenish or purplish flowers. Sepals 5, the 2 outer smaller and narrower. 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.]
