and C. De Cockianum, and in neither case is there anything to show 
whether species or hybrids are intended. These might have been omitted, 
and in any case C. bulbosum should not have been included, as it is only 
a synonym of Calypso borealis. These are very slight defects, but might 
have been avoided had some expert spent a few minutes in glancing through 
the list. It is a very compact little book, interleaved throughout for 
additions, and handsomely bound in Russian leather. 
Mr. Measures does not wish to make any profit from the sale of the 
book, but is desirous of benefiting two very worthy institutions. He is 
therefore adding two shillings per copy to the cost price, one shilling of 
which will go to the Gardener's Benevolent Institution and one to the 
Gardener’s Orphan Fund, and if the edition is sold out both will reap a 
substantial benefit. The price is 3s. 6d. per copy, or 3s. 8d. if sent by post. 
CATASETUM x SPLENDENS. 
Three forms of this interesting natural hybrid have flowered with Messrs. 
B. S. Williams and Son, Victoria and Paradise Nurseries, Upper Holloway, 
none of them quite identical with those previously recorded. The first has 
the size and shape of C. x s. viride, the lip being expanded, one and three- 
quarter inches broad, and with a well-developed crest. The colour is light 
yellow throughout, and thus it marks the transition to C. x s. auratiacum. 
A second approaches C. x s. flavescens, the mouth of the lip being one and 
one-eighth inches broad and the sides nearly paraliel, except at the some- 
what reflexed minutely denticulate margin, and the crest well developed. 
The colour is almost that of the preceding, but the sepals and petals slightly 
greener with many minute brown dots, and the lip a little deeper yellow 
with a trace of green within the sac. The third has the lip almost of C. x 
s. O’Brieniana, or a sort of enlarged and somewhat expanded C. macro- 
carpum, but the crest quite obsolete, and the colour ivory-white, very faintly 
tinged with pale green, the sac deep yellow at the base, and a number of 
minute purple dots on the disc of the petals. This form is remarkable for 
combining the colour of C. Bungerothii with a near approach to the shape 
of C. macrocarpum. They are very interesting and beautiful and help 
to confirm the results previously arrived at. The amount of variation is 
remarkable, and is no doubt partly accounted for by the great dissimilarity 
of the two parent species.

I observe in the pages of a Belgian contemporary an attack upon Mr. 
Rolfe respecting his article on Catasetum x splendens, in which he is 
accused of dogmatic assurance, and a pretence to infallibility. It is also
