PrrRIE.— On new Species of Uncinia, 271 
This species of Lepidium is greedily eaten by sheep, and it is only in 
spots to which sheep cannot get ready access that specimens are now to be 
gathered. 
Art. XXX.— Description of three new Species of Carne 
By D. Preme, M.A. 
[Read before the Otago Institute, 12th August, 1884.] 
1. Uneinia laxiflora, n. sp. 
A pENSELY tufted species. 
Culms 14 inches to 2 feet high, slender, trigonous, scabrid towards the top. 
Leaves as long as or rather longer than the culms, very narrow (iz 
inch wide), flat or concave, slightly scabrid, the expanded bases sheathing 
the lower part of the culm. ; 
Spikelet very lax-flowered, slender, 24-84 inches long; bract leafy, 
setose, or none. 
Glumes distant, green, lanceolate, sub-acute, shorter than the utricle. 
Utriele plano-convex, linear oblong, tapering at both ends, with numer- 
ous faint nerves; bristle half the length of the utricle. 
Hab. Owake Flat near Catlin’s River (P. Goyen); Stewart Island; 
Buller Valley (T. F. Cheeseman). 
This species is closely allied to the next U. rigida, mihi. It is also 
allied more remotely to U. filiformis, Boott, and U. cespitosa, Boott. The 
latter as described in the ** Handbook" appears to include several distinct 
forms, of which this is probably one. U. caspitosa, Boott, is there said to be 
very variable, but I do not find it so. I have never gathered specimens of 
it in Otago, or indeed elsewhere than in the North Island. 
2. Uncinia rigida, n. sp. 
A densely tufted species. 
Culms 16-30 inches high, rather stout, terete, slightly scabrid towards 
the top. 
Leaves as long as or rather shorter than the culms, flat or trigonous, 
isis inch broad, strongly keeled, scabrid. 
Spikelets very uniform, 2-21 inches long, rather slender, bract ld 
twice as long as the spikelets. 
Glumes ovate-lanceolate, obtuse or acute, laxly imbricate, brownish, with 
scarious margin 
Utricle slightly longer than the glumes, fusiform, plano-convex, tapering 
at both ends, brownish, with numerous faint nerves, the bristle nearly as 
' long as the utricle.
