THE NURSERY-BOOK. 



Laurel, Mountain. See Kalmia. 

 Laurus (Laurel). Laurinecc. 



Increased by seeds, layers, and by cuttings, placed under 

 a hand-glass in sandy soil. Also propagated by root-cuttings. 



Laurustinus. See Viburnum. 

 Lavandula (Lavender). Labiate?. 



Divisions. When the flowers are fully expanded, cuttings 



may be made. These should be inserted in sandy soil, under 



a frame.

 under a glass, in heat. 



Laxmannia. Liliaceoe. 



Seeds. Propagation is usually effected by divisions or 

 bulbels.

 in a cold-frame. 



Leianthus. Gentianecc. 



Seeds, under cover ; or cuttings of young shoots may be 

 made, and inserted in sandy soil under glass. 



Leiophyllum (Sand Myrtle). Ericaceae. 



May be freely increased by seeds, sown in pans and placed 

 in a frame. By layers in autumn. 



Lemon (Citrus Limonum). Rutacea. 



The named sorts are budded upon either orange or lemon 

 stocks. Orange stocks are probably most generally pre- 

 ferred, as they are adapted to a great variety of soils, and 

 vigorous trees nearly always result. The budding is per- 

 formed in the same manner as upon the orange, which see. 

 Lemons are often grown from cuttings of the mature wood,
