88 FLORA OF TASMANIA. [ Cyperacee. 
Very dissimilar to the other Tasmanian species, being robust, rigid, 2-3 feet high, and bearing a very dense 
globose capitulum the size of a marble. Culms compressed, rigid, leafless, sheathed at the base, with a pungent 
apex. Spikelets extremely numerous and very densely packed, of six to eight broad, concave, blunt, striated, pale- 
brown scales. Stamens and stigmas three. 
T, Isolepis setacea (Br. Prodr. 222); pusilla, culmis setaceis striatis basi monophyllis, spiculis 
1-3 ovatis lateralibus v. terminalibus, squamis acutis carinatis 2-3-andris, nuce globosa, longitudinaliter 
sulcata, stigmatibus 2-3.—Kuntk, En. 193. I. margaritifera, Nees, in Ann. and Mag. Nat. Hist. vi. 46. 
(Gunn, 421, 976.) 
Has. Probably common in marshy places, but I have seen no specimens but those from Penquite, 
Gunn.—(Fl. Nov.) 
Disrris. Extratropical Australia, South Africa, India, temperate and warm Europe and Asia. 
Culms capillary, two or four inches high. Leaves short, very slender. Spikelets short, one to three, some- 
, times, especially when solitary, almost terminal. Scales six or eight, acute, keeled, and striate. Nut globose, 
deeply grooved, whitish or brown. 
8. Isolepis Saviana (Schult. Mant. ii. 63); culmis setaceis subcapillaribusve basi monophyllis, 
spiculis 1-3 ovatis, squamis 3-andris obtusis carinatis sulcato-nervosis, nuce late obovata compressa obtuse 
trigona alba v. pallide fusca creberrime punctata (asperula).—XKunth, En. ii. 193. Scirpus Savii, Spr. Syst. 
Veg. i. 201 ; Eng. Bot. Suppl. t. 2782. (Gunn, 421.) 
Has. Abundant in moist, sandy, and marshy places.—(Fl. all summer.) (v. v.) 
DisrRrB. Extratropical Australia, Europe, Canary Islands, and North Africa. (A native of England.) 
My specimens agree perfectly with European ones. Very similar to I. setacea, being pale-green, and having, 
like it, often but one almost terminal spikelet ; also most nearly allied to 1. pygmea, but that has a smaller, trique- 
trous, more minutely punctulate nut.—Cu/ms 1-3 inches high, very slender, with one leaf at the base.  Spikelets 
one to three, small, 4—j inch long, of six to eight ovate, blunt, concave, bluntly keeled, deeply striate or grooved 
scales. Nut compressed, obovate, obtusely three-angled, white or grey-brown, deeply punctate so as to look rough, 
its surface glistening and iridescent. 
9. Isolepis cartilaginea (Br. Prodr. 222) ; culmis basi foliatis dense czespitosis foliisque crassius- 
culis rigidis erectis, spiculis 3-6 (rarius solitariis) lateralibus seepe involucratis, squamis 3-andris navicula- 
ribus profunde carinatis lateribus impressis sulcato-nervosis inferioribus mucronatis, nuce elliptica v. ob- 
longa obtuse trigona punctulata.—F/. N, Zeal. i. 271; Nees im Plant. Preiss. ii. 13.

Var. a; culmis rigidiusculis 1-4-pollicaribus, spiculis 4-6, squamarum lateribus purpureis. (Gunn, 
582. (Tas. CXLV. A.) 
Var. 8; culmis rigidiusculis 1—4-pollicaribus, spiculis 2-3, sguamis pallide viridibus. 
Var. y; culmis gracilibus subsetaceis, spiculis 1-3, squamis pallidis. (Gunn, 421?) (Tas. CXLV.

Disrris. Extratropical Australia, New Zealand, and South Africa. 
A very well marked species in its common form of a short, ri 
with several lateral, often involucrate spikelets of deeply keeled, shining, navicular, suleate scales, and with a pale- 
brown, elliptic-oblong, bluntly trigonous, not compressed, minutely punctulate nut; but the culms are sometimes 
slender and setaceous, like those of I. Saviana and setacea ; the scales, though constant in general characters, are 
often wholly yellow-green ; the spikelets are sometimes solitary, and have no involucre-like elongated scale at the 
the varieties apparently growing intermixed.— (Fl. Oct.-
