THE ORCHID REVIEW. 45 
CALANTHES AT ARUNDEL CASTLE, 
THE value of the deciduous Calanthes as decorative winter-flowering plants 
is well known, and when the numerous hybrid forms of recent years become 
better known they are likely to become still more popular. A figure of a 
very fine group is given in the Gardeners’ Chronicle for January 23rd (p. 57, 
fig. 15), grown at Arundel Castle, where the demand for flowering and 
ornamental leaved plants is great all the year round. The group is an 
excellent example of good cultivation, some of the plants of C. x Veitchii 
having as many as forty expanded flowers on some of the spikes, and 
so great is the vigour of some of the bulbs that four spikes are produced. 
Some were observed in which the flower spikes emerged from the extreme 
top of the pseudobulb. C. vestita rubro-oculata and C. y. luteo-oculata are 
also grown in great numbers, and do equally well. As many as five hundred 
spikes of these three varieties were in one house, arranged on a ground- 
work of ferns, producing a very fine effect. Owing to the absence of leaves 
at flowering time these plants look much better when arranged with various 
foliage plants. The secret of flowering them so well is to grow them 
strongly, and then give them a good rest to mature the bulbs properly. It 
is not everyone, however, that succeeds with them, and it would be 
interesting if some of our readers who grow them well would let us know 
their method of treatment. 
ODONTOGLOSSUM CRISPUM. 
Tue following interesting paper by Mr. Robert Thompson, of Bogota, is 
reproduced from the Budletin of the Botanical Department, Jamaica, for 
November, 1896, where it appears under the title, ‘‘ Memorandum relative 
to a valuable species of Orchid recommended for Naturalisation in Jamaica’’ 
(Pp. 253-255) :-— | | 
This species of Orchid is indigenous to the western slopes of the Eastern 
Cordilleras of the Colombian Andes. Its habitat extends from about 3° to 
5° north. 
The flowers of this species are extremely variable, ranging from inferior 
types or forms which are rejected by the Orchid grower, to forms comprising 
the most popular of all Orchids. The famous forms are confined to the 
centre of the area of distribution, i.e., the Pacho district. The — 
forms are characterised in general by narrow floral segments—“ starry ’ 
type. The fine forms are distinguished by broad floral segments, thus in 
Contradistinction to the narrow “ starry ” forms. The flowers of the fine types 
ate otherwise remarkable in their varietal diversity; numerous shades of
