numerous. — Yellow. If. May — June. Dry soils, Geo. and Car. 6 — 

 12 inches. 



This is a beautiful genus of flowering plants, of which Europe produces more than 

 forty species, while North America produces only rive. We know not that our in- 

 digenous species are cultivated, but well deserve it, beyond that of many imported 

 plants. 



Genus II.— LE'CHEA. L. 3—3. 

 (In honor of Leche, a Swedish naturalist.) 



Sepals 3, with two exterior, narrow, and bract-like. Petals 

 3, minute, lanceolate. Stamens 3 — 12. Stiff mas 3, on a short, 

 somewhat united style, fimbriate. Capsule 3-valved, appa- 

 rently 3-celled, with roundish placentae, nearly as broad as the 

 valves, about 2-seeded. Perennial herbs. 



1. L. ma'jor, (Mich.) Stem herbaceous, branching, scabrous; young

Var. tenufo'lia. Stem decumbent and assurgent, very much branch- 

 ed, somewhat hairy. Leaves subulate, linear. Flowers solitary, at the 

 extremities of the branches. — White. If. Sandy soils, in middle Car. 

 6 — 18 inches. 



3. L. thymifo'lia, (Mich.) Stem frutescent, decumbent at the base, 

 much branched above, hoary-villous. Leaves linear, acute, numerous; 

 those of the procumbent radical branches small, imbricate, elliptical. 

 Flowers 2 — 6, at the extremities of the branches, in leafy panicles. 

 Calyx tomentose. — White. IX. Sandy soils. May — Aug. 10—15 

 inches. 



Order XIX.— HYPERICA'CE^E. • 



Sepals 4 — 5, cohering at the base, or distinct, persistent, un- 

 equal ; estivation imbricate. Petals hypogynous, as many as

 hypogynous, usually very numerous, polydelphous, usually in 

 three parcels. Anthers versatile, introrse. • Ovary composed of 

 2 — 5 united carpels. Styles several, persistent. Capsule with
