“ In these physiognomic considerations we by no means comprise under the name of Heaths the whole of the natural family of Ericaceæ, which on account of the similarity and analogy of the floral parts includes Rhododendron, Befaria, Gaultheria, Escallonia, &c. We confine ourselves to the highly accordant and characteristic form of the species of Erica, including Calluna (Erica) Vulgaris, L., the common heather. ”

“ All are easily propagated by cuttings or by layering. The cuttings can be taken at almost any time of the year, and root quickly, the young plants attaining a good size by the end of the second year.
Ericaceæ.—This order includes all the so-called American plants, such as Pernettya, Gaultheria, Leucothoë, Andromeda, Pieris, Zenobia, Erica (Heath) , Calluna (Common Heather, Ling) , Kalmia, Ledum, Clethra, and Rhododendron (including Azalea) . These can all be increased by seeds, layering, and, in addition, the first two by division of the old plants.
