To Linnean Society, President and Council   10 May 1869

Report on M^rs Barber’s paper.

M^rs Barber’s paper seems to me worth publishing, because the dependence of the fertilization of a plant on one kind of insects alone, though not an unknown case, is very rare.¹ Nor has any instance been recorded, as far as I can remember, of the access of other insects, being prevented by a mechanical obstacle requiring strength to be overcome. All the figures would of course be desirable and ornamental, but It would quite suffice to give on wood two of the adjoining flowers, one with a bee entering and one without. The outline fig 4 should also be given, as this shews better than fig 1 the contracted tube. It would be well to give the outline fig 3. if anyone can explain to the artist the structure of the fold embracing the base of the pistil, which is not clear to me.²
