To anyone unaequainted with the wild parts of Kew Gardens it 
re ra 
interesting aquatic mosses, and, without doubt, all these are quite 
wild. 
w common species are absent from the list, while, on the 
other hand, several rare species occur in it. 
Amb : de gium. Kochii, known only from one or two counties in 
ingland, occurs ae Kew in a | few a by the Thames, together 
ith A. "variun , Fissidens crassipes : Physcomitrium pyriforme, 
Labo pol pae Cine lidotus Jendinadoides, &c. 
= other interesting species, Mniwm cuspidatum, M. stellar 
Donii, Tortula intermedia, Trichostomum tortuosum, 
Easels ypta streplocar “pa, Barbula lur -— and Neckera crispa have 
been noticed only in or about the rockery ; and, for reasons 
mentioned above, their origin must unn doubtful. 
On the other hand, the following species (amongst others) are 
certainly wild :—P olytr ichum formosum, Plagiothecium borreri- 
anum, Pleuridium axillare, P. subu ulatum, P. alternifolium, 
Funaria fascicularis, Pottin a Tortula marginata, 
Fissidens pusillus, F. exilis, F. ina "us, F. viridulug, Lepto- 
bryum pyriforme, Acaulon ah aay and V var. mediterraneun 
androgynum, Dicranum Bonjeani, Thamnium alopecur 
Eurhynchium piliferum, and E. megapolitanum. 
I have to thank Mr. George Massee for a list, seem panied by 
specimens, of 20 Kew mosses, collected hy him in previous years. 
Five of them, which I have not been able to refind, x wot bei 
in the list on his authority. In most cases the habitats of these 
species have become changed through improvements, and the 
species are very probably now lost. 
George Nicholson I am greatly indebted, not only for 
fusitshing me with a list of about 40 mosses already recorded for 
Kew Gardens, but also for showing me the a em for 
many of these, and for helping me to search for ne es, 
The nomenclature re abe is that of Dixon’s “ Students’ 
Handbook of British Mosse 
I have placed Nnm of the more interesting species in the 
Kew Herbarium.
