LYONIA (named in honour of John Lyon, a col- 
lector of North American plants). Orp. Ericacee. This 
genus, formerly included under Andromeda, comprises 
about eight species of hardy or greenhouse trees or 
shrubs. They are natives of North America, Mexico, 
Jamaica, and Cuba. Flowers small, in fascicles or 
racemes, sometimes paniculate, axillary; corolla urceo- 
late or globose, pubescent, four or five-dentate ; teeth 
recurved. Leaves alternate, petiolate, persistent or 
deciduous, entire or obscurely serrulate. Lyonias succeed 
best in peat or sandy loam. Propagation is effected 
by layers; or by seeds, which, being extremely small, 
require careful sowing in a sandy-peat soil. 
L. ferruginea (rusty-coloured). f. white ; pedicels aggregate, 
axillary. April and May. J. coriaceous, stiff, crowded, on short 
petioles, cuneate-lanceolate, acute, quite entire, convex, with 
revolute edges. h. 20ft. Carolina to Florida, 1774. Whole 
lant clothed with brown, umbilicate, furfuraceous scales. Low 
greenhouse shrub. SYN. Andromeda rigida (under which name 
it is figured in L. B. C. 430). 
(Jamaica). fl. white; corolla oblong. July. 
** Juntish, evergreen, glabrous, lanceolate or elliptical-lanceolate, 
Š i r nd, reticulated with veins, and at length 
Gunctate beneath. Jamaica. Greenhouse shrub’ (B. M. 421)
