Campbell's Islands.] FLORA ANTARCTICA. 37 



both the present and the last species. Richard (Flora Nova? Zelandia?, p. 249) described it from other and 

 less perfect individuals, aided by Forster's MS. in the Museum of the Jardin des Plantes at Paris. He how- 

 ever does not notice its affinity to Celmisia, and considers the C. coriacea as probably a variety of it, though 

 Forster's figures essentially differ in general appearance, and other characters are found in the parts of the 

 inflorescence of no less importance, the achamia described by Richard being "silky and stipitate" (attenuated?) 

 at the base. Mr. Cunningham, in his ' Prodr. Flor. Nov. Zeland.,' first noticed the probable relation existing 

 between these last two species and Celmisia (Cass.). The scales of the involucre in all the New Zealand spe- 

 cies, except C. vernicosa, are narrow and almost subulate, becoming recurved and finally squarrose in the older 

 capitula ; this is, however, a variable character. 



I may here mention another little-known New Zealand plant, originally discovered by Forster, and called 

 by him Arnica oporina (Forst. Prodr. n. 290) ; it is nearly allied both to these and the former genus Pleuro- 

 phyllum. I have carefully examined specimens from Dusky Bay, gathered by Mr. Menzies, and others from 

 Chatham Island, received from Dr. Dieffenbach. The achaenia are ribbed and hairy, the pappus rigid, rather 

 scanty, pale-coloured, scabrous, and of very unequal seta?. The tubes of the corollas in the ray are glabrous, in 

 those of the disc slightly hairy. In both flowers the arms of the style precisely resemble those of Celmisia and are 

 very long, those of the disc with short papillose extremities. A comparison of this plant with the genus Chiliotri- 

 chum of Cassini, (published in DeCandolle's Prodromus, vol. vi. p. 216, and Hooker's Icones Plantarum, vol. v. 

 t. 485) does not enable me to detect any generic distinction : the arms of the style in the flowers of the ray 

 are indeed rather longer in the latter and slightly attenuated upwards, and the achaenia are glandular and not 

 hairy. Both approach very closely the genus Eurybia, Cass., or Olearia, Mcench.

Dubii generis. 



Amongst the plants collected in Lord Auckland's group, are two apparently belonging to the natural order 

 Composite, but which, in the absence of flower or fruit, I am unable to place under any genus. One of these 

 may belong to Gnaphalium, but is quite different from any New Zealand or other species which has come under 

 my notice. The only specimen of it which I possess was gathered by Mr. Lyall, and consists of apparently a 

 few radical leaves, or probably of a young plant whose stems are not yet produced upwards.

 folioso, foliis confertis patulis obovato-lanceolatis subspathulatis obtusis integerrimis planis medio 

 obscure uninerviis utrinque lana laxa molli albida vestitis f-1 unc. longis 4-5 lin. latis. 



Hab. Lord Auckland's group; on the sea-beach, D. Lyall, Esq. 



The woolly substance which entirely clothes the leaves and stem of this plant is formed of simple, terete, 

 transparent, matted filaments, similar to that of Gnaphalium luteo-album, L., to some states of which this bears 

 a good deal of resemblance. It may with equal probability be referred to a species of Heliehrysnm, and except 

 that the apices of the leaves are not apiculate or mucronate, it has much the appearance of young plants of 

 H. apiculatum, Lab. 



The other plant, if I am right in referring it, as I do with little hesitation, to Composite, forms one of the 

 most handsome shrubs or low trees belonging to that natural order. It was also detected by Mr. Lyall, from 

 whose specimens I shall here give a short description : —
