Hypnum aduncum (Kneiffii) var. intermedium , forma laxifolia 
Sanio. (teste Renauld). Walton, S. Lancs. (59). 5 Jan., 1899. 
J. A. Wheldon. “I gathered exactly the same moss at Naburn, 
Nov. 4, 1899. On revisiting the place Apr. 20, 1900, I found the 
lax leaved stems had developed into type. Therefore I think forma 
laxifolia of no consequence.” — W. Ingham. “This does not 
merge into the ordinary form here always, even when a little 
more robust, having lax leaves; but, as Mr. Ingham suggests, it 
is a mere state.”—J. A. Wheldon. 
H. Wilsoni var. hamatum Ldb. (teste Renauld). St. Annes, W. 
Lancs (60), July, 1898, and Southport (59), May, 1898.—J. A. 
Wheldon. 
H. lycopodioides Schwgr. St. Annes, W. Lancs. (60), March,

JI. fluitans var. Amelia Sanio. (teste Braithwaite) Skipwith 
Common, v.c. 61. 19th July, 1898. W. Ingham. 
- var. gracile Boul. Longridge Fell, W. Lancs., 12 Apr., 
1900. J. A. Weldon. “Aftercareful examination and compari¬ 
son, I make this Hyp. riparium L. The alar cells are wanting, the 
nerve is short, the ct 11 s are too short and wide for H. fluitans, and 
although there is a suspicion of slight toothing at the apex, the 
margin is entire. The leaves certainly are not so spreading as 
usual, and are inclined to be secund and falcate, but otherwise I 
call it good ‘ riparium ’.”—W. Ingham. “ Some forms of II. fluitans 
(notably group obsoletum ) have wider cells and short nerve. H. 
riparium is exceedingly rare or unknown on our elevated fell lands. 
The specimens are from near the place where I gathered var. 
gracile named by Renauld, but may not be the same. This form is 
frequent on nearly all the W. Lancs, fells.”—J. A. Wheldon. 
“ Certainly H. fluitans . I should be a little doubtful of the var. 
gracile ; the only specimen I have of that does not look quite the 
same ; Renauld too says the leaves of that var. are strongly toothed 
in acumen. I should have thought it an ‘ allotropic ’ form of the 
‘ group obsoletum ’ plant from that locality.”—H. N. Dixon. “ Mons. 
Renauld refers this to var. gracile Boul. There is a very slight ad¬ 
mixture of the obsoletum form mentioned by Mr. Dixon, probably 
added accidentally, during the drying process. This form of fluitans 
occurs from the sea level in Lancashire to over 2000 ft. in W. 
Yorkshire (Ingleboro).”—J. A. W. 
H. exannulalum var. near stenophyllum, but with fewer pinna?, 
broader leaves, shorter nerve not entering acumen, and entire 
piliform leaf apices. Southport, June, 1898. J. A. Wheldon. 
“This to my mind is undoubtedly H. aduncum Hedw., and I should 
like Mr. Dixon to see it.”—W. Ingham. “ After careful exam¬ 
ination I think Mr. Ingham’s view is the right one. The narrower, 
shorter nerve, practically entire leaves, and broader leaf base, are 
points which incline towards H. aduncum, but in addition to these 
there is a certain appearance characteristic of the basal cells of all
