(after Sir Robert Colquhoun). Labiatae. Tender plants with dense whorls of gaping flowers an inch long or more, colored scarlet and yellow. Erect or twining shrubs, woolly in all parts when young: leaves large, crenate: whorls few-flowered, axillary or crowded into a terminal spike or raceme; corolla-tube incurved, the throat inflated. - Two Asian species. Propogation by cuttings of growing tips, in sandy soil, under glass in summer.
Wall. Tall climber, with very long branches, 8-10 ft.: leaves stalked, ovate-acuminate, 3-5 in. long, crenate, dark green above, roughish, typically with scarcely any woolliness except when young: corolla twice as long as the calyx. B.M. 4514. - C. tomentosa, Houll., is probably identical. The dense woolliness is perhaps temporary. R.H. 1873:130 shows a handsome terminal spike in addition to axillary clusters, containing about 20 flowers - Apparently not advertised, but probably as worthy as the next.
Wall. Very smilar to C. coccinea, except that it is a low-growing, erect plant, and more densely and permanently woolly on the stem, calyx and under side of leaves, which are elliptic or elliptic-ovate and cordate. - Cult, outdoors at Santa Barbara, Calif., where it may be used for the wild garden as it is perfectly hardy. Not of much horticultural value.
