so large and they are produced in June. P. Lemomei is 

 a beautiful hybrid, elegant in growth, and attaining a 

 height of four or five feet. It blooms in June and the 

 flowers are white and about an inch in diameter. Bottle 

 d* Argent is an extremely elegant form, bearing double 

 white flowers ; and Gerbe de Neige, another variety of 

 P. Lemoinei, is extremely beautiful, being of moderate 

 stature with slender growth, and free in blooming, the 

 flowers of medium size and pure white ; P. mexicanus 

 is a desirable species, with an average height of six feet, 

 the flowers two inches in diameter, pure white with 

 conspicuous yellow stamens. 



PRUNUS. The Plums remarkable for the beauty of 

 their flowers, and especially desirable are all shrubs of 

 moderate growth. They will thrive in any ordinary 

 soil, and can be the most readily propagated by 

 budding, as in the case of the plums grown for their 

 fruits. 



Two only will be recommended and they are so

 garden. The first is the Double Sloe or Blackthorn 

 (Prunus spinosafl. pL). The growth is light and elegant, 

 and the flowers are white, perfectly double, resembling 

 small rosettes, and the second, P. triloba, a Chinese 

 species of compact, erect growth, and remarkably free in 

 blooming. The flowers are double, about an inch in 

 diameter, and bright pink, and produced nearly the 

 whole length of the shoots of the previous season. It 

 should have a warm and conspicuous position in the 

 shrubbery border, and it is very effective when grown 

 against a wall and somewhat loosely trained. 



RUBUS, OR BRAMBLES. The Brambles form a rather 

 large group, and in extensive pleasure-grounds where 

 wild gardening receives attention, half a dozen or so 

 may be planted ; but for the majority of gardens Rubus
