Campbell's Islands.] Some of the New Zealand species are wonderful features in the forest scenery of those islands; they form huge tufted masses, often as large as the human body, perched on the naked limbs of the most lofty pines; elevated as they are 80-100 feet above the ground, they remind the beholder of the nest of some gigantic bird.

This curious little species is allied to none with which I am acquainted; in size and general appearance it somewhat resembles the Luzula arcuata, Hook., of the Scottish Alps. The form of the leaves is that of Juncus castaneus, Sm., but they are in this plant solid internally and of quite a different structure. The capitate flowers and naked scapes are common to this, with the J. biglumis, L., J. triglumis, L., and with the following.
