I have seen no New Zealand specimens of this, but it is recorded 
by Brotherus from “ Victoria, Tasmania, and New Zealand.” It is a 
interesting plant, combining with a very close relationship to D. Menziesii 
a totally different aspect from most forms of that species, and also an 
ey different leaf-outline. The type specimen, which I have examined 
in Hampe’s herbarium, as well as a part of the original gathering for which 
I am indebted to Dr. Brotherus, show a short, straight leaf, scarcely longer 
in the subula than in ne expanded part, and with a few denticulations 
at most towards the a 
ampe’s description “of the leaves as “ subenervia ”’ is rather misleading, 
especially as he emphasizes it by his note, ““ab omnibus generis abnorme, 
loco nervo, striae paucae rectae ad folii basim aagunt.” For the nerve is 
constantly distinct, and, indeed, well marked, in the upper part of the leaf, 
and while towards the base it becomes, it is true, very faint and incon- 
y any means to a want of development. It is, indeed, a rat er sur- 
prising fact hit this nerve, so inconspicuous as to be often almost invisible, 
belongs to the type Toxoneuron, the most Ae, developed, histologically, 
of all the forms of nerve in the genus. euter are small, 10-14 in 
number, and the remaining cells, epidermal as well as hypodermal, all more 
or less stereid and subsimila 
have not seen the fruit, but judging from Hampe’s description 
C seta co damp &c.) it exhibits some marked differences from that of 
D. Menzies

This widely distributed species in the Australasian region is clearly 
marked by the deeply plicate leaves, together with the character of its 
areolation (c/. figs. 8b, 8c). In this latter respect D. plurisetum is perhaps 
e only species which might be confused with it, but there the juxtacostal 
alle of the subula are much longer than in the present nay the sharply 
spinose dentation of the leaves in D. dicarpum exten uch lower in the 
leaf than in D. plurisetum, while the latter has a much Sage and more 
distinct hyaline border in the lower part of the leaf, which is not biplicate 
as in D. dicarpum.
