276 BRYOLOGY OF NEW ZEALAND. 
the present is a slightly larger and less compact’ plant; the leaves are 
larger, very obtuse, quite nerveless, when dry decidedly glossy, of a 
hinner, more translucent. texture, and often somewhat shrunken 
when dry, and wrinkled. In typical L. divulsum the stems are usually 
more densely er eave  SHENELS, less robust, more rigid, of a glau- 
cous green colour, the ves frequently slightly pointed, with a eit, 
single nerve of variable gaa h and distinctness; when dry they are 
less glossy, of a ore 2 opaque and slightly stouter texture, so that the 
branches may ber entirely unaltered when rH, e inflorescence e 
L. clandestinum is “seid by Wilson as oie with the 
flower amongst or n the leaves of the fertile pesca (Dhsllautoieous), 
that of L. ddacen : as die hay however, ranks them both 
as pseudautoicous, i.e. phyllautoic 
On the other hand, I have cee ee of L. divulsum which are 
quite as robust as L. L. clandestinum. The leaves in L. divulsum show 
a great diversity in the nerve; I have found ht i plants with nerve- 
less leaves but all the other characters of L. divulsum, and Wilson 
also found forms of L. divulsum with nerveless leaves. 
The areolation also presents certain differences, though I am 
uncertain if they can be relied upon in all cases. The upper cells in 
L. divulsum are almost or quite isodiametrical (**punctiform’’ Wils.), 
while in LZ. clandestinum they are rarely so, but are shortly, minutely 
elliptic. The alar cells in L. divulsum form £10 ss clearly delimited 
group, being more spread over the whale" alae region and passing 
more gradually y into the remaining cells 
clandestinum may also be confus by with Weymouthia mollis, 
some “forms of which are exceedingly difficult to separate. The longer, 
narrower, sigmoid cells of W. mollis, less incrassate and very pointe 
and prosenchymatous, will perhaps ried separate them, a there 
is I believe a slight constant difference the alar cells, those of L. 
clandestinum being somewhat elongate, with very sinuous wats: those 
of W. mollis more isodiametrie and less sinuous. 
Acrocladium auriculatum may easily be confused in the field with 
clandestinum, but has more acutely cuspidate branches, and the auri- 
cles composed of large, thin-walled hyaline ce 
Mr Gray sent a very remarkable es of the present plant, 
from Mt. Bruce, Wairarapa; pendent, abundantly and Sen eahy elothed 
with long, delicate, minute-leaved, flagelliform branchle 
L. clandestinum is tit Rae in both islands, and dir to Tas- 
mania and Australia
