rmediate house, with cooler rest for
the deciduous and highland species. The genus is one of the most varied
and remarkable, and full collections of them are grown by some amateurs.

~Calanthe.~--These are terrestrial Orchids, which may be divided into two
sections--the evergreen of the _C. veratrifolia_ class; and the
deciduous, comprising _C. vestita_, _C. Veitchii_, and numerous other
species and hybrids which are extensively grown for flowering in winter.
Pot them in a compost of one-half fibrous loam, one-fourth
Sphagnum-moss, and one-fourth leaves, with a sprinkling of sand. Rest
the deciduous section dry after flowering, and repot them when growth
commences in spring. Water liberally with occasional applications of
liquid manure, which should be withheld when the growth is completed.

~Catasetum.~--The Catasetums are curious, epiphytal Orchids, which should
be grown in baskets, or Orchid pans, suspended in the intermediate
house, and treated in a similar manner to the deciduous Dendrobiums.
They require a long, dry rest after the growths are completed. All the
species are worthy of cultivation, _C. Bungerothii_, _C. splendens_, and
_C. macrocarpa_ being the more showy kinds.

~Cattleya.~--One of the largest, most varied, and florally beautiful
genera of Orchids. The plants should be potted as recommended for
epiphytal Orchids, and they should be grown in the intermediate house.
The _C. labiata_ section, including _C. Gaskelliana_, _C. Mossiae_, _C.
Mendelii_, _C. Dowiana_ and its variety _aurea_, _C Warscewiczii_, _C.
Warneri_, and _C. Schroederae_ in succession, produce flowers for the
greater part of the year. _C. citrina_ should be grown in the cool
house, suspended from the roof. Cattleyas and Laelias are impatient of a
close atmosphere, and therefore the proper ventilation of the house in
which they are grown is an important matter. _C. Trianae_, var Hydra, is
illustrated in Plate IV.

~Chysis.~--A small genus of intermediate-house epiphytes, comprising _C.
bractescens_, white; _C. aurea_ and _C. laevis_, yellow and red; _C.
Limminghei_, and several hybrids.

~Cirrhopetalum.~--A section of Bulbophyllum, of similar habit, and
requiring similar treatment. The curiously formed flowers frequently
have the upper segments fringed, and the lateral ones approached and
continued into slender tails.

~Cirrhaea.~--Allied to Gongora, and requiring similar treatment.

~Cochlioda.~--A compact-growing genus to be gr
