ACROBOLBUS Nees 
AcCROBOLBUS WILsont (Tayl.) Nees 
Known only in one ravine, where it has been found in 
three places, among mosses on wet rocks and on trees. 
This rare species has only been elsewhere found, in the 
British Isles, sparingly in the west of Ireland. It is a 
very difficult plant to detect in the field, as it usually 
grows as scattered stems, and is of an inconspicuous 
green colour, resembling the lighter-coloured forms of 
Saccogyna viticulosa, which is one of its accompanying 
species. It is also accompanied by Hymenophyllwm 
wnilaterale, Plag. spinulosa, Radula aquilegia, Metz. con- 
qugata, Lej. cavifolia, Thuidium tamariscinum, Eurhyn- 
chium myosuroides, Hylocomium splendens, H. lorewm, 
etc. Fruit, not yet exserted, was present in November. 
Male inflorescence was not seen with certainty. 
W. Hicuianps.— W. Inverness: Resipol, on tree in 
ravine with fr., Nov. 1901 (Macv.); do., among mosses on 
rocks, 1903 (Macyv.).
