Z10 THE ORCHID REVIEW. 
One group which in many collections occupies a very prominent 
position has yet to be mentioned, namely, the Cypripediums. They are not 
unrepresented, it is true, but their number is comparatively small. The 
fact is the majority of them are not liked. Those which vary a little from the 
stiff and formal shape, and from the endless mixtures of green and brown 
so common in the genus, find a place. There is a nice batch of plants of 
the niveum section, as C. niveum and C. bellatulum; C. Stonei also is 
included. The remarkable New Guinea species, C. Chamberlainianum, 
which was named after Mr. Chamberlain, is also appropriately represented 
by one of the best pieces imported. Selenipedium Schlimii, as well as S. x 
Sedeni and its pretty varieties, are also among the few that find favour with — 
Mr. Chamberlain. | 
A multitude of names could be added to the account of this choice ant 
valuable collection, but a mere catalogue would only be wearisome. Many 
of the species are grown in quantity, and poor forms are not allowed to 
remain. The Dendrobiums, Odontoglossums, Cattleyas and Leelias, and 
the Phalenopses are the pride of the collection, and most of the other 
things which are included are of a decidedly showy character. 
DENDROBIUM x BARBATULO-CHLOROPS. 
Natural hybrids in the genus Dendrobium are by no means commoh 
The best known example is D. x crassinodi-Wardianum, whose intermediatt 
character is unmistakable. Two or three others have been reported, but 
these are, to say the least, doubtful. Last year, however, a second example 
came to light, in the collection of Major-General E. S. Berkeley, Spetehley: 
Bitterne Park, Southampton, and the plant is again flowering with him. 
is a natural hybrid between D. barbatulum and D. chlorops, which species 
grow together in hundreds in the Deccan Peninsula, S. India. It has 3° 
unmistakable combination of the characters of the two parent species. The 
flowers are white, much like those of D. barbatulum, with a similar acute 
Spur, but the side lobes of the lip are wholly green, as in D. chlorop® 
instead of being lined with purple, as in the other species. The hairy dis¢ 
most resembles that of D. barbatulum. It isa very interesting plant.
