PBOPAGATIOK OF PLANTS. 



from Conneoticut southward, the most common heing known as the 

 Groundsel tree (-B. halimifdka). Propagated by seed and ripe wood 

 cuttings. 



Banksia. — ^A genus of evergreen shrubs, native of Australia, and 

 cultivated for the beauty of their foliage. There are a. large number 

 of species cultivated in European gardens, where they are employed for 

 table decorations and for ornamenting rooms on festive occasions. Prop- 

 agated by well-ripened cuttings, separated carefully below a joint, and 

 then planted in sand without removing any but the lower leaves. Only 

 moderate heat is required, and 

 the ail- in the frames should not 

 be too confined or moist. 



Senthamia. — A genus of 

 shrubs, of the order Gornaceoe, 

 and by botanists it is now re- 

 feiTed to as the genus Oornus 

 (Dogwood). Of the two species 

 in cultivation, the £. Japonica 

 is the most hai-dy, but the lead- 

 ing shoots suffer, more or less, 

 every winter in my gi-ounds. 

 Propagated by seeds and layers, 

 or by grafting on the Dogwood. 



Berberidopsis. — An ever- 

 green, half-climbing slu^b from 

 Chili ; closely related to the com- 

 mon Barberry. Propagated by 

 seeds, green cuttings, and layers 

 of mature shoots and branch es 



Berberis (Barberry). — ^A 

 genus of many . species, mostly 

 evergreen, erect or trailing 

 shrubs. A few species are de- 

 ciduous, like the common Euro- 

 pean Bai'beiTy {M. vulgaris), and 

 the American (B. Oanadensis). 

 Increased by seeds, by cuttings of the mature wood in autumn, by layers, 

 and some of the evergi-een species by cuttings of the subterranean 

 branches. The seeds of the species indigenous to cool chmates should 

 be washed from the pulp, mixed with sand and buried in the ground 

 out-doors over winter, and sown in a halt shady place in spiing, as the 

 young plants are very sensitive to the direct rays of the sun when they 

 first appear above ground. (See Ilex). 



Betula (Birch). — A genus of about thirty species of graceful decid- 

 uous trees and shrubs. Fully one-third of the known species are found 

 Sn North America, and some of them extending far northwardt Flowers
