Campbell's Islands.] FLORA ANTARCTICA. 79 



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.

 brunnea; funiculi incrassati, reliquiis filamentosis membranae externa; seminis circumdati : testa membranacea, 

 pallide flavo-brunnea, obsolete striata v. reticulata. 



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., /. triglumis, L., and with the following.

2. Juncus scheuchzerioides, Gaud.; culmo brevissimo compresso basi fastigiatim ramoso, foliis
