contained much additional material, among it species which 
Miss Hughes had been obliged to place among the “ dubiae.” 
The present “ Notes ” are the result of her examination of these 
collections. It is very satisfactory that her conclusions, tested 
on a considerable number of new specimens, were found to hold 
good in nearly all cases. As to the ‘“ dubiae,’’ one of Reader’s 
species, 8. acrociliata, was recognised as an accession to her list 
of Australian species, whilst another, S. eremophila, was found 
to cover the bulk of S. rudis, as understood by Miss Hughes, but 
not the original S. rudis of Sprengel, which, on the examination 
of a better co-type, has turned out to be S. pubescens. A third 
species, S. Luehmannii, proved to be the S. Drummondii of 
Steudel, and a fourth, not accounted for in her original paper and 
missed in the Index Kewensis, takes now the place of her S. 
lachnocolea. The other “ dubiae ”’ are all species, the elucidation 
of which will require the consultation of continental herbaria. 
Two further additions to the list of Australian species resulted 
from her examination of specimens collected in New South Wales 
by R. T. Baker and F. v. Mueller respectively. Interesting is 
the discovery that S. aristiglumis of F. v. Mueller was based on 
a really non-existent character which by the rules of nomen- 
clature en yet remain evident in the name of the species. 
mber of species of Stipa in Australia is ci up to 
42 by the “ Notes,’ whilst 6 are left among the “ dubia
