chilon, in which the two sexes do not show much diversity, except in the 
female having a short stout column, with a pair of triangular wings. It is 
in the section Heteranthe that the great diversity is seen, and in the one 
now figured the difference is as oe in colour as in shape. Well might 
Lindley say that ‘“ notwithstanding . . the unquestionable authority of 
Mr. Bateman, there were many persons, well skilled in the habits of 
Orchidacez, who felt convinced that some mistake had been made,” though 
he himself little dreamt of the real explanation, or he would not have spoken 
of ‘‘all ideas of species and stability of structure in the vegetable kingdom 
being shaken to their foundation.” 
Bateman’s own remarks on the subject, written over half a century after 
the event, are extremely interesting, and may be found in an earlier volume 
(O.R., vi: p. 57). 
It will be observed that the photograph showing the male inflorescence 
ison a slightly smaller scale than that showing the female, this being on 
account of the length of the raceme, and even now the five lowermost 
flowers have been omitted. The light back-ground was used to show up the 
purple BOWERS, and the dark one to show up the green flowers.

CYPRIPEDIUMS will soon be making a good show, and will see us well 
through the worst of the dull days. With a little care the flowers will 
keep in perfection for ten or twelve weeks without injury to the plants, pro- 
vided, of course, the plants are in good health, and then will do for a fort- 
night or so cut for decoration. Now that hybrid Cypripediums are so 
plentiful, a great variety can be grown in a small house, and the colours 
range from almost black to white, although the darkest and the lightest are 
species, namely, C. Charlesworthii Richard Moore, and C. bellatulum 
album. Growers who do not go in for choice varieties can get a good 
range of colours with such varieties as C. niveum, insigne Sandere, i. 
Sanderianum and a host of yellow insignes. For a large yellow and white 
form C. X aureum Surprise still holds its own, and is not now an expensive 
variety. Then there are such varieties as C. X aureum Cidippe, x Mrs. 
Wm. Mostyn, X Euryades, and many other richly-coloured things, and for 
elegant flowers C. x Minos Youngii, X vexillarium, X Baron Schréder, X 
Arthurianum, and other Fairrieanum hybrids. C. X Leeanum, too, forms 
a pretty class for those who like intermediate colours, and amongst the 
species C. Charlesworthii and C. Spicerianum make a charming contrast 
when grouped together. 
While the plants are in flower they should be grouped at one end of the
