Russelia (in honor of Alexander Russell). Scrophulariaceae. Shrubs with angled, usually slender and often pendulous branches, grown in the warmhouse for their showy flowers. Leaves opposite or verticillate, usually small, reduced to scales on the branches: fls. in bracteate dichotomous cymes, either laxly or densely many-fld., sometimes reduced to a single fl., red; calyx deeply 5-cleft or 5-parted, segms. strongly imbricate; corolla-tube cylindrical, limb somewhat 2-lipped, 5-cleft, the lobes all rounded; stamens 4, didynamous: caps. subglobose, septicidally dehiscent, valves 2-cleft. About 20 species, Mex. and Cent. Amer. A synopsis of Russelia by B. L. Robinson, with a key to the species, will be found in Proc. Amer. Acad. Arts. & Sci., vol. 35, No. 16, March, 1900. Russelias are of easy cultivation. R. juncea and its varieties make excellent basket-plants, being almost continuously in bloom. Propagated by cuttings.
