SEPTEMBER, Ig11.} THE ORCHID REVIEW. 287 
sepals (antero-posterior), the anterior one being very large, owing to fusion 
of the two normal lateral ones; two lateral petals larger than normal, 
doubtless correlated with the complete absence of the labellum. The 
absence of the latter must be attributed either to abortion or to congenital 
and intimate fusion with the column (an analogy for such a fusion exists in 
the third flower, and the column has its lateral petaloid appendages larger 
than usual). The ovary appears to be normal. A very interesting fact is 
that the bracts subtending, two or three of the flowers showing positive 
dedoublement, are double, having two tips and two midribs. In such cases 
the splitting tendency is very powerful, and if it went further would result 
in the formation of two flowers side by side; these then might become 
spatially separated in a vertical direction on the axis of the spike. The 
structure of the dimorous flower has probably, from a morphological point 
of view, nothing whatever to do with the other malformations, but, 
physiologically, there may be a connection. Exigencies of nutrition may 
demand that, if some flowers have an extra number of organs to be fed, 
other flowers must not be supplied with so many organs, economy in the 
spike-household being thus maintained.”

CATASETUM CLIFTONII.—Mr. James O’Brien showed plants under this 
name from the collections of Sir Trevor Lawrence Bart., and Sir Jeremiah 
Colman, Bart., respectively. The flowers presented several minor points of 
‘difference in coloration and in the form of the lip, but both had a large callus 
upon the latter. No essential difference was to be seen in habit. Mr. 
‘O’Brien considered them to be forms of one species, a view with which Dr. 
Rendle, to whom they were referred, concurred. Dr. Rendle regarded them 
as forms of the very variable Catasetum Bungerothii, a Venezuelan species 
figured in Bot. Mag., tab. 6998. 
MALFORMED CATTLEYA.—Mr. O’Brien also showed a malformed 
Cattleya labiata, upon which Dr. Rendle commented as follows: ‘‘ The. 
dorsal sepal has become broad and short, resembling more the lip and 
petals ; the lateral petals have become shorter, resembling the lip in colour, 
but slightly smaller; they are enclosed by the lip and convolute with each 
other; the dorsal sepal, with lip and petals, formed a central rosette; the 
lateral petals are shorter than usual, but otherwise normal. The column 
is reduced, forming a pillar-like structure bearing an aborted anther.” 
July 18th, 1911: BOTANICAL CERTIFICATES.—Catasetum reflexum, a 
mew species, from Peru, approaching Cycnoches in some of its characters, 
was sent from Glasnevin by Sir Fred. Moore. On the motion of Mr. 
O’Brien, seconded by Mr. Wilson, a Botanical Certificate was unanimously 
xecommended to this plant. A new Dendrobium, from Java, was exhibited 
by Sir Trevor Lawrence, Bart. It had been described under the name of
