THE ORCHID REVIEW. 35 
A series of articles on “ Natural Hybrid Orchids,” by Mr. R. A. Rolfe, 
is commenced in the Gardeners’ Chronicle for January 25th, from which it 
appears that as long ago as 1878 Visiani had called attention to the probable 
hybrid origin of Orchis x suaveolens, now known as Nigritella X suaveolens. 
Phalznopsi int dia was the first recognised hybrid among tropical 
Orchids, and Lindley correctly indicated its origin and parentage in 1853, 
before any artificially raised hybrid had flowered. 
Catasetum x splendens punctatissimum, described at page 85 of our 
last volume, is characterised by having the petals densely covered with 
minute reddish-brown dots on a yellowish ground. A similar form has 
appeared in the establishment of Mr. W. Bull, of Chelsea, except that the 
minute dots extend round the limb of the galeate lip. 
A good form of Cypripedium x Williamsi comes from the collection 
of F. M. Burton, Esq., of Gainsborough. It is derived from C. villosum g 
and C. venustum ¢, and was exhibited at a meeting of the R. H. S. on 
February r2th, 1895, under the name of C. x refulgens (Gard. Chron., 
1895, i., p. 210). It most resembles the former parent. A second plant of 
the same name is a synonym of C. x Adonis, and owing to the identity of 
name the present one has also been confounded with this (Hansen Orch. 
Hyb., p. 131). 
A very curious flower of Cypripedium Boxallii from the collection of 
Reginald Young, Esq., Sefton Park, Liverpool, has almost all the usual 
purple-brown absent from the lip, while the petals and dorsal sepal are 
typical in colour. A good ordinary form is sent with it. Messrs. Hurst & 
Son, Burbage Nurseries, Hinckley, also sends the latter, together with 
a fine flower of C. B. atratum, in which the dorsal sepal is very large 
and very richly coloured.

ANGRAECUM BISTORTUM. 
A PLanr of this singular little species (supra I., p. 178) has appeared in the 
collection of E. H. Woodall, Esq., of Scarborough. Mr. Woodall remarks 
that it branches freely from the lower part of the stem, making quite a pretty 
plant when in full flower. It is a native of Lagos, and originally flowered 
at Kew in January, 1892. Its great peculiarity is the way the tip of the 
spur usually remains tucked into the axil of the bract, thus compelling the 
spur to double up into a loop as it elongates. This, however, is not 
invariably the case, for if the spur frees itself it then becomes straight, and 
the question is which is the normal condition.
