238 green-house — repotting. [March. 
dtta are thought the most superb. They have bright crimson 
flowers, and are yet rare in our collections. The pots should 
be well drained; flowers are either in racemose spikes or 
solitary, which is rather too much distinction for the same 
genus. (Soil No. 6.) 
Lasiopctalums, only two species. There were a few more, 
but they are now Thomashts, plants of no merit whatever 
in regard to flower ;. foliage three-lobed, small, rough, and 
rusty-like. Thomdsia solandcca and T. querci folia are the 
best species ; foliage of the former is large, cordate, and 
deeply indented ; they are all of the easiest culture. (Soil 
No. 1.) 
Laiirus. A few species are green-house plants. This 
genus has been divided to Cinnambmum; still there are a 
few celebrated plants in the original. L. nbbilis, sweet bay, 
though hardy, is kept under protection. It will bear the 
winter with a little straw covering; notwithstanding, there 
should be a plant kept in the house in case of accident by 
frost or otherwise ; there is a variegated variety of it. L. 
indica,, royal bay, L. fastens, L. aggregdta and L. glauca, 
are favourites. There is a species known in our collections 
as L. sedbra. The Camphor tree, known as L. camphbra, 
is Ginnamomum camphora ; the wood, leaves, and roots of 
this tree have a very strong odour of camphor. It is ob- 
tained by distillation from the roots and small branches, which 
are cut into chips, and put into a net suspended within an 
iron pot, the bottom of which is covered with water, having 
an earthen head fitted in it; heat is then applied, and the 
steam of the boiling water acting upon the contents of the 
net, elevates the camphor into the capital, where it concretes ' 
on the staws, with which this part of the apparatus is lined. 
They are all fine evergreens (which the name denotes), and 
easily cultivated. (Soil No. 10.) 
Lavdndulas, Lavender. About seven species belong to 
the green-house, and a few of them very pretty soft-wooded, 
half shrubby plants, and, if touched, are highly scented. L. 
dentdta has narrow serrated foliage, very neat; L. formosa, 
and L. phuiata are desirable; blue flowers on a long spike; 
should be kept near to the glass ; they are of the easiest cul- 
ture. (Soil No. 7.) 
Lcclicnaidtia ; four species of pretty dwarf blooming plants. 
L. formosa is almost always a picture with its bright scarlet 
flowers and heath-like foliage, and ought to be in every col-
