endogens

There are plants normally of an intermediate character, while, to take exceptional instances, there are exogens with the leaves and flowers of endogens, and endogens whose outward organisation, at any rate, assimilates them to exogens.

Take the characters of exogens as distinct from endogens; even under ordinary circumstances, no absolute distinction can be drawn between them.

Henslow also suggests that endogens have originated from exogenous plants through self-adaptation to an aquatic habit, [256] which is in line with our idea that certain classes of animals have diverged from the more primitive ones by change of habit, although this has led to the development of new class-characteristics by use and disuse, phenomena which naturally do not operate in plants, owing to their fixed conditions.

Next, omitting an inconspicuous class, represented by but a few parasitical plants incapable of preservation as fossils, come the endogens — monocotyledonous flowering plants, that include the palms, the liliaceæ, and several other families, all characterised by the parallel venation of their leaves.

Since his arrival on Texan ground, he had devoted much attention to the study of the _cactaceae_; and now having reached Mexico, the home of these singular endogens, he might be said to have gone cactus-mad.
