H ab. N o rth e rn and Middle Islands, common. B a n k s a n d Solander, ete. (A native of En g lan d .)
A small, slender, excessively variable plant, vaiydng in every locality and habitat, 3 -1 0 inches long, native oi
Europe, jVustraha, and probably other parts of the world. Culms tufted, erect, filiform or capillary, striated, with
one or two leaves at the base. Spikelets solitary, sometimes two to six, small, of six to eight broad, concave, blunt
or mucronate or sharp, pale reddish or chesnut-hrown scales. Stamens one to three. N u t covei'ed with minute
impressed dots, pale, yellow or brownish, compressed, lenticular, or more or less trigonous.—None of my New Zealand
specimens quite agree with the 1. acicularis or Savii of Europe, nor with any of the five or six allied species
in Mr. Brown’s ‘ Prodromus;’ at the same time I find so gi*eat variation in size and habit, the form of the scales,
number of the stamens and styles, and amount of compression of the lenticular or trigonous nut, tbat I am quite at
a loss how to divide my specimens into well-marked varieties. Some of these approach I . Aueklandica of x\uckland’s
Group (FL -Antarct. p. 88. t. 50), but that species has longer, broader leaves, and a much larger and not punctate
nut,—In moist places the heads become proliferous, when it is chiefly distinguished by its smaller size from I.
proliféra.
3. Isolepis cartilaginea, Br. ; pusilla, rigida, culmis brevibus curvis basi 1 - 2-foliatis, foliis trigono-
setaceis basi membranaceis, spiculis 1—3 infra apicem culmi, squamis paucis cartilagineis carinatis striatis

H ab. N o rth e rn Islan d . E a s t Coast, Ahuriri, Colenso.
A small, densely tufted, stout, rigid species, inch high. Culms trigonous, curved. Leaves rigid, subulate,
channelled, keeled. Spikelets one or two, sessile, small, green. Scales coriaceous, rigid, rather distant, curved, much
laterally compressed, subacute, with a thick blunt keel, deeply striate, ivith chesnut-browu lines. Stamens two.
Styles three. N u t broad, triangular, rough, with pitted facets.—I am not convinced of this being Mr. Brown’s
New Holland plant, which has triandrous flowers (a character of little importance, however), and scaberulous nuts,
whereas these can be considered rough from the depth and number of tbe impressed dots only.
4. Isolepis p roliféra, B r. ; culmo te re ti striato stolonifero aphyllo basi vaginato, capitulis polystachyis
passim proliferis lateralibus termiualibusque, spiculis oblongis, squamis ccarinatis obtusis monaudris, stylo
trifido, nucibus obovatis ^apiculatis compressis p u n ctato -striatis pallidis.— B r . Brodr.
IL yb. N o rth e rn Islan d ; watery places. E a s t Coast, etc.,
Rather a large tufted species. Culms 4 -1 0 inches long, thick but weak, striated, terete, leafless, sheathed at
the base. Spikelets short, ovate, brown, clustered at or near the end of the cuhu, proliferous. Scales red-brown,
blunt, herbaceous, not keeled. Stamen one. Style bifid. Nu t obovate, apiculate, compressed, striated with impressed
dots, pale.— Probably a very variable plant, found in many pai'ts of the world.
