GAILLARDIA (named in honour of M. Gaillard, a French patron of botany). ORD. Compositae. A genus of very ornamental hardy annual or perennial herbaceous plants, natives of North and extra-tropical South America. Flower-heads yellow or purple, 2in. across, single, and supported on naked stalks; ray-florets three to five-toothed, often two-coloured; receptacle furnished with filiform bristles between the florets. Leaves sometimes pinnatifid, but usually entire or obscurely toothed, lance-shaped and rough; the cauline ones sessile. There are about eight species, all thriving in a good light friable soil, in masses. Propagation may be effected by cuttings, in autumn or spring; also by division, in the latter season. In cold localities, the perennial species frequently die in winter; in this case, seeds should be sown on a mild hotbed, in February or March. The best method of propagating the annuals is by cuttings, which are readily obtainable, as these form far superior plants to those procured from seed. GAILLARDIA amblyodon (blunt-toothed).* fl.-heads terminal, peduncled; ray-florets deep blood-red, twelve to fourteen, spreading; limb cuneate-oblong, obtusely three-lobed; disk-florets short. October. l., radical ones sub-spathulate; cauline ones semi-amplexicaul, oblong, sub-acute, coarsely toothed beyond the middle, usually contracted below it. h. 2ft. to 3ft. Texas, 1873. Annual. (B. M. 6081.) GAILLARDIA aristata (awned).* fl.-heads yellow, with prominent exserted reddish styles in the disk, 1in. to 3in. across. Autumn. l. lanceolate, entire, or remotely toothed. h. 1 1/2ft. United States, 1812. Perennial. (B. M. 2940.) There are several very handsome varieties of this species; notably grandiflora (Gn., Dec. 13, 1884), and grandiflora maxima. GAILLARDIA pulchella (neat).* fl.-heads larger than those of the first-named species; ray-florets crimson, tipped with bright yellow. Autumn. l. coarsely and sparsely toothed. h. 2ft. to 3ft. Perennial. (B. M. 1602, under name of GAILLARDIA bicolor.) A new form, named Lorenziana, is very handsome and unique in appearance: the ray and disk-florets develop themselves into tubular funnel-shaped three to five-lobed florets, and form handsome flower-heads, which are admirably adapted for cutting. Another variety, nana, is a fine free-flowering form of good compact habit, and with large flowers, which are reddish-crimson, bordered with citron-yellow. GAILLARDIA pulchella picta (painted).* A form with somewhat succulent leaves, and the more or less subulate fimbrillae of the receptacle shorter and stouter. (B. M. 3368, under name of GAILLARDIA bicolor Drummondii.) The following are mere garden names for slightly-varying forms of the foregoing species: Bosselari, coronata, hybrida, Loiselli, Richardsoni, and Telemachi. GAILLARDIA pinnatifida is a species not often seen in cultivation.
