CLIMACIACEAE. 241 
The Kew specimen of B. novae-seelandiae shows some leaves with 
very decided though short, glistening, occasionally reddish, ecuspidate 
points, quite reminiscent of Rhacocar pus; this however is exceptional, 
and most of the leaves are normal. This character occurs occasion- 
ally in other Australasian specimens of H. imberbe, notably in one or 
two specimens at Kew of the form described as H. Drummondii 
(Tayl.) Jaeg. “Tt | is not, however, correlated with any other character 
and is only sporadie. H. Drummondii was based practically entirely 
on the supposed nerved leaves, but as Wilson has pointed out, this 
is fallacious. he narrow linear median basal cells when hi ghly 
coloured and extending rather high in the leaf give fhe appearance of 
a nerve, and this has ‘led to the erroneous description of H. Drum- 
mondu as Bae nerved leaves. In other respects it agrees with the 
normal forms of H. imberbe. It appears to fruit more poems 
aly abies than in Europe; it fruits, however, much less com- 
car than Hedwigia albicans. It is probably not very common in

This fine rupestral species is fairly common and often abundant. 
The red, glossy hair-points of the leaves form a very beautiful micro- 
scopic object, and the plant is at onee recognizable under the lens 
by these alone. The New Zealand plant was formerly considered 
to be identical with the wide-spread R. Humboldtt; it is now separ- 
ated, on rather slight characters drawn from the perichaetial leaves, 
but it may be doubted whether it be more than a slight racial segre- 
gate.

A very common plant in the north temperate zone, but little 
known in New Zealand. It rarely fruits, and the ster rile plant is 
alone, I believe, found here. In its dendroid habit it is perhaps most 
closely imbricated, shorter and wider at the points, with a shorter 
nerve, ceasing distinetly below the apex, and quite different aes < 
serration. ae
