Shrub or tree
Trees, shrubs, or subshrubs, often evergreen, sometimes epiphytic. Leaves alternate, sometimes becoming aggregate into pseudo-whorls, simple, pinnately veined, exstipulate. Flowers in racemes, corymbs, panicles, clusters or solitary, actinomorphic or zygomorphic, bisexual. Calyx of 5(-8)sepals, free and borne on ovary, or united into tube at base. Corolla of 5(-10)petals united at base or almost to apex, tubular, barrel-shaped, urn-shaped, campanulate, funnel-shaped or salver-shaped. Ovary inferior or superior, 4-5(-20)-celled; style cylindric; stigmasimple; ovules numerous, axile. Fruit a berry or 5(-20)-valved capsule, sometimes enclosed by enlarged fleshy calyx.. . Members of the Ericaceae are of great horticultural importance in North temperate countries, particularly in Europe and north America where many genera are prized as ornamentals, including Rhododendron (by far the most important), Enkianthus, Pieris, Gaultheria, Vaccinium and Agapetes. Bhutan is particularly rich in Ericaceae, and there exists some economic potential for commercial production ot the rare species.. . The family is treated here in a broad sense, including those genera sometimes placed separately in Vacciniaceae.
Evergreen shrubs or trees, often aromatic;indumentum of simple or compound hairs or peltate scales. Leaves alternate or clustered at branch ends, coriaceous,entire. Flowers interminal condensed racemoes, rarely solitary, weakly zygomorphic. Calyx 5(-8)-lobed, often reduced to shallow cup. Corolla campanulate, funnel-shaped or salver-shaped, rarely cylindric, with5-10 long or short lobes. stemans (5-)10(-18). Ovary 5-20-celled;stigma capitate. Capsule 4-20-valved.
Shrub 1-2m or tree upto 15m; young shoots puberulous to tomemtose. Leaves elliptic-oblanceolate, 7-17*2-5cm, acute or very shortly acuminate, base cuneate, lower surface densely matted white, silvery or fawn tomemtose, (sometimes obscured by loose red-brown tomemtum) or loosely whitish or fawn floccose; petioles 8-15mm. Racemes compact, 10-20 flowered; pedicels 5-10mm, hairy and glandular. Calyx 1-2mm, shortly 5-lobed, glandular or glabrous. Corolla tubular-campanulate, 3-4.5cm, 5-lobed, bright red, pink or more rarely white, with darker spots and nectar pouches. Stamens 10. Ovary white tomemtose; style glabrous. Capsules slightly curved, 1.5-2.5 * 0.7-0.9cm. . Leaves as described for R.arboreum but closely matted white or silvery tomentose beneath; flowers red.
