The spikelets of this and the following species present very different appearances owing to the character and arrangement of the utricles. In the above species the ripe utricles are closely packed tending to spread at a greater angle from the rachis than in the following species. This difference in arrangement is shown in the relative density of scars on the rachis, typical examples of which are illustrated on the accompanying plates.

As Forster's publication of Solander's manuscript name, C. ternaria, was without a description, the first valid publication of this name is in Hooker's Flora Antarctica which is predated by Schkuhr's C. geminata in “Beschreibung und Abbildungen der Riedgrasern.” The latter, therefore, must stand as the valid name.

C. ternaria var. minor Boott (Ill. Car. iv (1867) t. 597 right-hand side of plate) as emended by Kukenthal (loc. cit.) is a depauperated state of C. geminata although in certain areas where ecological conditions are unfavourable it may be the prevailing form. This appears to be the case in Fiordland.
