is probably right, however, in referring it to f. stenophylloicles rather 
than to f. montana, as comparison with f. Montana gathered by Mr. 
A. Wilson on Denton Moor, Ilkley, May 1901, seems to indicate. 
The limits of the two forms are however vague, and the plants need 
better descriptions.” W.I.

If the view he accepted that true H. vernicosnm should have ‘stengel 
olme Zentralstrang und ohne Aussenrinde,’ then Mr. Ingham’s plant 
should be named H. intermedium var. tenellum (Bth. et v. Bock.j, 
( Drep , intermedins var. tenellus Bth. & v. Bock.). I am re-examining 
my II. vernicosnm forms, but as yet I have not found a British plant 
agreeing with the new requirements ! I have examples exhibiting 
all the characters of II. vernicosnm in the strongest possible manner, 
without the characteristic stem structure. It is impossible to class 
these under H. into'medium, and I think the best course would he 
for the present to retain them as H. pellucidum Wils. A specimen 
so named of Wilson’s gathering has very plicate leaves, short acumen 
and nerve, narrow cells and translucent walls, with two rows of basal 
cells coloured purple, but the stem has a distinct cortex and no trace 
of a central strand.” J.A.W.

A remarkable form on account of the copious rhizoids from every 
part of the leaf, apex, base, both sides of lamina, margin, and nerve. 
On some leaves there is a row of rhizoids extending all along the 
surface of the nerve.” J.A.W.

is considerable difference between these two examples of var. vircscens 
Schp. By a liberal interpretation of the characters both may he 
accepted, but the Kettlewell plant is much the most satisfactory. 
I am inclined to think that the Beck Dale plant is an irrigatum 
derivative of II. commuted um rather than of II. falcatum. I found 
here and there typical broad based leaves with thin hyaline alar 
cells, though they are often yellow and incrassate, and odd stems 
may be found with thick matted red tomentum. The nerve is only 
about half as strong as in the Kettlewell apecimens. If placed under 
var. vircscens, Mr. Ingham’s plant should have some note to indicate
