The following communications were read :— 
Norte oN Pinguicula vulgaris, LINN., and its variants towards 
grandiflora. By Dr. Wm. MacLean. Communicated by 
Professor BAYLEY BALFour, F.R.S. 
While botanising along the coast of Black Isle in June 
1905 I was struck by the unusual size and vivid colour of 
some colonies of Pinguicula. On examining some specimens 
they showed the overlapping segments and bifid spur usually 
associated with P. grandiflora. In the following year 
careful examination showed that the range of distribu- 
tion was fairly wide—I examined along five miles—and 
that the gradations from the ordinary small flowered form 
with the long subulate spur to the large one with richly 
purple corolla and bicornuate spur shaded off into one 
another by fine stages, and between the two extremes, 
one found the gradual differentiation in all stages of size 
of corolla and condition of spur (¢f. similar condition in 
Pyrenees). 
The large form: the scapes are numerous—six to eight 
from a single plant, are over 6 inches in length, corolla 
over 4 inch at greatest, spur not merely notched but 
distinctly bicornuate. Color a rich purple, intensifying 
towards the spur, faintly veined.
