(named for Escallon, a Spanish traveler in South America). Saxifragaceae. Mainly evergreen shrubs or small trees, widely dispersed in South America, especially in the mountains.
Leaves alternate, glandular-serrate (rarely entire): flowers strongly odorous, white or of a pink or red color, in terminal racemes or panicles, or axillary; calyx-lobes 5; petals 5; stamens 5; style simple, the stigma obscurely 4-5-lobed and peltate, or 2-lobed and reni-form or peltate. Noteworthy in the genus are the glands, stalked or not, which may occur almost anywhere on the plant. Leaves often with resinous dots on one or both surfaces. - About 45 or 50 species, a number of which have been introduced in the S., and in Calif. They are of easy culture; rapid growers; and often artificially trained as vines. Several will probably prove half-hardy as far north as N. Y.
A. Leaves large, hairy, especially below, or in one variety glabrous but very shiny.
Pers. Shrub: leaves very thick, oval or elliptic, obtuse, serrate, rough-hairy below, with scattered hairs above: flowers white, in long densely flowered terminal racemes; stigma distinctly 2 - lobed, reniform: fruit a glandular -warty caps.: branches hairy. variety glabra, Engler. Differs from the species in being almost or quite glabrous. Handsomer than the type. Not in cultivation in this country.
AA. Leaves glabrous or nearly so.
b. Flowers red or pink.
Pers. variety glabriuscula, Hook. & Arn. (E. rubra of many authors). Dainty flowered shrub, with numerous stalked glands: leaves ovate, often deltoid-ovate, acute, finely and irregularly doubly - serrate, glabrous, with brown resinous dots below, rather small: flowers red, tubular, borne in 2's or 3's (or rarely singly) on lateral pedicels, grouped near the ends of the branches; calyx densely glandular; petals long-clawed; stigma obscurely 5-lobed: fruit a top-shaped caps. B.M. 2890.
Hook. &Arn. Shrub: leaves thickish, broadly ovate, acutish or obtuse, bluntly serrate, essentially glabrous: flowers red, long-tubular, in a stocky, often branching, terminal raceme; calyx-lobes with marginal glands; stigma peltate, obscurely 5-lobed: fruit a gla-brescent caps. F.S. 6:632. - Excellent. variety sangufnea is a horticultural variety with flowers more crimson.
Gardn. Half-hardy S., 2-5 ft., glabrous throughout: leaves thick, oblong, acutish, serrulate, with tiny resinous dots: flowers pink, in close, terminal clusters. B.M. 4274. - Excellent. Organ Mts., Brazil.

Cham. &. Schlecht. (E. Candida, Lem.). Shrub, to 3 ft.: leaves oblong-ovate or obovate, obtuse, apiculate, or more rarely acute, with a few blunt teeth on upper part, or wholly entire: flowers white, in a terminal, many-flowered panicle. J.F. 403.
DC. (E. floribunda, Reichb. E. floribunda, HBK. variety montevidensis, Cham. & Schlecht.). Shrub, to 9 ft.: leaves thick, elliptic, obtuse, finely serrate, glabrous, shiny above: flowers white, in a terminal, many-flowered panicle; petals clawed; stigma obscurely 4-5-lobed: fruit a top-shaped caps., crowned by the obviously longer style. G. 25:576; 27:465.
HBK. Shrub: leaves oblong-ovate, obtuse, very minutely crenulate-serrate or entire, glabrous or nearly so: flowers white, in many-flowered, compound, axillary or terminal panicles; petals clawed; stigma peltate, 2-lobed: fruit a caps., crowned by the equal or barely longer style. G.C. III. 47:53.
cc. Width of leaves not over. 1/2in.
Remy. Densely lvd. shrub: leaves obovate, obtuse or nearly so, finely serrate, at least on upper part, glabrous, small: flowers white, in very dense racemes; petals spatulate, clawed: fruit an obovate caps.
Pers. (E. Philippiana, Mast. E. virgata variety Philippiana, Engler. E. stricta, Gay). Densely lvd. shrub, half-hardy south of Washington: leaves stiff, lanceolate or obovate, obtuse to acute, tapering at base, with minute rather distant teeth on upper part, glabrous or nearly so, small: flowers white, axillary, scattered, or sometimes massed near the tips of the branchlets; petals spreading, scarcely if at all clawed: fruit a globose caps. G. 27, p. 464. Gn. 66, p. 64.
Vilm. & Bois. Fig. 1422. A graceful shrub (artificial hybrid of E. macrantha and E. virgata): leaves linear-ovate, obtuse or acutish, minutely serrulate, small, in short racemes at the ends of the branchlets.
Fig. 1422. Escallonia langleyensis.
E. alba, a name found in some of the catalogues, is not determinable. - E. pendula, Pers. Shrub with red flowers, in narrow racemes to more than 1 ft. long, and leaves resembling those of tobacco. Desirable. - E. rosea. An unidentified catalogue name which in at least one instance, certainly does not refer to E. rosea, Griseb., a very little known species,
