Quite distinct in the or stb long leaves, crisped when dry, not 
sheathing at the base, and the capsule on a very short, slightly curved seta, 
soon becoming lateral by innovation, and remaining for some time on ‘the 
stem. 
Cardot retains the southern plant (as B. Mossmaniana), distinguishing 
it from B. norvegica by the leaves more crisped when dry, and the synoicous 
or polygamous inflorescence. The leaves are certainly. more crisped when 
dry than in ihe northern plant, but I have New Zealand plants with the 
leaves less crisped than usual, and which do not ifler materially from some 
ritish plants. The inflorescence can ail be insisted on, since in 
B. magellanica Aongstr., which is united by Cardot and others with 
B. Mossmaniana, the inflorescence is autoicous. 
Beckettii . ined., type ex Mus. Berol., is quite inseparable. 
R. Brown distinguishes his B. hallerianoides by several characters from 
the European plant, but these characters will not stand, and as regards 
the latter are indeed incorrect. :

So far as I am aware this has not been collected since its first gathering 
by Haast. It is represented at Kew by a single tuft only, a short dense 
plant of a glaucous green, the leaves rather crisped when dry; it is recog- 
nizable at once under the microscope by the well-defined nerve, and small, 
distinct, 
somewhat sheathing, but is not markedly so n the species belonging 
to the section Vaginella. The margin is either at or narrowly recurved.
