 and there often cultivated, the bark being used for 

 paper-making. Ornamental trees with broad, round 

 heads, but under culture often shrubby, of vigorous 

 growth when young, and effective by its large, often 

 deeply lobed foliage, not hardy north oronly in very shel- 

 tered positions. They thrive best in rich, somewhat 

 moist soil and sheltered positions. Prop, by seeds, sown 

 after maturity or in spring, by greenwood cuttings under 

 glass, or by cuttings of ripened wood, kept in colder 

 climates during the winter in the greenhouse ; also by 

 root-cuttings and layers. Budding in summer or graft- 

 ing in early spring in the greenhouse is sometimes 

 practised. Known as Paper Mulberries.

BROWALLIA (after John Browall, Bishop of Abo, 

 Sweden). SolanAccw. A genus of about 10 South 

 American annuals, with abumlant Miir. \ io|,.f or white 

 flowers. The seeds can be sown in tlio opon Kordir, Imt 

 for the sake of the earlier bloom it i- I,, ti, r to start 

 them indoors in early spring ami tran-plani into the 

 open about May 15, where they will bloom ]ii.itiisily all 

 through our hot, dry summers, and uuiil trust, tln-y 

 can be grown in poorer soil than most hall' hanlv an- 

 nuals, and make excellent bedding jilants. They are 

 also used for winter decoration, the seeds being sown in 

 midsummer, earlier or later according to the size of 

 the specimens desired. They should be placed near the 

 glass and frequently stopped, in order to produce com- 

 pact plants. T.nT-c-n -|,n,.iTnfns are excellent for cutting, 

 and small !■ ' ■! .i -bould be grown more com- 

 monly by lli ill: .locoration at Christmas. It 

 is even pos-i ;.:i ,', .\ .ring plants from the open 

 before the lir i li > i oi autumn and pot them for con- 

 servatory decoration, though the flowers are likely to 

 become successively smaller. Blue flowers are rare in 

 winter, and Browallias are especially desirable for their 

 profuse bloom all through winter and early spring. 

 The flowers are, however, likely to fade, especially the 

 purple ones. In the names of the early species, Linnaeus 

 commemorated the course of his acquaintancship with 

 Browall : elata, reflecting the exalted character of their 

 early intimacy : f/emissa, its rupture ; and fl7ie«afa, the 

 permanent estrangement of the two men.
