282 BOTANICAL SOCIETY OF EDINBURGH.  [Szss. uxx1, 
MEETING OF THE SOCIETY, 
June 13, 1907. 
J. Ruraerrorp Hint, Esq., President, in the Chair. 
The following communications were read :— 
Nore ON Errect or Frost ON ConireRS. By Dr. 
A. W. BorTHwIck. 
Dr. BortHwick exhibited specimens of Silver Fir and 
Spruce, the terminal buds of which had been killed by frost, 
and this had resulted in the production of a rosette of new 
buds at the base of the one destroyed. In some of the 
specimens these rosette buds had grown out into shoots, 
producing a very characteristic appearance typical of this 
kind of damage. 
NOTE ON OPHRYS HYBRIDA, Pokorny. By Mr. 
J. F. JEFFREY. 
Ophrys hybrida, Pokorny = 0. aranifera, Huds. x O. musei- 
era, Huds. 
A fresh specimen of this supposed natural hybrid between 
the Spider and the Fly Orchids was sent to me at the end of 
May from the chalk downs at Wye, Kent, where it was first 
recorded for Britain in 1905. Ophrys aranifera and O. 
muscifera both oceur freely in the vicinity, but the hybrid 
appears to be very scarce. 
This interesting plant has long been known in Europe, see 
“ Reichb. fil. Ic. Fl. Germ.,” xiii., xiv., p. 79, t. 465, f. 1, where it 
is stated to have been found growing with the two species 
named, near Vienna, in 1846. See also Rolfe, in “Orchid 
Review,” xiil. (1905), pp. 233-235, with fig., and Rendle in 
“ Journ. Bot.,’ 1906, pp. 347-349. 
The specimen, together with an example of both parents, 
is preserved in the Museum of the Royal Botanic Garden, 
Edinburgh.
