108 THE ORCHID REVIEW. 
that Messrs. Sander did not include Sikkim in their interesting note on the 
distribution of C. insigne at page 15 of the present volume. Reverting to 
Cymbidiums, I suspect that this is not the only natural hybrid in the 
genus, for another very curious form is known, and C. X eburneo- 
Lowianum is also said to have been found wild, though I should like to 
know more particulars.

CULTURE OF CALANTHES. 
A USEFUL note onthe Culture of Calanthes is given by Mr. A. Williams, 
Keele Hall Gardens, in a recent number of the Gardeners’ Chronicle. The 
plants, after receiving a dry rest on the shelf of an Intermediate House, will 
now require potting. A suitable compost consists of one part fibrous loam, 
broken by hand, one part peat, one of leaf-mould, some sphagnum moss 
chopped fine, a small quantity of dried cow or horse dung, a few small 
crocks, and somesilver sand. These should be mixed well together, and the 
mixture made warm before using. The most suitable sized pot is one of six 
inches in diameter, but for small pseudobulbs and certain purposes slightly 
smaller ones may be chosen; the larger bulbs going into the bigger pots. 
The pots should be half filled with clean crocks, over which some sphagnum 
moss must be placed, then the compost. One pseudobulb should now be 
placed in the centre of the pot, and some of the compost placed round it, 
which should be pressed in firmly, filling the pot nearly to the rim, and 
finishing off with a dash of silver sand. The pots should be placed in the 
stove, on a shelf near the glass, and the outsides should be sprinkled daily, 
but no water should be afforded the pseudobulbs till rooting begins. When 
the roots have reached the sides of the pots, some chopped sphagnum moss 
should be placed on the surface of the soil, into which the roots will pass in 
a short space of time. As the pseudobulbs begin to swell out, water may 
be afforded twice a week, and liquid manure occasionally ; shading the 
plants from the direct rays of the sun. With this sort of treatment Mr. 
Williams has had spikes with from forty to fifty expanded flowers on them. 
DENDROBIUM x AINSWORTHII AS A WILD PLANT. 
In recording the occurrence of a plant of Dendrobium x Ainsworthii 
among importations of D. nobile, about a year ago, I remarked that it was 
“not likely to remain an isolated example” (ante, vii., p. 99). Another 
plant has now flowered in the collection of Arthur E. Pattinson, Esq-, 
7, Faulkner Square, Liverpool, among some imported pieces of D. nobile, 
purchased from Messrs. John Cowan and Co., of Gateacre, and was 
immediately recognized as a natural hybrid. The flowers sent have the
