A FEW HINTS ON THE MANAGEMENT OF TERRESTRIAL ORCHIDEiE.

It grows freely with us in loam and peat, and is increased by separating the bulbs. 
This plant requires a winter like the B. gracilis. 
B. Verecunda is a native of the West Indies, and was introduced many years 
ago ; it very much resembles the last in both its manner of growth and colour 
of the flowers ; the flower stem, however, grows three feet or more high ; the plant 
is of stronger growth, and the colour of the flower of a darker purple. It requires 
the heat of the stove, and is propagated by separating the roots just after the season 
of torpidity. Winter it like the B. gracilis. 
B. Reflexa, — This species we do not possess, unless some of our unnamed 
species should prove to be it. The sepals and petals are greenish yellow, tinged 
around the borders with purple, and marked with purple veins, and the labellum is 
purple. It requires the same kind of treatment as other Blelias, and may be pro- 
pagated in the same way. 
BONATEA. 
B. Speciosa is a native of the Cape of Good Hope. The flowers are green and 
slightly fragrant, without any thing striking as regards ornament, but very remarkable 
in structure. We keep our plant in a cool part of the stove, but there is no doubt 
it would grow in the greenhouse. It should be potted in sandy loam and peat, and 
propagates slowly by division of the roots. After the tops are dead it should be 
placed in a cool situation, where it will receive no water for three months, after- 
wards it should be repotted, and placed again in the stove. 
CALANTHE. 
C. VERATRiFOLiA is a fine showy species, bearing a pyramidal spike of pure 
white flowers, two feet or more high. It is a native of the East Indies, whence it 
was introduced in 1819. It requires to be placed in a cool part of the stove, and 
should be potted in sandy loam and peat ; and at the season of torpidity should be 
kept cool, and be seldom watered. The mode of propagation is by dividing the 
root. There is one particular respecting its culture which must not be omitted, 
viz. that it does not flourish in a system of damp treatment, but the flowers are 
damped and do not open freely, neither do they appear a clear white. To avoid 
this, place the plants in an airy light part of the stove, where there is little humidity, 
and never saturate it with water. 
CALOPOGON. 
C. PULCHELLUS IS a vcry hardy greenhouse plant, a native of North America, 
introduced to this country many years ago. The flower stem grows from a foot to 
a foot and a half high, and bears three or four purple flowers. It will grow in 
peat and loam, and may be propagated by separating the tuberous roots. 
CYMBIDIUM. 
" C. LANCIFOLIUM is a native of the East Indies, whence it was introduced in 
1822. The flower stem grows erect, and produces from four to six flowers; sepals 
white, tinged with yellow ; petals yellowish white, tinged with rose-colour ; lip of 
the same colour, but spotted with crimson This plant thrives in a mixture of peat
