ApRIL, 1909-] THE ORCHID REVIEW. $a 
Dendrobium nobile murrhiniacum crossed with D. n. Ballianum gave seed- 
lings almost exactly like typical D. nobile. D. n. virginale, which when 
selfed gives quite white seedlings, when crossed with D. Findlayanum 
_ gives D. X Cybele, all the seedlings being.alike, and no light forms being 
among them. Similarly, Dendrobium Wardianum album crossed with D. 
nobile album gives all coloured flowers. Such “ reversions” to coloured 
forms are becoming very common. 
February 23rd, 1909 :-— 
MALFORMATIONS IN ORCHIDS.—Mr. Gurney Wilson, F.L.S., sent the 
apical portion of a pseudobulb of Dendrobium nobile bearing a shoot from 
which roots had grown as in a vegetative shoot, and a flower, the lateral 
petals of which were coloured like the labellum. He also sent a dimerous 
flower of D. nobile, with the lip suppressed and the two lateral sepals 
coherent. A Cypripedium from Sir Jeremiah Colman having two dorsal 
sepals was also shown. 
MENDELISM IN ORCHIDS.—Mr. R. A. Rolfe showed flowers the result of 
crossing Epidendrum evectum and E, xanthinum. The former of these is 
purplish in colour, the latter yellow. The first cross gives E. x kewense, 
and flowers of this were shown. Seedlings had been raised from E. X 
kewense after self-fertilisation, and of these, one which flowered earlier was 
practically a reproduction: of E. X kewense, while of two others (flowers of 
which were shown) one showed partial reversion toward the purple E. 
evectum, the other toward the yellow E. xanthinum. He also showed the 
result of recrossing E. X kewense with the original parent, E. evectum, the 
resulting plant having a purple flower not quite so dark as the latter parent, 
and said that E. x kewense re-crossed with E. xanthinum gave a more 
yellow flower than E. X kewense. Other plants of the crosses were yet to 
flower. 
March oth, 1909 :— 
BEETLE IN STEM OF VANDA TERES.—Mr. G. S. Saunders reported that . 
he had examined the stem of Vanda teres sent to a recent meeting of the 
Committee, and found that the beetle boring into it was a species of 
Xyleborus, not a native, mor, so far as can be ascertained, recorded as 
occurring in Europe up to this time. The plants attacked were sent by 
Mr. Rogers from a greenhouse at Bury, Lancs. 
ABERRANT ORCHID.—From Mr. G. W. Miller, of Wisbech, came a 
specimen of Cypripedium Pitcherianum, Williams’ var., with a _ well- 
formed double lip. 
OrcuHip Hysrips.—Mr. H. J. Chapman showed Odontioda Bradshawie,
