character, in giving e. g. Campylopus symplectus Stirt. varietal rank 
under G. subulatus on the sole ground that certain cells of the nerve 
in transverse section have in the one a diameter of 13-18 p, and in 
the other of 10-14 pi (cf. Ann. Scott. Nat. Hist. xiv. 108 [1905]). 
In the succeeding notes I have not thought it necessary to include 
some of Stirton’s plants which have already been dealt with elsewhere ; 
e. g. Grimmia retracta Stirt., Campylopus ILuntii Stirt. 
I have to express great obligation to Mr. Gepp for much help in 
the preparation of this list; and to Mr. J. li. Lee for looking out 
certain references only to be obtained at Glasgow. 
The order followed (and the nomenclature) is that of the Student's 
Handbook of British flosses. The locality in brackets, following 
the name of the species, indicates the specimen or specimens in 
Stirton’s herbarium on which my notes were based. This was 
wherever possible the type or original gathering, or one to which the 
author refers in his description as showing the characters on which he 
relies. Stirton does not, as a rule, indicate the specimen which he 
considers as type ; but when a packet is labelled as “ original,” or 
“ the most characteristic plant,” I have selected that, when there 
m'mht be a doubt; this however rarely arises. In a few cases, it will 
be noted, Stirton failed to indicate any locality for the plant described. 
Stirton under his descriptions of his species frequently adds 
“ described in ” or “ published in 18(55, 1866 ” or some other early 
date. This is, however, misleading. The dates refer to meetings 
when Stirton exhibited and called attention to mosses which he 
described later on, but no descriptions which would constitute publi¬ 
cation were published or even given at the meetings. 
The early volumes of the Proceedings of the Glasgow Nat. Hist. 
Soc. frequently refer to these exhibits, and testify to Stirton’s great 
activity at that time, and to the large number of newly detected 
species with which he enriched Scottish and British bryology. 
The dates given in the present lists, extracted by Mr. Gepp from 
Stirton’s published papers, give, I believe, the first publication in all 
cases.
