Collinsonia
(named in honour of Peter Collinson, F.R.S., a well-known patron of science and correspondent of Linnaeus; he first introduced this and a host of other plants to English gardens). ORD. Labiatoe. Strongscented, rather coarse-growing, hardy herbaceous plants or shrubs. Flowers pedicellate, solitary; pedicels opposite, disposed in simple, but usually paniculately-branched, racemes; corolla exserted, sub-campanulate. They grow well in common garden soil, but prefer sandy peat, and a moist situation. Propagated readily by dividing the roots, in spring. C. anisata (Anise-scented).* fl. pale yellow; panicle dense. September. l. broad-ovate, a little toothed, roundly truncate at the base, wrinkled, pubescent on the nerves beneath, and on the stems, which are a little branched. h. 2ft. to 3ft. South United States, 1806. This species requires protection from severe frosts. (B. M. 1213.) C. Canadensis (Canadian). fl., corolla yellow, four times longer than the calyx; panicles elongated, loose, many-flowered. August. l. broad-ovate, acuminate, rounded at the base, sub-cordate, glabrous. Stems branched, glabrous, or a little downy. h. 1ft. to 2ft. North America, 1734. This hardy perennial has a peculiar scent, which is agreeable, but very strong.
