 in sand in a close frame, with bottom-heat. Fibrous 

 loam, peat and sand. 

 B. burma'nica (Burman). Yellow. June. Burma ; 



Malaya. 1823. 



BOUGABfVTLLEA. (Named after de Bougainville, a 

 French navigator. Nat. ord. Nyctaginaceae.) 



Very showy, greenhouse climbers, especially those 

 which flower freely every year under ordinary treat- 

 ment. They flower best when planted out in a border 

 and trained up the rafters or pillars. After the end of 

 October they should be kept dry at the roots to thoroughly 

 ripen the wood, and then cut hard back to the main 

 stems early in the year. Propagated by cuttings of 

 half-ripened shoots in sand in a close frame with bottom- 

 heat. Plants to be flowered in pots should be started 

 in a stove and afterwards placed in the greenhouse. 

 Liquid manure may be given with advantage when in 

 full growth. The soil for borders may consist of three 

 parts turfy loam to one of leaf-mould and sufficient sand 

 to make it porous. Give plenty of ventilation when in 

 full growth.

BOX (Bu'xus sempervi'rens) is noticed by the gardener 

 chiefly as a plant suitable for edgings. For this purpose 

 it is neat ; but it is an exhauster of the soil more than 

 any other that can be so employed, and is a favourite 

 lurking-place for the snail. For plants that may be 

 substituted, see EDGING. The best months for planting 

 Box are September and February. Small-rooted slips 

 are employed, and are planted against the perpendicular 

 side of a small trench, along the edge of the border or 

 bed they are desired to bound. The best month for 

 clipping Box is June, and it should be done in showery 

 weather. With great attention to not injuring the roots, 

 and to washing earth in among these in their new posi- 

 tion, large Box-trees or bushes have been moved in May, 

 June, and July.

 gated by division in spring. Ordinary garden soil of a 

 light character.
