CORYSANTHUS. 
exposed to the influence of the sun, 
it will not flower. Travellers in 
North America describe what are 
called there the Dog-woods, as vast 
forests of this tree, about twelve 
feet high, with their branches so 
interlaced as to prevent a gleam of 
sunshine from reaching their roots. 
Coronr' Lua.— Legumindse.—Or- 
namental shrubs, hardy and half- 
hardy, with bright yellow flowers, 
and pinnate leaves. C. E’merus,

grow in any soil or situation, and; 
as it will bear clipping without much 
wijury, it may he grown as a hedge- 
plant. It will grow in any garden 
soil, and is propagated by cuttings 
of the ripe wood or layers. C, glai- 
ca, which is a native of France, 
has bluish-green leaves and yee 
flowers, which are fragrant during 
the day, but lose their scent at night. 
It flowers early and freely, < 
though generally ene’ in the green- 
house, i it is very nearly hardy. The 
soil should be a sandy loam, mixed 
with a feurth part of vegetable 
mould, or rotten manure; and the 
pots should be well drained. 
propagated by seeds, which it ripens 
in abundance, or by cuttings in sand, 
under a bell-glass. 
Corra\s. — Ruticee. — Dwart | 
greenhouse shrubs, with leathery 
leaves, which are generally either 
brown or white on the under sur- 
face. The flowers are tubular; 
those of C. dlba, and C. rivfa, which | 
are white, being much less so than 
the others. Several new species, 
or hybrids, have been introduced 
since 1835; but they appear most | 
nearly allied to C. speciosa. All| 
the species and varieties flower 
abundantly ; producing in a green- 
house a constant succession of flow- 
ers from November to June. They 
of the | 
South of Europe, and the common- |

require an airy, but a somewhat 
shaded, situation. The pots should 
be well drained, and the soil should 
be heath-mould, mixed with a little 
loam. 
Corya’ntuEs. — Orchidaceae. — 
Helmet-flower. — C. macrantha, 
Lindl.—(Gongora macrantha, F1.) 
has a most singular red and yellow 
flower, part of which resembles a 
skeleton’s head, with the vertebre 
of the neck, and part two folded 
bats’ wings. The plant is grown 
in a pot in sandy peat, mixed with 
lime rubbish ; and the soil is raised 
above the level of the pot, as the 
flower-stalk hangs down from the 
rect. It is a native of the West 
Indies ; and like most other of the 
tropical Orchiddcee, it requires 
abundance of heat and moisture to 
| throw it into flower. 
Corypba’Lis.— Fumariéeee.—The 
_plants composing this genus were 
formerly considered to belong to 
Fumaria, the Fumitory, but they 
/have been separated on account of 
the different conformation of the 
‘capsule. C. glatica, which is the 
most common species, is an annual 
from North America, which may 
be sown at almost any season, and 
in any soil and situation. C. clavi- 
culdta, is a British climber, also an 
_annual, and pretty from the abun- 
| dance of its small white flowers. 
It is of very rapid growth, and it is 
useful in covering a trellis, &c., 
\from the number and dense habit 
of growth of its leaves. It grows 
best in a poor sandy or gravelly soil. 
| Other plants formerly included in 
this genus are now called Diclytra. 
Co'ryvLus—Amentdcee or Cupu- 
| lifere—The botanic name of the 
Hazel, Filbert, &c. The species 
are generally shrubs; but C, coltirna, 
the Constantinople nut, is a large 
ornamental tree.—See HazeEt.
