Nn. sp., Var. Caleta Nov. Seel., insula ssiitealin, Pakihi, R. Helms leg., 
1887, et mis. 1888.” Both these are certainly D. plurisetum, and I can see 
nothing to separate the latter as a variety. Some of the capsules in the 
Greymouth plant have the struma scarcely developed, but these are usually 
old and shrunken, and others _ it fairly well sea eo It probably 
exists in other herbaria as D. dicarpum or D. polysetu 
D. plurisetum is a good species, in habit and in the plurisetous inflor- 
escence resembling athe the polysetous form of D. dicarpum, but entirely 
different in the elongate upper areolation, the remarkably spinose nerve, 
and the leaves not biplicate below, and dentate in the upper portion only 
of the subula, which is much broader and shorter. The subula, inde 
is very short compared with most of the a — species. The 
of the fruiting characters of D. argutum Hampe (D. Wile a M.), and 
treat it as a regional race of D. dicarpum, on account of its absolute identity 
in aa argc with that species. D. plurisetum, however, throws a 
new light on the position. It clearly forms a connec ting link between 
D. p eesti and the remaining species of Dicranoloma. Tt has many cha- 
racters in common with D. dicarpum ; the peculiar armature of margin 
and nerve, the wide border, and the sporophytic characters generally are 
all very similar in the two, and the upper areolation in D. plurisetum shows 
just so much differentiation between the marginal and the juxtacostal 
cells as to indicate a clear affinity to D. dicarpum, while at the same time 
the inner cells are so pronouncedly elongate and porose as to show no 
departure whatever towards the Le ma type. It therefore strongly 
confirms the accuracy of Renauld’s view of D. dicarpum as a noloma.
