L. galegiformis and L. Helveticus are names in the American 

 trade, but cannot be placed botanically. L. tuberbsus, Linn., has 

 been imported by an American amateur. It differs from all de- 

 scribed above by having tubers. It is a native of the northern 

 parts of the Old World, and bears red flowers, which are gener- 

 ally fewer and smaller than those of L. sylvestris.

 the Kalmias are known as Laurels. The Cherry Laurel

LAURUS ndbilis (Laurus is the ancient name) is 

 the Sweet Bay tree of the florists, the most universal of 

 all evergreen tub-plants. It is native to the Mediterra- 

 nean region, sometimes attaining a height of 40 to 60 ft., 

 but rarely assuming a true tree-like form. As a culti- 

 vated subject, it is grown as a small standard tree, with 

 a close-sheared top. The plant endures abuse and 

 neglect, the head can be trimmed to almost any shape, 

 and the growth ma5 r be kept within small limits year 

 after year. F.R. 1:669 (Fig. 1244). It is, therefore," the . 

 most popular of plants for decoration of open-air or ex- 

 posed restaurants, esplanades, architectural appurte- 

 nances, and the like. Although much used in An;erica, 

 it is still more popular in Europe. Of the European 

 dealers one may order plants with heads trained to pyra- 

 mids, cones, globes, and the like, and with bodies long 

 or short. The plant will endure considerable frost. It 

 is grown in the open in England: "The Sweet Bay 

 bush in the farmer's or cottage garden comes with its 

 story from the streams of Greece, where it seeks mois- 

 ture in a thirsty land along with the wild Olive and the 

 Arbutus. And this Sweet Bay is the Laurel of the poets, 

 of the first and greatest of all poet and artist nations of 

 the earth the Laurel sacred to Apollo, and used in 

 many ways in his worship, as we may see on coins, and 

 in many-other things that remain to us of the great peo- 

 ples of the past" (Gn. 47, pp. 301, 307). Although so 

 universally used, there are few important horticultural 

 varieties, the variegated-leaved and crisped-leaved 

 forms being the best known. Prop, by cuttings, and 

 sometimes by seeds. 



Laurus gives name to the family Lauracece, which in- 

 cludes Cinnamomum, Camphora, Persea, Sassafras, 

 Benzoin, and other genera. Many species have been re-
