CALLISTACHYS. 



A name given to a small section of Ox.vlobium 

 (ord. Leguminosa;), and differing from the type 

 chiefly by having the pods divided by partitions 

 between the seeds, though the character is in- 

 constant. They are small shrubs with simple 

 leaves and yellow or red and purple flowers. Now 

 referred to Oxylobinm. 



Principal Species : 



cuneifolia (.w Isotropis 



striata).

ata, and retusa (-vr Oxy-

CALLISTEMON. (BOTTLE BRUSH TREE.) 

 About a dozen species of tall shrubs or small 

 trees (ord. Myrtacese). The flowers are in dense 

 spikes. They are notable for the long, yellow or 

 scarlet stamens, which give them the appearance 

 of a bottle brush. The leaves are simple, evergreen, 

 and leathery. Propagated by seeds sown in a warm 

 pit or stove, and treated like Grevillea robusta in 

 their earliest stages. Cuttings of shoots just 

 getting firm root in pots of very sandy peat under 

 a hand-light in early summer. Equal parts of fibrous 

 loam and peat, with a good dash of sand, will make 

 a suitable compost. Some cultivators add lumps 

 of charcoal. Make the soil firm whether in pots or 

 tubs, water liberally in summer, but keep them 

 fairly dry in winter in a warm greenhouse ; those 

 which flower early might have a temperature of 50 

 in spring.

CALLISTEPHUS. 



Half-hardy annuals (ord. Composite), the chief 

 interest of which lies in the numerous garden 

 varieties, the latter being superior to the species.

CALLITRIS. 



A genus of Coniferous trees (ord. Coniferse) 

 allied to Thuya and Cupressus. They may be 

 propagated by seeds, or by cuttings of the half 

 mature shoots in pots of sandy soil, kept in frames 

 from which frost is just excluded in winter. Sandy, 

 fibrous loam will suit them. They may be grown 

 in a cool greenhouse, intermediate house, or stove 

 with equal freedom, and are often grown as fine 

 foliage plants on account of their elegance.

cupressiformis (see rhom- 

 boidea).

CALOCHOKTUS NITIDUS (see p. 159). 



CALLIXENE. 



A half-hardy shrub allied to Lapageria (ord. 

 Liliaceae), of dwarf, erect habit, only 18" high 

 when grown in sheltered places out of doors. It 

 has short, spreading side shoots, small evergreen 

 leaves, and small white flowers. Propagation may 

 be effected by taking off rooted suckers. Peaty 

 soil suits, such as is used for Lapageria. Now 

 referred to Luzuriaga. 



Principal Species : 



polyphylla (see Luzuriaga erecta). 



CallitJiauma (see Stenomeumt).
