Any one who will consider this list will see that the young plants selected for observation, fairly represent the whole vegetable series excepting the lowest cryptogams, and the movements of some of the latter when mature will hereafter be described.

Dicotyledons and amongst Monocotyledons, together with several Cryptogams, have now been described.

As in cryptogams, the ferns of Earth, two forms are alternating mature phases of a complex life cycle.

The gray-brown surface was already covered with miniature black stacks of cryptogams, the dry microscopic plants that held the desert soil together.

When I come back from it I shall publish such papers on the cryptogams of Kamschatka that no one will ever set the mark of intelligence upon my head again.

He had dealt with the coleoptera and he was deep in the vascular cryptogams before the frigate turned her head north at last.

It reproduced like the vegetable cryptogams, especially the Pteridophyta, having spore cases at the tips of the wings and evidently developing from a thallus or prothallus.

But by far the most important point in the list, is that we meet with sleeping plants in 28 families, in all the great divisions of the Phanerogamic series, and in one Cryptogam.

We were just having a little chat about the higher cryptogams, that's all.

Jack was taken up with sailing his ship and Stephen, quite apart from the preservation, classification and description of his Tristan da Cunha specimens, the rich harvest of extreme activity in a cruelly limited time on the lower parts of that scientifically unknown island, inhabited by numbers of nondescript cryptogams, probably several flowering plants (though this was the wrong season for them), a quantity of beetles and other insects, some spiders, and at least two peculiar birds, a finch and a thrush, and quite apart from his Malay, had his sick-berth to look after.
