GREEN-HOUSE — REPOTTING. [^MarcJl. 



flowers^ and are yet rare in our collections. The pots should 

 be well dniined; flowers are either in racemose spikes or 

 solitary^ which is rather too much distinction for the same 

 genus. (Soil No. 6.) 



LasicypetalumSj only two species. There were a few more, 

 but they are now Thomdslas, plants of no merit whatever 

 in regard to flower; foliage three-lobed^ small, rough, and 

 rusty-like. Thomdsai solandcea and T. quercifdlia are the 

 best species; foliage of the former is large, cordate, and 

 deeply indented ; they are all of the easiest culture. (Soil 

 No. 1.) 



Laurus. 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. noMlis, 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. foetenSyL. aggregdta^ and L. glauca, 

 are favorites. There is a species known in our collections 

 as L. scabra. The Camphor tree, known as L. camplLbra, 

 is Cinnamomum campliora ; the wood, leaves, and roots of 

 this tree have a very strong odor 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 straws, 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. formbsa 

 and L. pinnata are desirable ; blue flowers on a long spike ; 

 should be kept near to the glass; they are of the easiest 

 culture. (Soil No. 7.) 



LecJienaidtia ; four species of pretty dwarf blooming plants. 

 L. formbm is almost always a picture with its bright scarlet 

 flowers and heath-like foliage, and ought to be in every col-
