Hypnum jluitans L. Woolston Moss (58), March, 1821. Coll., W. 
Wilson (ex herb. Brit. Mus.). Comm., E. C. Horrell. “ All 
belonging to aggregate H. jluitans . but all the packets do not 
contain the same form. Mostly belonging to group amphibium , 
and one packet contained a good specimen of var. Jeanbernati Ren. 
f. tenella Ren.”—J. A. Wheldon.

H. Jluitans forma? Summit of Screel, Kircudbright, 26 June, 
1900. W. P. Hamilton. “Mr. Hamilton agrees with me that 
this plant, notwithstanding its less falcate leaves, belongs to group 
falcatum. I should refer it to the var. Holtii, although Mr. 
Hamilton) points out that in the ‘Moss Flora’ the leaves of this 
latter are said to be not glossy. In original specimens from Mr. 
Holt I find them quite as shining as in most forms of group 
falcatum .”—J. A. Wheldon. “ I think Mr. Hamilton’s H. fluitans 
must be var. Delamarei R. & Card. My scrap of that seems to 
agree well, but it would be well to submit it to Mons. Renauld.”— 
H. N. Dixon. “ Appartient certainement au groupe falcatum 
comme vous et Mr. Dixon l’avez reconnu et non au group Rotae. 
File est intermediaire entre le var. Anglicum Sanio f. Holtii, et la 
var. Delamarei R. & C. Je constate aujourd ’hui que cette derniere 
var. est extremement voisine de la var. anglicum (f. Holin') que je 
ne connaissais que par la description quand je l’ai fond6e avec 
Cardot. II vaudra mieux je crois conserver 4 votre plante collectee 
par M. Hamilton le nom de v. Anglicum Holtii. Dans la var. 
Dela??iarei les tiges sont plus regulierement pennees et les feuilles 
plus fortement falciformes.”—F. Renauld. 
- (amphibium, var. Jeanbernati Ren. Skipwith Common 
(61), Aug., 1900. Coll., W. Ingham (teste Dr. Braithwaite). “A 
robust form which may be var. datum Ren. et Arnell.”—j. A. 
Wheldon. “Var. Jeanbernati Ren .forma data ad var. datum 
Ren. et Arnell transiens. La plante de Medelpad est plus robuste 
plus rameuse k rameaux dpais k foliation dense.” 
- var. Jeanbernati Ren. f. Holleri Sanio. Back side of 
Tarnbrook Fell, Wyresdale (60), Sep., 1900. A. Wilson & J. A. 
Wheldon. (teste Renauld). “ Perhaps so ; but I should much 
like to know how this differs from var. falcatum Schimp. I have 
gathered exactly the same plant in Weardale, and Mr. Dixon agrees 
that mine is a weak state of var. falcatum Schimp.”—W. Ingham. 
“ I think these specimens are correctly referred to group amphibium , 
which differs in shape of leaf, colour and basal cells, from group 
falcatum, and in the latter as a rule the leaves are more strongly 
and regularly falcate-secund. Intermediate forms occur however 
which are difficult to place, and which Mons. Renauld considers
