BROMELIA. 



A genus of herbaceous perennials (t>rd. Brom- 

 elincea?) that must be grown in the stove, where 

 they present a handsome appearance. It is im- 

 portant that the soil be kept somewhat dry during 

 the winter months. The stock may be increased 

 from suckers in loam. A rich compost in which 

 loam predominates is most suitable. 



Principal Species : 



bracteata (xee JEchmea.). Pinguin, 3', Mch., red 

 (syn. Binotii). 



Other Species : 



Binotii (see Pinguin). Fernandas, 2', Aug., yel., 



fastuosa, 4', Aug., pur. red. 



(syns. antiacantha and laciniosa, lil., leaves 4' to 



Karatas antiacantha) . 5' long. 



sylvestris, 3', Jy.. crim. 



BROMHEADIA. 



A slender, reed-like Orchid (prd. Orchidaceas), 

 found in swampy places in islands of the Malay 

 Archipelago. It is not difficult to cultivate in peat 

 and sphagnum in a warm stove, where at no season 

 of the year should the roots become dry. It rarely 

 flowers, and consequently is seldom grown. 



Principal Species : 



palustris, 1J', My., Je., wh., lip wh., veined vio. 



BROMUS. 



The genus Bromus is a fairly large one, but the 

 species generally grown in gardens, and the 

 most ornamental, is brizaeformis, a pretty biennial 

 Grass (prd. Graminese), which is useful in the 

 garden or among cut flowers, or for drying for 

 vases in winter. It grows about 2' high, and has 

 pretty spikes of drooping flowers like those of 

 the Brizas. It should be sown in the open at the 

 end of June or beginning of July. 



BRONGNIARTIA. 



A small genus of evergreen shrubs (prd. Legu- 

 minosEe) requiring greenhouse treatment. Cuttings 

 root freely in sand under a bell-glass. A mixture 

 of fibrous peat, loam, and coarse sand is suitable. 



Principal Species : 



podalyrioides, 1', Sep., sericea, 1', Sep., pur. 

 flesh. 



BROOM. 



The Brooms are very ornamental in the garden 

 or shrubbery, and can hardly be used amiss on 

 rockeries of any size. The plants popularly known 

 by this name include Cytisuses, Genistas, and 

 Spartiums, and these will be found described in 

 detail under their respective titles. They are 

 generally very decorative, and comprise plants of 

 much diversity of habit, some forming tall bushes 

 of graceful foliage, and others being of trailing 

 habit and adapted for hanging over rockwork. 

 Among the best of the Brooms is Cytisus sco- 

 parius, which has given the brilliant variety 

 andreanus. C. prfccox, supposed to be a hybrid, is 

 very beautiful, and the white Portuguese Broom, 

 Cytisus albus. is a favourite with all. Many of the 

 Brooms make fine pot plants, and can be gradually 

 forced so as to bloom early under glass. 



BROOM, SPANISH. 



This is Spartium junceum and Genista hispanica, 

 which see for particulars. 



BROSIMUM. 



This genus (ord. Urticacese) has great economic 

 value. Its fruit is eaten boiled and roasted, 

 and its young branches are valuable food for stock. 

 The gummy exudation is made into rubber. Prop- 

 agation is effected by cuttings inserted in a 

 propagating case. Rich loam is the best soil, and 

 a stove temperature is essential. Galactodendron 

 is the celebrated Cow Tree of South America, 

 yielding a sap closely resembling cow's milk, and 

 as agreeable and valuable for food. 



Principal Species : 

 Alicastrum, 6', My., gm., Humboldtii (tee Galacto- 



Bread Nut. dendron). 



Galactodendrou, 100', miorocarpum (see Alicas- 



My., grn. trum). 



BROUGHTONIA. 



A small genus of Orchids (ord. Orchidacese) 

 which produce attractive flowers when grown in a 

 warm structure. Propagation may be readily 

 effected by division ; and the plants thrive best 

 on blocks of wood, with a little sphagnum moss, 

 and must be accorded a very light position. Al- 

 though three or four species are known, only one, 

 viz. sanguinea, is of material value ; the others 

 are rarely cultivated, though lilacina is occasionally 

 imported. 



Principal Species : 



lilacina, 1 J', Je., Sep., ro. sanguiuea, 1J, Jy., Aug., 

 liL (syn. Lajliopsis do- crim. 



miugeusis). 



BROUSSONETIA. 



A genus of Japanese trees (ord. Urticaceas), 

 useful for their handsome leafage ; they are not 

 perfectly hardy in the colder portions of this 

 country. Propagation is by autumn cuttings, and 

 seeds when procurable. They will grow in any 

 fertile soil. 



Principal Species : 



papyrifera, 12', Ap., grn., Paper Tree or Paper 

 Mulberry; cucullata, laciniata, and macrophylla are 

 all varietal forms of papyrifera 



BROWALLIA. 



These plants (ord. Solanacese) have been cul- 

 tivated in this country for many years, but, 



Broom (see llesom). 



Brotera of Cavanilles (see Melhania).
