The female plant of this species so entirely resembles the L. simplex, Forst., of New Zealand, that it has been 
referred to that species by Brown, and, following him, by myself in the ‘ Flora Nove-Zelandiee,” At the period of 
publication of the latter work, I had not discovered that the plant I now consider to be the female of the Tasmanian 
L. Brownii (and which is very different from the female New Zealand L. simplex) was so, both because of its great 
dissimilarity, and because of its bearing a different number in Gunn's collection. 1 have however been confirmed 
in this conclusion by Dr. Mueller sending the same plants as sexes of one from Victoria, under Brown's name of 
L. simplex.—Culms 1-2 feet high, slender. Male panicle effuse, of six to twenty amenta, on pubescent, flexuous 
pedicels, each cylindrical, ovate, or lanceolate, about 4-3 inch long, of numerous, shining, deep-brown, ovate, mu- 
cronate or acuminate, glabrous scales. Female amenta very short, densely fascicled, tbeir scales similar to those of 
the males. Perianth of the male flower of four or five unequal, irregular, linear glumes; of the female of six broadly 
ovate-oblong, acuminate glumes, the inner very much shorter.—PLate CXXXVI. Fig. 1, male flower; 2, female 
ditto; 3, the same, laid open :—all magnified. 
2. Leptocarpus tenax (Br. Prodr. 250) ; culmis simplicibus teretibus, vaginis appressis, panicule 
ramis albo-tomentosis, (maseulis ? culmis gracilibus cinereis, amentis parvis ovoideis laxe paniculatis, squa- 
mis obtusis, perianthiis 4-glumis,) femineis culmis robustis, amentis majusculis in spicam divisam erectam

But for Dr. Mueller's having doubtfully suggested the males and females of this plant as belonging to one 
species, I should not have suspected such to be the case, though analogy with Z. Brownii, and the fact of both 
forms being common in Tasmania, and each being unisexual, render his suggestion almost a certainty. The male 
plant very strongly resembles Restio mierostachys, Br., from South-west Australia, if it be not that plant.—A larger, 
stouter plant than Z. simplex. Sheaths with deciduous, membranous apices. Male with slender culms, 2-5 feet 
high, and a very copious-flowered panicle of very small, ovoid amenta, each about 2-2 inch long, their scales broad, 
acute or blunt, and mucronate. Perianth of four linear-oblong glumes. Female culms less slender. Amenta con- 
gested in alternate, almost sessile fascicles, their scales very hard, cartilaginous, broadly ovate, with short, rigid, 
patent, subulate apices, very much larger than the male scales, their margins membranous. Perianth with long, 
narrow glumes, the outer larger. 
I have examined an unnamed specimen of the male plant of this, gathered in Recherche Bay by Labillardiere, 
who nevertheless took the male of the South-west Australian Zyginia imberbis, Br., for that of his Tasmanian 
S. tenax, as pointed out by Brown.
