Boronia — continued. 

 When in the cutting state, water must be very carefully 

 given around the rim of the pot, without taking- off the 

 glass. If placed in a temperature of about SOdeg"., and 

 shaded from bright noonday sun, they soon root, when 

 they may be potted off singly into small pots, and plunged 

 in sawdust, or cocoa-nut fibre refuse, in which situation 

 but little water is needed. Pinching repeatedly, when 

 young, is the only means to secure good ultimate growth. 

 Air must be given on all possible opportunities.

BOKRBRIA (named after William Borrer, F.L.S., a 

 profound botanist and cryptogamist). Ord. RiihiacecE. A 

 large genus of stove herbs or sub-shrvibs, now referred to 

 Spei'wacoce. Flowers small, white, rarely blue, disposed 

 in verticiUate heads, in the axils of the leaves, or on the 

 tops of the branches, rarely cymose or corymbose. Leaves 

 opposite, or the young ones disposed in fascicles in the 

 axils of the old ones, and therefore appearing verticiUate ; 

 stipules joining with the petioles, more or less sheathing, 

 fringed by many bristles. Stems and branches usually 

 tetragonal. The species are of easy culture, thriving in 

 a light soil. Cuttings of the perennial kinds strike root 

 readily in the same kind of soil, in heat. The annual 

 kinds require a similar treatment to other tender annuals. 



B* Stricta (straight). A dwarf shrub, but closely allied to the 



next species. Porto Rico.

lanceolate, acuminated, opposite, but appearing verticiUate from

BOSCIA (named after Louis Bosc, a French professor 

 of agricirlture). Syn. Podoria. Ord. Capparidacece. A 

 small genus of stove plants, requiring a soil of lumpy, fibry 

 loam and peat. Propagated by cuttings of firm wood, 

 placed in sand, binder a glass, in heat. 



B. senegSllsusiS (Senegal). Jl. white, small, apetalous, corym- 

 bose, h. 3ft. Senegal, 1824. An unarmed evergreen shrub 

 (L. E. M. 395.) 



BOSSIJEA (named after M. Bossier Lamartini&re, a 

 French botanist, who accompanied the unfortunate La 

 Peyrouse round the world). Ord. Leguminosce. A genus 

 of elegant Australian greeidiouse slirubs. Flowers yellow, 

 axillary and solitary, the base of the vexillum or the keel 

 generally blotched or veined with purple. Leaves simple, 

 of various forms. A mixture of turfy loam, leaf mould, 

 peat, and sand, with very free drainage, suits these plants 

 best. Half-ripened cuttings will root freely if placed in a * 

 pot of sand with a bell glass over them, in a cool house. 

 Seeds should be sown, in March, on a slight hotbed. 



B* Cinerea (ashy-grey), jl. yellow, the vexillum furnished with
