(3-)—The perichaetial leaves of the moss in question are 
perfectly smooth, whereas in H. uncinatum they are deeply sulcate. 
(4.)—In July, 1898, I gathered the Hebden Bridge moss in 
abundant fruit on the top of Burnhope Seat, in Upper Weardale, 
and have sent it for distribution this year among the members of 
the M. E. C. I am convinced that FI. fluitans v. falcatum Schp. is 
a moss that is not understood, and that is well worthy of careful 
study. — W. Ingham ” 
“ I think both plants are correctly referred to H. fluitans

Hypnum hamulosum B. & S. Ben Lawers, Perth. R. H. 
Meldrum. 16/7/91. “ This is Hyp. callichroum Brid., but it has 
been a puzzling moss to decide. The thin-walled hyaline cells of 
the base separate it from H. hamulosum .”—W. I. “I agree with 
Mr. Ingham that this has been a puzzling moss to decide. I kept 
it for long in my collection of conundrums which I attack from 
time to time. Sometimes I decided it was H. hamulosum , and 
sometimes I made it H. callichroum. When I sent it to the 1898 
distribution I was on the hamulosujn side of the fence, but that 
summer on revisiting Ben Lawers I gathered a more typical form, 
which I determined to be H. callichroum and sent specimens so 
named to the ’99 distribution. Shortly afterwards I received a note 
from Mr. Dixon mentioning that the 1891 plant had been sent him 
by Mr. Ingham queried H. procerrimum. Mr. Dixon suspected it 
was a new species and submitted it to M. Cardot who also thought it 
was new. After receiving a specimen of the later gathering and 
again examining, 16/7/91, Mr. D. considered the latter a form of 
H. callichroum , and I think there is little doubt that such is the 
case.”—R. H. Meldrum. 
Harpidium Knejfli. Drumnahon Bog, P. of Aghaderg, Co. Down, 
12/6/89.—Coll. H. W. Lett. (M. E. C i 897.) “ This is Hyp. 
exa?mulalum, (see basal areolation, stout nerve, basal margin den¬ 
ticulate). An exactly similar form from Longmynd, Salop, I had 
taken for H. Kneiflh and several critical friends concurred. A 
recent overhauling of my ‘ Harpid’ specimens, with Mr. Dixon’s 
help, renders this correction necessary. The plants are very 
slender or lax, with shorter stem leaves.”—R. de G. Benson.
