climber for quickly covering a south, south-west or a west wall ; 
or even for clothing a pergola. It is a vigorous grower and 
altogether a most desirable climber. The only hardy species is 
A. Sipho, a native of N. America, and a member of the Birth- 
wort order (Aristolochiacese). No special soil is required. 
Plant in autumn or early spring. The shoots must be kept 
trained, as they grow, to the wall. The only other attention 
needed will be to cut out dead and weak growths. 
Berberidopsis (Coral Barberry). — An evergreen climb- 
ing and flowering shrub, a native of Chili, and a member of the 
Barberry family (Berberidaceae). The only species grown is 
B. corallina. This has heart-shaped, spiny leaves, and bears 
coral red or crimson flowers in drooping clusters at the apex 
of the young shoots in summer. It is only adapted for 
culture against east or west walls in the warmer parts of 
the country. Requires a peaty soil. Plant in September or 
April. No pruning is needed. Increased by cuttings of the 
old wood furnished with a “ heel,” inserted in sandy peat in 
a cold frame in September ; also by layering the shoots in 
summer. 
Boussingfaultia (Madeira Vine). — A hardy climbing 
perennial, belonging to the Spinach family (Chenopodiaceae). 
The only species is B. baselloides, and this produces annual 
shoots upwards of 20ft. long, the leaves being fleshy, and the 
flowers small, white and fragrant. The roots are thick and 
fleshy. Suitable for covering trellises quickly in summer, or 
for trailing over dry banks. Plant in spring. Increased by 
tubercles removed from the axils of -the leaves and planted in 
the soil. Native of Ecuador. 
Calycanthus (Allspice Tree). — Hardy deciduous shrubs 
bearing fragrant flowers, natives of N. America, and belonging 
to the Nat. Ord. Calycanthaceae. C. floridus (Carolina All- 
spice) grows 6 to 10ft. high, and bears crimson-maroon flowers, 
deliciously scented, in May. C. occidentalis (Western All- 
spice) grows 6 to 8 ft. high, and bears large dark crimson 
flowers in June. This produces a less number of flowers than 
C. floridus, but they are nicely scented. Both do well in shady 
sheltered shrubberies where the soil is moist. C. occidentalis 
also makes a fine lawn shrub. We have seen it do well, too, on 
south and west walls. Plant in autumn. Propagate by layering 
the shoots in summei. 
Calystegfia (Bearbind). — A genus of climbing hardy 
perennials with fleshy roots, and popularly called Convolvu- 
luses. They belong to *he Nat. Ord. Convolvulaceae. C. 
hederacea (Syn. C. pubescens) is a Chinese species with
