EXTRACTS FROM M.E.C. NOTE BOOK FOR 1897. 
Andrecea petrophila Ehrh. Loc., date and coll. ? Was A alpina 
Sm.—W. E. Nicholson. 
Oncophorus virens , Schimp. Ben Lawers. Rev. C. H. Binstead. 
“ Prominently shouldered leaves, very narrow above, O. Wahlen- 
bergii Brid. I think” (1896 Exchange.) — W P. Hamilton. 
Dicranum Bonjeanii var. rugifolium, Boswell. Strensall. Yorks., 
Nov. 1888, J. A. Wheldon, (1896 Ex.), same loc. Feb. 1897, W- 
Ingham, who says “very abundant also on Skipwith Common, near 
Selby; stems very tomentose.” 
“ Upper leaves decidedly wrinkled and rugose when dry. , but few 
only seem so for whole length. Vide Hobkirk Syn. Addenda 
opp. p. 1.”—R. de G Benson. “I think this variety should be 
retained Its contorted leaves give it a very distinct appearance 
when growing. The var. juniperifolium occurs on the same tract 
of Strensall. Does not fruit ? Boswell confirmed a Strensall 
gathering of mine. Where does his original description occur ?” — 
J. A. Wheldon. 
“ In its most strongly marked condition a striking variety, but I 
have some doubt as to whether it should not be considered a form 
rather than a variety. My reason for describing D. Bonjeani in the 
Handbook as ‘transversely undulate when moist’ was that D. 
scopanum frequently exhibits a tendency to waviness in the leaf 
apices when dry , and an examination of the leaves in this state 
alone would be unsafe; it was not intended to imply that the 
leaves in D. Bonjeani were not undulated also when dry, though it 
is rarely they exhibit this so strongly (or throughout their whole 
length) as in the variety in question.” — H. N. Dixon. 
Fissidens adiantoides var. collinus Mitt, fide Dr. Braithwaite. 
Bletchworth, Surrey, 9.96. Coll. E. S. Salmon. 
“ In my opinion undoubtedly F. decipiens De Not. The areola- 
tion exactly agrees. The leaf point is occasionally a little more 
acuminate than is usually the case in F. decipiens , which is the only 
difference I can find, and that far from constant. Though usually 
rupestral, it grows about Northampton in dry grassy spots.”—H. N. 
Dixon. Mr. Wheldon and several members say it is a small or 
dry ground form of that plant. Mr. Salmon afterwards compared 
it with a specimen at Kew Herbarium from Undercliff, Lyme Regis, 
W. Mitten, Aug., 1885, and found “ the two were identical in the 
incrassated small (comparatively) areolation and prominent pale 
border.” And also with authentic F. decipiens De Not. “As Dr. 
Braithwaite states (Moss Flora 1, 84A) he can find no difference 
between the cells of collinus and adiantoides , it seems possible that 
the specimens of Mitten’s collinus from the original locality the 
South Downs may be something different.”—E. S. Salmon. 
It is necessary that authentic specimens should be examined to 
clear up the matter.
