Some AUSTRALASIAN SPECIES OF BREUTELIA. 
BrotTHervs in his treatment of Breutelia in the Mus 
pp. 653-660, separates certain species under “ Bubreutelia® 
Broth. from the Section Acoleos (C. M. as Section of Bartramia) 
by the form and position of the leaf-base. In Acoleos this is

the “ weniger kraftige ” habit of Acoleos as against ‘mehr oder 
minder kraftige’’ plants of Hubreutelia, there are no separating 
characters. This character crea from the leaf- a is no doubt 
a well-marked and useful on the case of some of the more 
robust species, where the Paar ay is more or less > abeapliy reflexed 
from the erect or somewhat amplexicaul base, which is often 
distinctly wider above—at the shoulder—than at the insertion ;
