part of the leaf where the limb becomes very wide and prominent. 
It is necessary to point this out, as the first glance at the systematic 
Rae assigned to ‘‘ Barbula crispata”’ by Miiller might lead us to 
ect the opposite. In the Genera Muscorum, p. 458, we find B. 
sak ai Hampe placed with B. Brebissonii Brid. in the section “* Syn- 
trichia limbate” of Barbula—a section which is defined as follows :— 
‘‘ Blitter mit einem dicken Saum (limbus) umgeben, welcher aus 
mehreren Schichten dichter << megs und ganz ripponarhg 
ist.” 
wller remarks that onl species are known nue 
section, and that each of these SS constitutes again a ee 
itsel or B. crispata Miller proposes the name Ea a 
einfaches ni he limbatum bildet.” From the characters given to 
the section in which the moss is Pee be and the use of the word 
Pachylomella, one would infer that the limb of the leaf in B. crispata 
( =(., mnioides) was multistratose in some part of the leaf. This,

forms an important distinguishing charact 
Among the specimens in Mitten’s a oe I have found a 
the species, and which I propose to eeine as a new variety under 
the name anguste-limbatus. The specimens in question occur with 
the type, and are labelled ‘‘ Pine Hill, Dunedin [New Zealand], 
July, 1887, leg. W. Bell, nr. 439 in part. ‘The plants of the variety 
form small olive-green tufts, 1-5 cent. high, and whilst agreeing 
completely with the type in general habit, and in the crisped and 
twisted leaves, show under the microscope constant differences in 
certain leaf characters. The leaf in shape does not differ from 
that of C. mnioides, but the ca slation, is more obscure, the papille 
of the cells are larger, and the limb is distinctly narrower through- 
Th is intramarginal above the sheathing part of the 
leaf as in the type, and at ig vig the length of the leaf is only 
8 cells wide, whereas in _the e type it is here 4-65 cells eres The 
narrow te gives the on a aeabiuasies appearance under the 
smicmooaope. The limb as a rule is much paler than in the type, 
eing sometimes almost wii, although becoming yellow in the 
older leaves. The examples are barren, and the leaves bear gemme 
of the same nature as those of C. mnioides type. 
give below a full description of C. mmioides and its variety 
auguate-linbaras, together with the distribution and synonymy. I 
wish here to express my thanks to the authorities at the Berlin 
Museum and the Herbier Boissier for allowing me to examine 
certain types in Miiller’s and Schwaegrichen’s herbaria, and to
