ARBORETUM ET FRUTICETUM BRITANNICUM. 



summer's shoots with the leaves on, will root in a vessel of water 

 in a very few weeks ; and, if an inch of soil be placed at the bottom 

 of the vessel, the fibres will root into it, and the plants may be 

 used as if they had been struck in the usual manner. Layers, 

 put down in moist soil, root the first year.

 2007, Leaves distichous, linear, acute, evergreen, coriaceous, 

 glabrous, opaque. {Lamb.) An evergreen tree. Discovered by 

 Mr. Menzies, on the north-west coast of America, in 1 796 ; and 

 immense trees of it were seen by Dr. Coulter in 1836 ; but it has 

 not yet been introduced. It will probably prove hardy ; and, in 

 that case, its introduction would be exceedingly desirable.

Derivatioji. From Juruprus, rougli or rude, CeU., the plants of this genus being stiff shrubs ; or 

 from junioi'es pariens, from the young and old leaves being on the tree at the same time, or with 

 reference to the young fruit being produced before the old fruit drops off. 



Gen. Char. Male flowers in axillary or terminal catkins. Pollen of each 

 flower in 3 6 cases, attached to the basal edge of the scale, and prominent 

 from it. Female flowers in axillary catkins, resembling a bud ; consisting 

 of 13 fleshy ovaries ; bracteated at the base. Ovules 1 to an ovary. The 

 ovaries coalesce, and become a fleshy juicj' strobile, resembling a berry. 

 Seeds 1 3, each obscurely 3-cornered, and having 5 gland-bearing pits 

 towards the base. ((?. Don.) 



Leaves simple, opposite or ternate, exstipulate, evergreen ; narrow, 

 rigid, and not rarely minute and scale-shaj)ed. Flowers yellowish, from the 

 colour of the pollen. Trees evergreen, low, or shrubs ; natives of Em-ope, 

 Asia, Africa, and North America ; mostly hardy in British gardens. 



The wood of all the species is more or less aromatic, and very durable. The 

 species, with the exception of three or four, which have grown to some size, 

 and ripened fruit in England, are very imperfectly known to British cultivators ; 

 and, probably, some of those kinds which we have given as distinct species 

 may prove not to be so. We could not, however^ avoid this, from the im- 

 possibility of seeing any plants of many of the kinds, but those which were 

 quite young. All the species are readily propagated by seeds, which retain 

 their vitality, when kept in the berry, for several years ; and, when sown, 

 lie one year, and often two years, before they come up. They may also be 

 increased by cuttings, planted in sandy soil, in a shady situation, in the autumn, 

 and covered with a hand-glass during winter ; or by layers. The species in 

 British gardens are thus arranged :
