same as L. riibra, only the foliage glaucous. They are 

 all valuable plants, and are obtained by seed from the East 

 Indies. They require plenty of pot room. (Soil No. 12.) 



Laurus. This genus, though of no beauty in flower, is 

 generally admired in collections for its fine evergreen foli- 

 age, and aromatic or spicy flavour, and several trees are 

 important in medicine. The most esteemed are given to 

 a genus named Cinnamomum, as has been observed in the 

 green-house, (see March.) L. Chloroxylcn is the Cogwood 

 of Jamaica. L. persea is now Persea gratissima, Alliga- 

 tor-pear, a fruit about the size of a large pear, and greatly 

 esteemed in the West Indies ; the plant is generally known 

 in our collections. C. verum is the true Cinnamon of 

 commerce. 



The part taken is the inside of Uie bark when the tree is 

 from five to eighteen years old. The leaves are three- 

 nerved, ovate, oblong ; nerves vanishing toward the point, 

 bright green above, pale beneath, with whitish veins. 

 This plant ought to be kept in the warmest part of the 

 hot-house. C. cassia is frequently given under the former 

 name, but, when compared, may be easily detected by the 

 leaves being more lanceolate and a little pubescent. They 

 both make handsome plants, but require great heat. 

 Drain the pots well of the delicate sorts. (Soil No. 13.) 



Magnifera, Mango tree. There are two species. M. 

 indica is in our collections, and bears a fruit which is so 

 highly esteemed in the East Indies, as to be considered 

 preferable to any other except very fine pine apples. The 

 leaves are lanceolate, and from six to eight inches long, and 

 two or more broad. The flowers are produced in loose 

 bunches at the end of the branches, but of no beauty, and 

 have to be artificially impregnated, or it will scarcely pro- 

 duce fruit. The shell is kidney-shaped, and of a leathery 

 crustaceous substance. They contain one seed, and in 

 their indigenous state are more juicy than an apple. 

 Drain the pots well, as the roots are apt to get sodden from 

 moisture. The other species goes under the name of op- 

 positifolia, but we question if if is not only a variety, for 

 it has every character of the one just described. (Soil No. 

 11.)
