loam and peat, to which, sand and powdered charcoal are freely added, potting firmly. 

 Well-established plants require to be re-potted every year, doing this directly after 

 top growth ceases ; but avoid overpotting. Top all loose growths with a view to 

 keeping the plants in a bushy state. During the summer they ought to be arranged 

 either in shallow cold pits or in frames raised off the ground by bricks or flower-pots, 

 shading from strong sunshine for a time, and sheltering from drenching rains, at all 

 other times drawing off the sashes. Transfer to an airy greenhouse in September. 

 When well rooted, they should be freely watered during the summer, and carefully 

 during the winter.

browallia. — Browallia elata, native of Peru, is a blue flowering annual that is 

 admirably adapted for pot culture, and may easily be had in a showy condition during 

 the summer, late autumn, and winter months. Plants raised by sowing seed in gentle 

 heat in March will flower in the summer, but for a late display more seed should be 

 sown in July. Establish three seedlings in each 5-inch pot, using a moderately rich 

 loamy compost, and grow them in frames. Top two or three times, feed the plants 

 with liquid manure, and syringe occasionally to keep down red spider. No further 

 shift need be given, unless extra large plants are required. Transfer the plants to 

 their flowering quarters — a light greenhouse — in September. The beautiful plant 

 known as Browallia Jamesoni will be alluded to under " Streptosolen." 



burtonia. — These plants are heath-like in character, and, when properly managed, 

 attractive. B. pulchella — syn. B. scabra — height 2 feet, flowers purple, April ; and 

 B. villosa, height 18 inches to 2 feet, flowers purple, May, are both natives of West 

 Australia. They are propagated by cuttings, inserted in sandy peat under a bell glass, 

 in a cool house. When rooted, they are placed singly in 2 -inch pots, using a mixture 

 of equal parts of loam, peat, leaf soil, and sand, draining the pots very carefully. 

 Small shifts should only be given, and the potting must be done firmly. In other 

 respects treat similarly to Ericas, which see.

callistemon. — -The Callistemon is included among those old-fashioned, hard- 

 wooded plants that have largely given place to more easily grown showy kinds, yet 

 meriting better treatment. The three species most frequently grown are C. linearis 

 (New South Wales), height 4 to 6 feet, flowers scarlet, June ; C. salignus (Australia), 

 height 4 to 6 feet, flowers straw-coloured, June to August; and C. speciosus (West
