Boronia continued. 



When in the cutting state, water most 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.

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

 profound botanist and cryptogamist). OBD. Rubiaceaf. A 

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

 Spermatoce. Flowers small, white, rarely blue, disposed 

 in verticillate heads, in the arils 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 verticillate ; 

 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 pirm'lar treatment to other tender annuals, 



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



next species. Porto Bico. 

 B. verticillata (whorled-flowered). A. white. July. L linear 



lanceolate, acuminated, opposite, but appearing verticillate from 

 the fascicles of young leaves in the axils. A. 2ft West Indies, 

 1732. 



BOSCIA (named after Louis Bosc, a French professor 

 of agriculture). SYN. Podoria. OBD. Capparideoe. A 

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

 loam and peat Propagated by cuttings of firm wood, 

 placed in sand, under a glass, in heat.

BOSSLEA (named after M. Bossier Lamartiniere, a 

 French botanist, who accompanied the unfortunate La 

 Peyrouse round the world). OBD. Leguminous. A genus 

 of elegant Australian greenhouse shrubs. 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 vexUlum furnished with 

 a purple circle at the base, and the keel dark purple. May. 

 L nearly sessile, cordate acute, ending in a spiny mucrone, 

 scabrous above, but pilose on the nerves beneath, with recurved 

 margins. Branches terete, crowded with leaves, villons. A. 1ft
