This plant may be regarded as anatomically the most primitive of the Medulloseae.
Garrod in 1876 and 1877 who finally divested the Family of these aliens, but until examples of some of the other genera have been anatomically examined it may not be safe to say that they all belong to the Pteroptochidae.
A consideration of these facts emphasizes still more fully the view with which we set out, that all living substance is fundamentally, the same, though differentiated both anatomically and physiologically in many directions and in different degrees.
Again, the degree of differentiation is very slight anatomically, but delicate protoplasmic threads have been shown to extend through all cell-walls, connecting together all the protoplasts of a plant.
The foot of the higher apes, though often spoken of as a hand, is anatomically not such, but a prehensile foot.
