are larger, and in every other respect much finer, than that in the Bot. Mag. ; hut 
considering that the properties of the flowers have been known to vary as the 
treatment has been good or bad. or the season of flowering favourable or unfavourable, 
we feel inclined to consider the greater size and beauty of the flower here shown 
as most probably attributable to these causes. As an instance, in the British Flower 
Garden, page 348, we find the flowers there represented to differ from those in the 
Bot. Mag. both in size and shad eof colouring, which is accounted for by the 
plants flowering at different seasons. Whether the view here taken be correct or 
not, our present experience does not enable us to say ; but if so much depends on 
culture, how necessary it is that the best method should be properly made known, 
and carefully practised ! 
For want of the necessary information, we are obliged to defer our remarks on 
culture, &c. to the succeeding number, when we shall take pains to point out 
that system of management which experience has proved to be advantageous to the 
growth of this splendid plant. Plants or seeds may be obtained of any of the 
London and most of the country nurserymen. 
The generic name is explained in Vol. III., page 266. 
The specific name is given by Mr. Nuttall, on account of the magnitude, and 
sort of general resemblance of the flowers to those of Cohcea scandens.
