13. sicaefolia, Salisb. (E. pygmaea, Andr. and Hort.). Dwarf cushiony heath, perhaps best treated in the alpine garden, 4-8 in. high: branches ascending, nearly glabrous leaves in whorls of 3, linear-acuminate, 2 1/2-5 lines long: flowers in 3's, the corolla dark purple, its segments ciliolate. L.B.C. 5:468. B.M. 2263.

15. flacca, E. Mey. (E. ciliaris, Thunb., not of Hort.). An erect shrub, usually branched, but not diffuse, the branches pubescent or glandular hairy: leaves in 3's, rarely in 4's on the same plant, spreading, usually "linear, as if sub-terete," the margins revolute, 1 1/2-2 1/2 lines long: flowers in 3's, the corolla bell-shaped to tubular, the segments about a third as long as the tube; ovary sometimes hairy on the top.

1175. Gng. 9:35 (the last two as E. cupressina). 17. gracilis, Salisb. Leaves in 4's, somewhat erect;bracta remote: sepals smaller, lanceolated; anthers with a short, sharp point. L.B.C. 3:244 (pale violet). G. 25:602. Gn.
76, p. 11. "Flowers purplish red." variety autumnalis, Hort.
Flowers Sept. variety vernalis, Hort. Flowers in Oct. and Nov. 18. persoluta, Linn. Fig. 1414. Essentially a white-flowered and very variable species, particularly as regards hairiness: leaves erect or spreading, hirsute or glabrous: corolla small, originally 1 1/2 lines long; lobes ovate, 2-3 times shorter than the tube, the sinuses acute, narrow. S. Africa The numerous varieties Bentham found impossible to separate either in the wild or in cultivation variety hispidula, Benth. Slightly hirsute: leaves 2 1/2-3 lines long, rough: anthers sub-ovate. variety laevis, Benth. Leaves shorter, blunter, often appressed, glabrous: anthers subglobose. variety subcarnea, Benth., has the corolla-lobes more evident. To this last variety Bentham seems to refer most of the horticultural varieties cult, under the name of E. persoluta. E. assurgens, Link, he refers to the first variety; E. caffra of Linnaeus to the first, but of L.B.C. 2:196 (and the trade?) to the second. E. regerminans of Linnaeus is a distinct species (figured in L.B.C. 17:1614 as E. Smithiana); of the trade=E. persoluta variety hispidula: of L.B.C. 18:1728=2?. persoluta variety subcarnea.
Flowers in Feb and March, while other related species mostly flower in March and April.

19. formosa, Thunb. (E. grandinosa, Hort.)- Erect shrub, 1-2 ft., the branches hairy, covered with leaves in whorls of 3: leaves glossy, channeled, the younger ciliate, about 1 1/2 lines long: flowers in 3's, the corolla white, with
8 longitudinal channels, sticky. Andr. Heathery 265.
20. melanthera, Linn. Fig. 1415. Leaves thick, obtuse, grooved on the back, younger ones often rough, with glands; bracts mostly crowded: flowers rosy; sepals obovate, keeled, colored; anthers black; ovary villous.

21. fragrans, Andr., not Salisb. Leaves opposite, erect-appressed, acute, always glabrous; bracts loose, sepal-like: flowers in 2's; sepals ovate, keeled, green; ovary glarous or slightly bristly at the tip. B.M. 2181. L.B.C. 3:288.
The following are mostly kinds that have been grown successfully in small quantities in this country but appear not to be advertised in American trade catalogues. H=nard-wooded; the rest are soft-wooded. S. Africa, unless stated. Aside from these, E. scoparia, Linn., of S. Eu., is sometimes listed: 2-3 ft., glabrous: leaves in 3's: flowers greenish, in 1-sided racemes; calyx-lobes about half the length of the subglobose corolla. E. capensis also appears, but it is apparently only a catalogue name.
E. ampullacea. Curt. Leaves ciliate, mucronate: bracts colored; flowers mostly in 4's; corolla ventricose, very sticky, typically white, lined with red; limb spreading, white. variety rubra is the only form cultivated B.M. 303. L.B.C. 6:508. H. - E. arborea variety alpina, W. I. Beau. An alpine variety, grown only at Kew. It is a stiff erect bush with tiny white flowers in plume-like clusters. Gn. 75, p. 384. - -E. aristata, Andr. Readily distinguished by the long bristle which ends the leaves: leaves recurved: flowers in 4's; sepals keeled with red; corolla sticky, 1 in. long, ventricose, but with not so long and narrow a neck as in E. ampullacea. B.M. 1249. L.B.C. 1:73. H. - E. barbata, Andr. Bristly and glandular - pubescent: leaves in 4's: corolla urn-shaped, villous; ovary villous. L.B.C. 2:124. - E. Bowieana, Lodd. Leaves in 4's to 6's: infloresence axillary; corolla tubular, slightly inflated; limb erect or scarcely open. L.B.C. 9:842. - E. Burnettii, Hort. Hybrid. F.S. 8:845. - E. Cavendishiana, Hort. (E. Cavendishii, Hort.). Hybrid of E. depressa x E. Patersonii. Leaves in 4's, margins revolute: flowers in 2's to 4's; corolla tubular; stamens included; anthers awned.

G. 6:489; 10:243. - E. conspicua, Soland., is a species with club-shaped, villous flowers and villous leaves in 4's. variety splendens, Klotzsch, with the leaves and sepals shining green and pubescent corollas, includes E. elata, Andr. L.B.C. 18:1788. - E. cylindrica, Andr. and Hort. Important hybrid of unknown parent-" age, cult, since 1800. Leaves in 4's: flowers nearly sessile; corolla 1 in. long, brilliant rosy red, with a faint circle of dull blue about two-thirds of the way from the base; anthers awned, included; ovary glabrous. L.B.C. 18:1734. R.H. 1859, p. 42. - Flowers very showy and unusually long. The oldest E. cylindrica. That of Wendland is a yellow-flowered species unknown to cultivated - E. Devoniana, Hort. Hybrid. Flowers rich purple. H. - E. elata, Andr.= E. conspicua variety splendens. - E. Irbyana, Andr. Allied to E. ampullacea, but with corolla narrower at the base and tapering with perfect regularity to just below the limb, where it has a prominent red bulge. It is also distinctly lined with red, and the sepals are green, although the bracts are colored, as in E. ampullacea. L.B.C. 9:816. H. - E. nigrescens is presumably E. melanthera (H. D. Darlington). - E. pallida.
A confused name. The oldest plant of this name is Salisbury's, which has an urn-shaped corolla, flowers often in 3's, pubescent and hirsute branches and leaves in 3's. L.B.C. 1:72 (as E. pura). E. pallida of the trade is probably the tubular-flowered hybrid of Loddiges in L.B.C. 14:1355, which has axillary and terminal flowers, and leaves in 4's to 6's. - E. perspicua., Wendl., has a tubular or slightly club-shaped corolla, leaves in 4's, pubescent or rough-hairy, and flowers in l's to 3's, but the plant in the trade is probably E. perspicuoides, Forbes, a hybrid, with longer and woollier hairs, flowers somewhat in umbels, nearly 1 in. long. Only variety ericta is grown here. - E. Syndriana is grown by Louis Dupuy. - E. translucens, Andr. Perhaps the first of all the garden hybrids between E. tubiflora and E ventricosa. Leaves rigid, with or without long, soft, red hairs: flowers in umbel-like heads; bracts remote; corolla rosy, 8-9 lines long; tube narrowly ventricose, pubescent limb short, spreading; ovary sessile. Andr. Heaths, 295. Bentham considers this a synonym of E. spuria, Andr. Heaths. 60. Schultheis says "it is the finest erica grown; a poor propagator but good grower.
Takes 3 months to root." - E. tricolor is perhaps the most confused name in the genus, and apparently one of the important kinds abroad, where it has many varieties and synonyms. In the trade it seems to stand for a handsome heath, with leaves in 4's, distinctly ciliate and terminated by a bristle: flowers in umbels of 8-10, 1 in. long, a little too inflated at the base for the typical tubular form, rosy at the base, then white, then green, and then suddenly constricted into a short neck; pedicels red and exceptionally long. This description is from L.B.C. 12:1105 (as E. eximia), one of the earliest pictures of these charming hybrids which Bentham refers to the hybrid E. aristella, Forbes. - E. Wilmorei, Knowles & Westc. (E. Wilmoreana and Vilmoreana, Hort.). Hybrid: corolla tubular, bulged below the lobes, slightly velvety-hairy: flowers in l's to 3's, rosy, tipped white. R.H. 1892, p. 202. A.F. 4:251. G.C. III. 19:201. A.G. 21:869. variety glauca, Carr., has nearly glaucous foliage. variety calyculata, Carr., has a large additional calyx.
