The most important of the larger species are woodwardia, aspidium, asplenium, and, above all, the common pteris.
Many fine ferns dwell here also, especially the beautiful and interesting rock-ferns -- pellaea, and cheilanthes of several species -- fringing and rosetting dry rock-piles and ledges; woodwardia and asplenium on damp spots with fronds six or seven feet high; the delicate maiden-hair in mossy nooks by the falls, and the sturdy, broad-shouldered pteris covering nearly all the dry ground beneath the oaks and pines.
The grass only grows sparsely in tufts above this place, and though vegetation exists up to a height of 10,000 feet on this side, it consists, for the most part, of grey lichens, a little withered grass, and a hardy asplenium.
Nowhere, in the temperate zone, have I seen such an abundance of the pteris, blechnum, and asplenium; yet none of these plants have the stateliness of the arborescent ferns which, at the height of five or six hundred toises, form the principal ornament of equinoctial America.
