palms. L. harhonica is one of the finest of the Pahnas, 

 not growing to great magnitude ; the leaves or fronds are 

 plaited flabelliform, leaflets smooth at the edge, footstalk 

 spiny, and the plant spreading. L. riibi'a, fronds same as 

 the former, but leaflets more divided and serrulate ; foot- 

 stalk unarmed: foliage reddish. L. glaucophi/lla same as 

 L. riihra, 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 flavor, and several trees are 

 important in medicine. The most esteemed are given to 

 a genus named Cinnrnnomiim, as has been observed in the 

 green-house (see March). L. Chhrdxi/lon is the Cogwood 

 of Jamaica. L. persea is now Fersea 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. vdrum is the true Cinnamon of com- 

 merce. 



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

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

 nerved, ovate, oblong ; nerves vanishing towards 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.) 



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

 iiidica 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
