W. cuvvivostvis v. commutata Dixon, Cwm Dyfnant (42), 12/05. 
H.H.K. “ This plant has the habit generally associated with the 
var. commutata , but I find the leaves and occasionally even the stem 
distinctly papillose. The cells, however, are somewhat elongate, 
and as the papillosity is variable, I should be inclined to refer it 
to a transitional form.”—W.E.N. “ I agree that it is a transitional 
form, but approaches var. commutata rather nearly.”—H.N.D.; also, 
Roseneath (99), 9/03. E.A.; v. scabra Dixon, (?) Achmore Burn 
(88), 7/05. E.C. “ This is another not wholly satisfactory plant 
as, although the leaves are moderately papillose, the stems are 
nearly smooth, and these are generally highly papillose in marked 
examples of the var. I am inclined therefore, mutatis mutandis , to 
apply the same remarks to this plant, as to the last.”—W.E.N. 
“ I quite agree with Mr. Nicholson’s remarks on this.”—H.N.D. 
IF. vevticillata Brid., c. fr., Great Doward (36), 9/01. E.A. 
“ Although there are a few sterile stems of W. vevticillata in this 
gathering, I make the whole of the fruiting plant to be B. topliacea 
Mitt.”—W.E.N.; also, Cramond (83), 1/05. J. McAndrew. Com.

T . inclinatum Dixon, Garrarus, Co. Waterford, 7/02. C.H.W. 
“ I am unable to distinguish this plant from T. flavovirens Bruch. 
The leaves are more strongly twisted when dry than is usual with 
T. inclinatum , and rather more spreading when moist. These 
characters, taken in conjunction with the maritime habit rather 
point to T. flavovirens, though I should not like to speak too 
definitely on the subject. I have found a very similar plant on a 
crumbling wall by our Sussex coast, which I have referred to 
T. flavovirens. As I am acquainted with it in the field, T. inclinatum 
seems to be rather a mountain plant. It especially delights in the 
sandy detritus by the glacier streams in the limestone Alps.”— 
W.E.N. “ I quite agree with Mr. Nicholson’s remarks ; the two 
plants are very difficult to distinguish, but even without the 
characters pointed out by Mr. Nicholson, the presumption from 
the habitat and locality would strongly favour T. flavovirens .”—
