perfectly mature. The lid is very shortly and broadly conical, usually 
obtuse, and seni than in B. ksi 
bnormal forms of the species, of f which the type figured by Hedwig 
is one, have the capsule very short, sometimes as broad as long, and the 
neck reduced to the smailest dimensions. In such cases, however, some 
capsules will show distinct traces of neck, sufficient to distinguish it from 
B. pachytheca 
Minute axillary bulbils, oblong, crowned with rudimentary leaf-apices, 
are frequent among the upper leaves. Correns describes and figures from 
the South American B. bulbillosum Mont. a somewhat different form of 
bulbil from that prevalent in the New Zealand plant, which is similar to that 
of B. atropurpureum, and for that reason the species have been considered 
distinct, contrary to Mitten’s view in the Musci Austro-americani. How- 
ever, I have recently examined original specimens of Montagne’s plant, and 
or that two forms oi bulbil occur. In an se I have no doubt that 
Mitten is correct in referring B. bulbillosu vie B. dichotomum. Without 
are too, some of the related Australian species will have to be reduced 
o B. dichotomum 
I have examined Wilson’s specimens of B. annulatum, and have no 
hesitation in referring it here also; the differences wena onthe recurving 
of the leaf-margin, the form of capsule, &¢.—

with B. rea rece that they are also identical with this, which must 
have the priority. I am far from claiming to have reached finality with 
this. the Handbook says, the New Zealand plant is very closely allied 
to the European B. erythrocarpum; but there are some differences in the 
vegetative parts which seem to me to make it, at present at least, 
inadvisable to unite nea

narrowly clavate, tapering very gradually into the seta by a much

- varieties of the Fi. N.Z. are perhaps hardly worth maintaining.
