Treatment appears in FNA Volume 7. Treatment on page 64. Mentioned on page 29, 60.

Plants 0.01–1.5 m, sometimes clonal by layering or rhizomes. Largest medial blades hypostomatous, amphistomatous, or hemiamphistomatous, abaxial surface glaucous. Catkins from subterminal buds. Staminate flowers: filaments glabrous or hairy. Pistillate flowers: abaxial nectary sometimes present, then distinct, or connate to adaxial and forming a cup; ovary not glaucous, sparsely to very densely short-silky, hairs white or white and ferruginous, cylindrical or flattened.

Distribution

North America, Eurasia

Discussion

Species 4 (3 in the flora).

The branchlets in all members of sect. Chamaetia rarely elongate to produce late (neoformed) leaves. Flowering branchlets usually are not differentiated from vegetative branchlets and often have the same number of leaves.

Selected References
