To prosper, it must be planted in dry situations ; and, if in pots, they should be 
sheltered during winter in a cold frame. 
A. secundiflora. This is, also, a native of the south of Europe, whence it 
was introduced a few years ago. The flower-stem grows from six to nine inches 
high, and produces many small violet- coloured flowers. It has been cultivated 
successfully, treated in the same way as Cape bulbs. 
BARTHOLIN A. 
B. pectinata is a native of the Cape, and should be potted in sandy loam, and 
kept in the greenhouse. During the season of torpidity it should be kept per- 
fectly dry ; and, when beginning to grow, be placed in as light a place as possible. 
The flower-stem grows about six inches high, and bears one purple flower, with a 
fringed labellum. 
CALANTHE. 
C. densiflqra. This was found by Dr. Wallich on the mountains of Sylhet. 
It, therefore, requires the heat of the stove, and will grow freely in leaf mould and 
peat, or potted after the same manner as Epiphytes, with squares of peat soil 
The flowers are ochre-coloured. 
CALOCHILUS. 
C. campestris. This is a beautiful kind, the flower-stem growing about a 
foot high, and bearing six or eight flowers, the sepals of which are yellowish green, 
and the labellum purple, covered with rich brown hairs. It is a native of New 
Holland, where it was found growing on stony hills. It thrives in leaf mould and 
peat, and should be kept in the stove. 
CALYPSO. 
C. borealis. A small, but very pretty species. The flower-stem grows about 
three inches high, and produces a solitary flower, large for the size of the plant. 
The sepals and petals are a delicate rose colour, and the labellum of a pale reddish 
brown. It is a native of North America. The soil is leaf mould and peat, and it 
should be kept in an airy greenhouse, 
CYMBIDIUM. 
C. xiphiifolium. The flower-stem of this grows about nine inches high, and 
produces from four to six flowers, of an uniform yellowish green colour, without 
any spotting. These flowers possess a pleasant fragrance, particularly towards 
evening. It requires the heat of the stove ; and will thrive either in leaf-mould 
and peat well mixed, or peat cut in the same manner as for Epiphytes. 
CYPRIPEDIUM. 
C. arietinum. This is a native of North America. It grows about six 
or eight inches high, and produces at the top of the stem a single flower, the sepals 
of which are yellowish green, and the slipper-shaped labellum, white, striped with 
rose colour. Greater part of the Cypripediums thrive best in a mixture of sandy 
peat, and soil collected from the hearts of rotten trees ; but, in the absence of this 
last, mix with the peat a portion of leaf-mould and rotten saw-dust.
