These transformations have been attributed by some authors to simple bud-variation; but considering the wide

This unusual condition of the male and female reproductive elements in C. adami has been used by Prof. Caspary as an argument against this plant being considered as an ordinary hybrid produced from seed; but we should remember that with hybrids the ovules have not been examined nearly so frequently as the pollen, and they may be much oftener imperfect than is generally supposed.

Nevertheless, in Aceras a single pollinium is sometimes removed by insects, though more rarely than with the other species of Orchis. Aceras (Orchis) longibracteata. Mr. Moggridge has given an interesting account, together with a figure, of this plant which grows in the South of France. The pollinia are attached to a single viscid disc. When they are removed they do not diverge as in O. pyramidalis, but converge and then

constructed so as to be regularly cross-fertilised, it may be asked will it ever revert to its former state; and if it does not so revert, will it become extinct? These questions cannot be answered, any more than in the case of those plants which are now propagated exclusively by buds, stolons, c., but which produce flowers that rarely or never set any seed; and there is reason to believe that a sexual propagation is closely analogous to long-continued self-fertilisation. Finally Mr. Moggridge

We may believe that such reversion is possible, when we hear from Mr. Moggridge that Ophrys scolopa fertilises itself freely in one district of Southern France without the aid of insects, and [page] 29
