Bellia straminea cannot be separated from B. nervosa. An exam- 
ination of Beckett’s — and figures of the Stewart I. Daltonia 
straminea shows that e diagnosis he emphasizes no characters as. 
distinguishing it from "D. nervosa except the inflorescence; the straw- 
colour and the smooth seta are the only characters that suggest a 
eo 
to the inflorescence, Beckett says ‘*' The pate te inflorescence 
dues separates it from that s species,’’ i.e. B. nervo 
mention what inflorescence he attributes to B. nervosa, hie as a matter 
of fact it is dioicous also. In fact the dioicous inflorescence is given 
by Brotherus as Keo of the Sabi characters of Bellia, that of Dal-

To these characters Brotherus (Musci, loc. eit. ) adds that B. straminea 
is a robust plant with suddenly narrowed yee si B. nervosa 
colour is at first sight distinctive, as Bell's Stewart I. moss 
isa bright orange brown, while B. nervosa is generally of a dull, pale 
green; but this ‘colour is not correlated with any other characters, 
least of all size, because Bell’s plant is generally no more robust

tuft that it is absolutely of no value. Beckett’s description of the 
leaves ; of B. straminea is ‘‘linear-lanceolate, tapering gradually to a 
point’’ (it may be remarked that they are ‘figured rather as oblong- 
lanceolate, by no means Hnsdclanaegiates and this is entirely borne 
out by many of Bell’s specimens. 
There remains only the seta. It is true that the seta in the orig- 
inal gathering of B. nervosa from Lord Auckland Is. is distinctly 
papillose at apex, while that of Bell’s plant is smooth, or only slightly 
roughened at apex; but the latter is equally the case with other plants 
of the North and South Islands, which with smooth setae have the 
e green, not yellow colour of the Stewart I. plant. This is. 
notably the ease with several gatherings I have from Mt. Bruce, Wai-.
