ground and cinnamon-brown blotches. Its number appears ‘not to be indicated in the 
Catalogue. 
In the 1893 Catalogue occur :— 
“QO. Alexandre,” p. to, ‘n. 179, t. 2, fig. —A form very near to O. x secon 
sulphureum or O. X W. elegans, itt ae -coloured ‘flowers and one or two brow 
spots on the sepals. 
“QO, Alexandre,” p. Io, n. hes t. 5, fig. 177.—A small O. X Wilckeanum with light 
yellow Roweks and cinnamon spot 
“O. X bickleyense,” p. 11, n. oy, t. 6, fig. 58.—See O. Alexandre bickleyense, above. 
It is highly probable that some of the so-called varieties of O. crispum (or 
Alexandre) in other collections are really forms of the present hybrid, as I 
have found them so labelled on several occasions. Errors of this kind 
should be rectified as soon as discovered, as no hybrid can possibly be 
considered as a variety of either parent. 
Considering the present hybrid as a whole, it is remarkable what a wide 
range of variation it presents. Just as in the case of O. x glorioso-crispum, 
there appears to be almost every possible combination of the characters of 
the two parent species. The robust habit, branched inflorescence, and more 
elongated segments of O. luteopurpureum may be combined with the white 
ground of O. crispum, and with the heavy spotting of the former, or almost 
without spots, as in so many forms of the latter. Or the compact habit of 
O. crispum may be coupled with.the yellow colour and brown blotches of 
the other parent, while all kinds of intermediate forms occur, both in shape 
and colour. It is now quite certain that this hybrid is more By morphic 
and polychromic than is generally supposed. 
The following is a list of its various forms, with references to published 
descriptions and figures. It is pretty extensive, but we dare not hope it is 
complete :—
