Var. 8, Massacre Day, Zyall. Nat. name, “Oioi” (shaking), Col. 
A variable plant in size; abundant in Tasmania. Stems quite simple, numerous, arising from a sheathed 
creeping rhizome, slender or stout, 1-2 fect-high. Sheaths 1-3 inches apart, 3 inch long. Peduncles of the male 
spikes glabrous or downy. Zuscicles of female flowers solitary or generally crowded into lobed heads 3-1 inch long, 
which are sessile and alternate on the culms, sometimes very few, small, and distant. Outer scales broadly 
ovate, acuminate or mucronate or awned, longer than the glumes, which are lanceolate, the outer acuminate. The 
var. B is a much larger and more robust plant than Z. simple, with fascicles of flowers collected in dense somewhat 
panicled sessile heads nearly an inch long. I had long supposed the males and females of this plant to belong to 
different species, especially as Mr. Brown describes the female flowers of R. simplex as occurring on the upper part 
of the same culm as the males: this however is not the case with Forster's original specimen from New Zealand, nor 
with mine from Tasmania. Those from the latter country are shorter and more slender than the New Zealand ones, 
with terminal heads or fascicles of spikelets, and the peduncles of the female spikelets more downy. I can find no 
characters however whereby to separate them specifically.—Prate LXI. 4. Female plants of Z. simplex, its

Rigid, wiry, green plants, with very slender, often flexuose, fastigiately branched, striate culms, flattened on one 
side. Sheuths short, very coriaceous, with generally bearded mouths, and short, subulate, often spreading points. 
Spikes unisexual, short, rigid, subulate, sunk in the sheaths, few-flowered. Males with three or four flowers each, 
hid within a hard convolute scale. Glwmes six, lanceolate. Stamens three; anthers peltate, one-celled, exserted. 
Female spike of two or three flowers, the terminal only fertile. Scales as in the male, but more numerous. Glumes 
six, short and broad. Nut terminal on the spike, bony, obovate, blunt, shining, one-celled and seeded, with two or 
three curling deciduous styles, longer than the six persistent glumes which surround its base.—This genus is also 
found in Tasmania and Australia, as are two of the New Zealand species. Mr. Brown, who had not seen the fruit 
(which is however correctly represented in Labillardiére’s drawing), united it with Restio, from which it differs in 
the one-celled and seeded nut; it is much more nearly allied to Hypolena, but differs conspicuously in habit and
