156 A FEW HINTS ON THE MANAGEMENT OF TERRESTRIAL ORCHIDEJE. 
and loam, requires constantly the heat of the stove, and is propagated by division 
of the roots. 
C. ensifolium is a native of China, and was introduced many years ago. The 
flower stem grows from two to three feet high, and bears from four to eight fragrant 
flowers. The sepals and petals are yellowish green, with brownish purple veins, 
and the labellum is spotted with purple. It requires the same treatment as the 
last. 
C. Sinensis. — This is also a native of China, whence it was introduced in 
1793. The flower stem grows from a foot and a half to two feet high, and produces 
from six to ten fragrant flowers. Sepals and petals of a brownish purple, and the 
labellum is of a greenish yellow, and spotted with purple. 
C. aloifolium. — A native of the East Indies, where it grows upon trees, 
whence it was introduced in 1789. It is a very handsome species. The flower 
stem springs from the root, and hangs gracefully pendent, is from one foot to 
eighteen inches long, and produces many flowers. Sepals and petals pale purple, 
striped down the centre of each with a longitudinal dark bar. Our plants thrive 
well in turfy peat soil, treated nearly after the manner of Epiphytes. All the 
species of Cymbidium are stove plants, and are propagated by division of the roots. 
CYPRIPEDIUM. 
C. pubescens. — All the plants of this genus are very beautiful, the pubescens 
is elegant ; the flower stem grows about a foot high ; the sepals are yellowish green, 
shaded with brown, and the slipper-shaped labellum is a rich golden yellow. It is 
a native of North America, where it is said " to grow on the sides of stony hills 
that are covered with underwood and small trees, which admit the sun through 
their leaves and branches to the ground It is always considered rather difficult 
to cultivate, and although it is a perennial it often dies without any apparent cause. 
The best soil for it is equal parts of sandy peat and rotten vegetable mould found 
at the bottom of a hollow tree ; but if this last cannot be obtained, mix a portion 
of rotten sawdust with light loam. It is propagated by separation at the roots. 
C. insigne. — This is a splendid species of Cypripedium , perhaps equalled by 
none yet discovered, certainly not surpassed ; it is a native of Nepal, and was in- 
troduced by Dr. Wallich, some years ago. The sepals are yellow green, spotted 
and striped with rich brown ; and the labellum is orange yellow, tinged on the 
outside by the same rich brown. It requires the stove, and may be planted in the 
rotten soil from the bottom of a tree, mixed with equal parts of sandy peat, and 
may be increased by separation at the roots. 
C. spectabile. — This, in point of beauty, is little behind the last, and the 
flower is nearly as large. It is a native of the bogs and low meadows of North 
America ; it has been grown in this country many years, but is rather difficult to 
keep. It is perfectly hardy, and should be potted in the same compost as recom- 
mended for the pubescens and spectabile. The sepals are pure white, very deli- 
cate, and the labellum a bright soft crimson.
