I have felt very doubtful about retaining this as a species. In habit 
and size it is one of the most variable of the group, and the Hookerian 
herbarium contains forms from the most spur with distant erect small 
leaves resembling D. leucolomoides, up to the most robust, with densely 
MS.) 
svalentiy ed felt the difficulty of defining it, and in the H Ra ee it is reduced 
ing it definitely from D. robustum, is the character of the nerve, which is 
on original specimens (Kerguelen’s Land, W. 250, in Herb. Hook.), and find 
it clearly of the Heteroneuron type. Moreover, it appears to be constantly 
narrower, both above and below, than in either D. robustum or on 
about 60-80 wide in the lamina, and in the subula narrowed an remain- 
‘ng well defined. The upper cells do not seem to differ eee those of 
robustum and setosum, nor can I detect any differences in the fruiting 
characters. The leaves are probably always narrower and smaller at the 
se than in the ordinary forms of robustum. 
* D. pungens, W. 27, Campbell Island,” in Herb. Hook., has a broad 
strong nerve and large wide leaves, and I believe it to be properly referred 
to D. robustum. 
Renauld, it is true, places" D. pungens under the species having t 
Leptoneuron nerve, but if this is the case with some of the weakest form 
it is certainly not so usually, nor in the type specimens. If it actually i is 
Leptoneuron ie times, it emphasizes the differences from D. robustur
