76 BRYOLOGY OF NEW ZEALAND.

science made by this great bryologist during the course of 
On the other hand, further and very welcome light a = thrown 
Brown’s plants by ‘the kindness of Mr. G. Brown, son of R. Brown. 
The santioy parts of this bulletin having come under his notice, Mr. G. 
rown wrote informing me that the bulk of his father’s collection remained 
in his hands, though some parts had unfortunately perished. Be need 
he kindly sent me specimens of all that he could find of R. Brown’s 
published and unpublished species, as well as a large amount of unnamed 
material; and these have been of inestimable value, embracing as the 
do a large aie of types of species not represented i in the Christchurch 
Museum collectio 
Before sities 2 the further study of the Dicranaceae I wish to make 
one or two additions and corrections to Parts I and II. 
Part I, p. e synonymy ‘of Dicranoloma Menzies add 
“ Leucoloma calymperoideum C. M. in Hedw., xxxvi (1897), p. 359.” I have 
received part of the type material from the Berlin Museum, and find 
that it is ae identical with this species. 
Part I, 9.—Drcranoloma chrysodrepaneim. Further material tends 
= diminish Phe distance between this and D. robustum. The leaf subula 
en border may be scarcely distinct (and specimens of D. robustum 
sometimes show an equally defined border) ; and altogether the validity 
of the cane ae very dubious. The setae are generally single in 
each perichaet

(1894), p. 417, t. 33. 
The original gathering of Grimmia diminuta (limestone rocks near 
Castle Hill, Christchurch, Mar., 1891; coll. R. Brown) proves to be a:

and cygneous (in S. Cardotii it is at most slightly curved only); and very
