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.
