ceolate. {Dec. Prod., iii. p. 206.) A native of moist shaded places 

 in Virginia and Carolina. Judging from the plant in the Horticul- 

 tural Society's Garden, it only differs from the species in being a 

 little more vigorous.

Deutzia scdbrci Thunb. {Don's Mill., 2. p. 808. ; Bol. 

 Peg., t. 1718. ; and our^g. 681.) is a climbing or an as- 

 cending shrub, with ovate, acuminated, serrated leaves ; 

 scabrous stellate hairs ; and with white flowers, in com- 

 pound panicles. It is a native of Japan, where the 

 leaves are used by joiners in smoothing and polishing. 

 It was introduced in 1822; grows to the height of 6 ft. 

 or 7 ft., flowering in May or June ; and appears to be 

 as hardy as Caprifolium japonicum. It is a very showy 

 free-flowering plant, and deserves a place in every col- 

 lection. It is readily propagated by cuttings or layers, 

 and thrives in any light soil, trained to a wall, and 

 slightly protected during severe frosts. Plants, in the 

 London nurseries, are 5s. each. 



D. corymbosa R. Br., Don's Mill., 2. p. 808., Royle 

 Illust., t. 46. f. 2. ; Philadelphus corymbosus Wall. ; has 

 glabrous leaves, and white flowers. It is a native of 

 Kamaon ; grows to the height of 3 ft. or 4 ft., and pro- 

 bably is as hardy as the preceding sort. (See p. 173.) 

 in the London Horticultural Society's Garden. 



D. staminea R. Br., Philadelphia stamineus Wall., has entire, scabrous, lanceolate leaves, and 

 white sweet-scented flowers. It is a native of Nepal, on high mountains; but it is not yet intro- 

 duced. 



D. Brunbnia Wall., Leptospermum scabrum Wall., has ovate leaves, and axillary white flowers. 

 It is a native of Kamaon, but has not yet been introduced. The last three sorts are probably only 

 varieties of one form.

OF THE HALF-HARDY LIGNEOUS PLANTS OF THE ORDER i»/YRTA v CE#:. 



This is one of the most natural groups of woody plants ; and, in general, 

 may be easily recognised by its opposite entire leaves, full of transparent dots ; 

 which indicate the presence of an oil which is fragrant, aromatic, pungent, vola- 

 tile: hence the grateful perfume of the leaves, flowers, and fruit of the greater 

 number of plants belonging to this order. Like most highly aromatic woody 

 plants, the species are chiefly inhabitants of warm climates. The common 

 myrtle is a native of Europe; but all the other genera belong to North or 

 South America, Africa, Asia, or Australia. A great many of the species are 

 very suitable for a conservative wall, from their being evergreen, and from the 

 beauty of their foliage and flowers; and many of them, in the neighbourhood 

 of London, require little more protection than the common myrtle. All the 

 species may be readily propagated by cuttings. The half-hardy, or green- 

 house, species, cultivated in British gardens, will be found arranged in the four 

 following groups:— I. Melaleucese; II. EuleptospeYnieag ; III. Myrteae; and 

 IV. Chamaelaucieae.
