This appears to be a very distinct species, most nearly allied to the L. Alopecunis, Desv., of Tierra del Fuego 

 and the Falkland Islands, a plant which Mr. Kunth considers as a form of L. Peruviana, Desv., and which much 

 resembles the present in size, general appearance, and in all particulars but the segments of the perianth, which are 

 in L. Alopecurus lacerated and fimbriated at the scarious margins, like the braeteola>. It also resembles some states 

 of L. campestris, D. C, as that plant appears in Tasmania, but the leaflets of the perianth are nearly scarious through- 

 out in that species, more plane and not so thick and coriaceous ; the outer ones are also in this very convex and 

 distinctly carinated above the middle.

 latis obtusis teretiusculis compressis fistulosis basi vagioantibus dorso versus medium marginibusque vagi-

Hab. Lord Auckland's group ; exposed places on tlie liills, very abundant, forming large green patches.

 Pedunculitis anni praeteriti elongatus, validus, erectus, folio longior. — Csetera mihi omnino ignota. 



A close examination of this species with the Gaimardia australu (Gaudichaud in Freyc. Voy. Rot. p. 418. t. 30). 

 has satisfied me that they are, as far as I can judge without flowers or fruit, congeneric. The habit of the two 

 plants is entirely the same, and both form extended plane hard green tufts on the bare boggy surface of the hills in 

 their respective islands, often of two or three yards across. The present is rather the smaller species, with much 

 smaller leaves, not flattened on the upper surface, ciliated at the back about the middle, as also on the sides and 

 margins of the sheaths, which are produced upwards into a shorter ligula than in G. australu.
