The above described plant is very nearly allied both to the Hierocldoe antarctica, Br., and to the II. Magellaniea, Pal. de Beauv., if indeed these three be truly distinct. When describing the first of them, Mr. Brown remarks, " huic quam maxime affinis est Holcus redolens, Forst :" and he draws the chief distinction from the inner glume of the latter being three-nerved and the cilia? on the margin of its lower florets being curved. In the Tasmanian specimens of H. antarctica, which I have examined, I find that the upper glume is often furnished with two short lateral nerves at the base, and in the New Zealand species (H. redolens) the cilia? alluded to are as often straight as curved. Perhaps a more constant character between the plants of these two countries exists in the surface of the leaves of the //. antarctica being decidedly scabrid, not only to the touch but under a moderate magnifying power, its florets also are not so abruptly truncated ; I have not been able to detect any other points of difference.
