A genus of Heath - like plants with narrow leaves and cup-shaped flowers. They are natives of Australia, and prefer cool greenhouse treatment. A peaty soil with a little sand suits them best, and watering must be carefully attended to in winter. They are propagated from cuttings, 2-3 in. long about August, in very sandy soil, and are kept moist, shaded, and covered with bell-glasses until rooted. The best kinds are: elatior, with rose-red flowers in dense clusters; heterophylla (fig. 267), bright red; megastigma, brown and yellow; polygaloefolia, rosy lilac; and serrulata, deep rose. They are sweet-scented, and flower during the winter season.
