arboraceous

I learned, too, to cultivate an acquaintance with some two or three species of doris, that carry their arboraceous, tree-like lungs on their backs, as Macduff's soldiers carried the boughs of Birnam wood to the Hill of Dunsinane; and I soon acquired a sort of affection for certain shells, which bore, as I supposed, a more exotic aspect than their neighbours.

Amid forests of arboraceous ferns, and of horse-tails tall as the masts of pinnaces, there stood up gigantic club-mosses, thicker than the body of a man, and from sixty to eighty feet in height, that mingled their foliage with strange monsters of the vegetable world, of types no longer recognisable among the existing forms—sculptured ullodendra, bearing rectilinear stripes of sessile cones along their sides—and ornately tatooed sigillaria, fluted like columns, and with vertical rows of leaves bristling over their stems and larger branches.

This tends to show, at least, that if but one-half the fires that have occurred had been kindled, the arboraceous growth could have withstood their destructive influences, and the whole surface of what is now prairie would be forest.

And then, far from its original bed in the rock, amid the jerkings of a cockling sea, the mass breaks through the supporting float, and settles far beneath, amid the green and silent twilight of the bottom, where its mosses and lichens yield their place to stony encrustations of deep purple, and to miniature thickets of arboraceous zoöphites.

We were in the middle of a broad and now sluggish river the banks of which were lined by giant, arboraceous ferns, raising their mighty fronds fifty, one hundred, two hundred feet into the quiet air.
