palms. L. harbbnica is one of the finest of the Palmse, not 
growing to great magnitude ; the leaves or fronds are plaited 
flabelliforrn, leaflets smooth at the edge, footstalk spiny, and 
the plant spreading. L. rubra, fronds same as the former, 
but leaflets more divided and serrulate ; footstalk unarmed : 
foliage reddish. L. glaucophylla same as L. rubra, only the 
foliage glaucous. They are all valuable plants, and are ob- 
tained 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 Marcli). L. Chloroxylon 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 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.) 
Mangxfera, Mango tree. There are two species. M. 
indlca 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 sis 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
