it, as he does not refer to the variety in his " Students' Flora 

 of New Zealand." It differs from E. jtmceum in a number of 

 characters that are constant throughout a range extending 

 over more than half the colony. These characters are the 

 simple stout glabrescent tall stems, the large ovate- or linear- 

 lanceolate membranous glabrescent strongly nerved leaves, and 

 the much-branched leafy inflorescence with shortly pedicelled 

 capsules. The spacing of the leaves on the stems is remark- 

 ably uniform and elegant. Only E. 'pallidifloritm, Solander, 

 and E. chionanthum, Haussk., approach it in height and 

 robustness. It is not a hybrid between these species or any 

 others. In the marshes of the Waikato it is a most abundant 

 plant, and imparts to them a distinct facies that is easily 

 recognised from the windows of railway-carriages. 



2. Note on Bhrharta thomsoni, Petrie. 



I can now record the occurrence of this grass in the 

 Auckland Islands, having recently found a number of short 

 flowerless stems in a tuft of Poa gathered there by Mr. F. E. 

 Chapman in January, 1890. The foliage of the species is so 

 characteristic that I have no doubt of the accuracy of this 

 determination. In Mr. Cheeseman's herbarium I have also 

 seen similar flowerless specimens from the mountains in the 

 neighbourhood of Westport, where they were collected by Mr. 

 Townson. The species thus proves to have quite an exten- 

 sive range. 



3. Note on Danthonia australis, Buchanan. 



This species extends to Campbell Island, as is proved 

 by a specimen given me, a good many years ago, by Mr. 

 Buchanan, under the name "Danthonia raoulii, Hook, f." 

 The specimen is quite distinct from the latter species, and is 

 doubtless part of a young tuft of D. australis. The stem is 

 short and unbranched, but in all other respects the grass 

 matches typical specimens from the mountains of the Nelson 

 District. The occurrence of these grasses on the southern off 

 islands establishes further links in the close botanical connec- 

 tion between them and the main islands of New Zealand. 



4, Poa seticulmis, sp. nov. 

 Tufted or spreading, branched below, slender, smooth, 

 pale-green or yellowish, 4 in. -10 in. high. Leaves shorter 

 than the culms, very slender or filiform, erect, striate, smooth, 

 involute. Sheaths broad, membranous, striate, and grooved ; 

 contracted just below the short broad ligule. Culms erect, 

 slender, often filiform, perfectly smooth, clothed almost to 

 the top by the sheaths of the cauline leaves. Panicle ovate, 

 1-J in. -3 in. long ; the branches in pairs, ascending or
