Rare aquatic plants of the Volga delta unclude Aldrovanda veiculosa and Nelumbo caspica.

Caspary [92] mentions a flower of _Aldrovanda vesiculosa_, which was elevated on a stalk that was adherent to the stem for a certain distance, and then separated from it.

Nitschke, Dr., references to his papers on Drosera, 1 --, on sensitiveness of backs of leaves of Drosera, 231 --, on direction of inflected tentacles in Drosera, 244 --, on Aldrovanda, 322

I think so because the marginal spikes of Dionaea apparently represent the extreme marginal tentacles of Drosera, the six (sometimes eight) sensitive filaments on the upper surface, as well as the more numerous ones in Aldrovanda, representing the central [page 361] tentacles of Drosera, with their glands aborted, but their sensitiveness retained.

It would appear that this has actually occurred to a partial extent with the leaves of Aldrovanda; the outer parts of which possess absorbent organs, but no glands fitted for the secretion of any digestive fluid, these being confined to the inner parts.

In Aldrovanda it appears to be the basal parts alone which contract and carry with them the broad, thin margins of the lobes.

* The drawings of Drosera and Dionaea, given in this work, were made for me by my son George Darwin; those of Aldrovanda, and of the several species of Utricularia, by my son Francis.

Drosera, through the same means, together with the movements of the tentacles; by Dionaea and Aldrovanda, through the closing of the blades of the leaf.

Hereafter I shall be excessively glad to read a paper about Aldrovanda

The circumferential part of the leaf of Aldrovanda thus differs greatly from that of Dionaea; nor can the points on the rim be considered as homologous with the spikes round the leaves of Dionaea, as these latter are prolongations of the blade, and not mere epidermic productions.
