growing evergreen sbrubs, of the easiest culture, and 

 abundant in flower. N. oleander is the common rose 

 coloured single flowering species, from which six varie- 

 ties have originated. At present the most popular is 

 N. oleander splendens, which has a double rose coloured 

 flower. There is one that has got in our collections 

 as double white which is only semi-double. We have 

 seen a white, variety as double as JV. o. splendens, and 

 have no doubt but in a few years it will be plentiful. 

 N. oleander eleganlissimum, a most beautiful plant, with 

 deep silver-edged foliage; and the young wood is strip- 

 ed white and green. We are not positive in respect to 

 the beauty of its flowers, but it has a high character. 

 We have heard of a double yellow variety, but the re- 

 ports are not properly authenticated ; and we doubt it 

 very much. There are likewise single yellow, single 

 white, and single blotched varieties of N. oleander. They 

 are subject to the small white scaly insect, and should 

 be frequently washed, as has been directed, to keep it 

 off. 



Oleas, Olive, about twelve species and varieties. 

 O. Europcea longifolia, is the species that is cultivated 

 to such an extent in the south of France, and Italy. O. 

 Europcea latifoliais chiefly cultivated in Spain. The 

 fruit is larger than that of Italy, but the oil is not so 

 pleasant, which is obtained by crushing the fruit to a 

 paste, and pressing it through a woollen bag, adding 

 hot water as long as any oil is yielded. The oil is then 

 skimmed off the water, and put into barrels, bottles, 

 &c. for use. The tree seldom exceeds thirty feet, and 

 is a branchy glaucous evergreen, and said to be of great
