double flowering, is a very neat shrub, and flowers abun- 

 dantly. M. commiinis, leucocdrpa, white-fruited myrtle. 

 M. itdlica variegdta, striped leaved ; M. itdlica maculdta, 

 blotch leaved, are very fine shrubs ; and M. tomentosa, 

 Chinese myrtle, is a magnificent erect growing shrub, with 

 a white down over the foliage ; the flowers are the largest 

 of the genus. When they first expand they are purple, 

 and afterward change to white, so that there are beautiful 

 flowers of several shades of colour on the plant. We have 

 not the smallest doubt but this species will become, in 

 many instances, as plentiful as the common myrtle. It is 

 more easily grown, but cannot s:and much exposure to the 

 sun in summer. M. tenuifolia is a very fine plant, and a 

 native of New South Wales. Myrtles in general should 

 be sprinkled with water in the evening, to keep off the red 

 spider. (Soil No. 11.) 



Nandlna domestica, the only species, and a popular 

 shrub in the gardens of Japan, where it is called Nandin. 

 It has supra-decompound leaves, with entire lanceolate 

 leaflets, a kind of foliage that is very rare ; the flowers are 

 small whitish green, in panicles, succeeded by berries of 

 the size of a pea; drain the pots well. (Soil No. 1.) 



Nerium (Oleander) is a genus of beautiful erect grow- 

 ing evergreen shrubs, of the easiest culture, and abundant 

 in flower. N. oleander is the common rose-coloured single 

 flowering species, from which many varieties have origi- 

 nated. At present the most popular is N. oleander splen- 

 dens, which has a double rose-coloured flower, N. o. stridta, 

 fl. JD/., has double striped flowers. N. meter ophy Hum has 

 very large double pink flowers. N. o. raginot, or tangle, 

 has deep crimson flowers striped with white, though they 

 are frequently of a pink colour. N. o. purpiirea, dark red. 

 There is one that has got into our collections as double 

 white, which is only semi-double. N. oleander elegan- 

 tissimum, a most beautiful plant, with deep silver-edged 

 foliage ; and the young wood is striped white and green. 

 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. (Soil No. 12.) 



Oleas, Olive, about twelve species and varieties. O. 

 Europsea longifolia is the species that is cultivated to such
