NEW ZEALAND FLORA. 389 
naked, erect culms, and sessile flowers. At present it has only 
been cbserved in the Broken River basin, Southern Alps, alt. 
2000ft. 
Centrolepis monogyna, Benth.—(Alepyrum monogynum, Hook, f.)— 
This moss-like plant occurs in swampy places at an elevation of 
3000ft. in Arthur’s Pass, where it was observed by the writer in 
1877, when specimens were distributed under the M.S. name of 
Alepyrum viride. 
It forms large patches scarcely Win. in height when in flower. 
Leaves deep green, subulate, acute, dilated into a broad mem- 
branous base, with a few short hairs at the back. Bracts sub- 
opposite, narrow. Flowers two, eachinvested by a semitrans- 
parent scale, which nearly equals the bract, and consisting ofa 
single stamen and a single carpel. 
Hievochle alpina, Roem. and Schultes, var. submutica—(H. sub- 
mutica, F. Mueller, Danthonia buchanani, J. Buchanan, “Man. of 
Indig. Grasses of N.Z., p. 87, pl. xxxv., not of Hook, f.) This 
form is intermediate between H. vedolens and H. alpina, but is most 
closely related to the latter. The New Zealand plant agrees 
with that of Victoria in habit, and especially in the lower glumes 
being scarcely ciliated, but the awns are usually longer. The 
panicle is more open than in H. alpina ; the branches are longer, 
and extremely slender, distant, usually drooping ; spikelets 3-6; 
leaves broad, flat. Common in mountain districts, especially on 
the West Coast of the South Island. 
In “ Flora Australiensis” Mr. Bentham unites AH. vedolens and 
H, alpina, and considers our plant a connecting form which may 
possibly prove worthy of specific rank. I fully agree with Mr. 
Buchanan in considering H. alpina distinct from the European 
H, borealis ; but cannot understand his having mistaken our plant 
for a Danthonia, especially for D. buchanant, which, independently 
of its generic and sectional distinctive characters, is described as 
having a short contracted panicle and filiform leaves. 
Stipa micrantha, R. Br.—(Streptachne vamosissima, Trin. and Rup.) 
—TI have previously recorded the occurrence of this plant in the 
Colony, and now add that it was originally discovered by Mr. 
W. T. L. Travers, near Fox. Hill, in the Nelson district. Re- 
cently it has been found in great abundance in the Takaka 
Ranges, Nelson, by the Rev. F. D. Spencer, who informs me 
that its culms attain several feet in length. 
It occurs in small quantity on the Miramar peninsula, near 
Wellington, and must be regarded as a relic of the indigenous 
vegetation of that locality, although I formeriy considered it to 
be naturalised ony. The culms are from 2 to 5 feet long, sub- 
erect or prostrate, much branched ; the branches sometimes ab- 
breviated, and forming rounded bunches at the nodes, sometimes 
long and spreading. Panicle from 6” to 2’ in length; branches 
numerous, capillary ; spikelets small; outer glumes narrow, 
nearly equal. Flowering glume shortly stipitate, entire ; awn, 
¥,” long, articulated on the glume. Palea less than half as long
