AUGUST, 1910.] THE ORCHID REVIEW. 255 
R.H.S. SctENTIFIC COMMITTEE.—The following references to Orchids 
exhibited at meetings of the Scientific Committee are taken from the 
Official Report. They commence from the date of our last notes (O.R., 
Xvil. p. 319) :— 
November gth, 1909 :-— 
MALFORMED OrcuHIDs.—Mr. G. Wilson, F.L.S., showed malformed 
Lycaste Skinneri, Odontoglossum and Cattleyas, upon which Mr. Rolfe, 
A.L.S., who examined them, reported as follows: ‘* The flower of Lycaste 
Skinneri has a free, dark purple filament, 3in. long, opposite to one of the 
side lobes of the lip, and as the latter as lost its colour and become like 
the petals in texture, it is an evident case of replacement. There are 
three flowers of Cattleya labiata, one in which the lip has reverted to a 
simple petal, giving a regular perianth, while the column is straight and has 
an additional perfect anther, showing that one side lobe of the lip has 
been developed as an anther, while the other has been suppressed. In a 
second flower the sepals have become petal-like in shape and colour. In 
the third flower there are two sepals, two petals, and a slender column and 
anther, the lip being being totally suppressed, and the flower dimerous. 
The other is a three-flowered inflorescence of Odontoglossum crispum in 
which the column is abortive in each case, and the lip rather full, though 
otherwise normal.” 
November 23rd, 1909 :— 
CATTLEYA WITH DIPHYLLOUS GROWTH.—Mr. Hawkes, Osterley Park 
‘Gardens, sent a growth of Cattleya Gaskelliana which had produced two 
leaves. This condition, Mr. Rolfe, A.L.S., said, is probably a reversion to 
an ancestral type, and is occasionally seen in other monophyllous Cattleyas. 
December 12th, 1909 :— 
SEEDLING ONcIDIUM.—Mr. Wilson, F.L.S., showed a flower of a 
hybrid Oncidium (O. tigrinum xX O. lamelligerum) raised by Messrs. 
Charlesworth. This is the first recorded seedling of an Oncidium raised in 
this country. . 
January 11th, 1910 :— 
ORCHID HYBRID BETWEEN ALBINOS.—Mr. Thwaites, Streatham Hill, 
showed a flowering plant of Cattleya Gaskelliana alba @ X C. Mendeli: 
alba ¢. The flowers were not pure white, as in the parents (although they 
appeared to be so in the bud), but had a faint and very pleasing pearly-pink 
flush over them. So far, two plants have flowered with the same character ; 
others are in bud. 
February 22nd, 1909 :— . 
MALFORMED CyYPRIPEDIUM.—From boat athicy, P.C., came mal- 
formed specimens of Cypripedium barbatum. One flower showed the
