Lophanthus (Greek, crested flower; application not apparent). Labiatae. As defined by Briquet in Engler and Prantl's "Naturlichen Pflanzenfamilien," this genus comprises 2 Asian species. They are erect herbs with dentate lvs.and axillary clusters of blue or bluish fls. L. chinensis, Benth. (Hyssopus Lophan- thus, Linn.), from N. China and Siberia is sometimes planted, although apparently not in the trade. It is a nepeta-like plant, 1-1 ½ ft. high, with aromatic foliage, ovate lvs..., and blue fls. in 3-5-fld. cyme-clusters: blooms midsummer to autumn, and useful in the alpine garden.

The few N. American species formerly held under this name are now included under Agastache. Two of them have been offered by dealers in native plants, but they are scarcely horticultural subjects, although useful for the wild garden. These are: Agastache Foeniculum, Kuntze (L. anisatus, Benth.). Giant Hyssop. Height 2-5 ft.: lvs.ovate, anise-scented when crushed, white beneath: fls. blue; calyx-teeth tinged purple or violet. July, Aug. Prairies, Wis., to Rockies. A. scrophulariaefolia, Kuntze (L. scrophulariaefolius, Benth.). Height 4-6 it.: lvs.not anise-scented, not white beneath: fls. dull purplish; calyx-teeth whitish. Borders of thickets, N. Y. to Wis. and N. C.
