cribrose, and of a paler red at any rate than in the typical apocarpa\ 
in fact to my eyes (and Mons. Theriot agrees with me) scarcely 
distinguishable from G. conferta in anything but the non-cribrose 
teeth. Of course, at the same time, this does not affect Mr. 
Nicholson’s conclusion that Mr. Waddell’s plant is nearer G. 
apocarpa than G. conferta , on account of ( inter alia) the papillose 
cells.”—H. N. Dixon. 
Amblystegium Kochii {?) near Perth, R.H.M. “ It is unfortunate 
that, as pointed out by Prof. Barker, two plants somewhat closely 
allied, are mixed in this specimen. The one, with denser, greener, 
slightly larger and less spreading leaves, is certainly a form of 
H. riparium , presenting little difficulty of determination, owing to 
the longer, characteristic cells. As to the other, after careful 
comparison of all my plants of A. varium, including the form 
known as var. orthocladum, and descriptions, I cannot believe that 
this plant belongs there. Apart from the habit (distant spreading 
leaves, &c.) the areolation is I think quite distinct. A. varium 
has always, I think, a very neat areolation, difficult to define, but 
depending partly on the short cells [2-4 times as long as wide 
(Limpricht) ; very rarely, if ever 5 times as long as wide (Cheney)] ; 
here the upper cells are rarely less than 3-4 times as long as wide, 
and often more than 5 times. The obscurity and irregularity give, 
too, a different look from those of A. varium. The short nerve, 
too, is an important argument against varium , although if it were 
by itself, it would not be conclusive The Cherrybank plant (and 
an identical one almost, which I have gathered in Northants) 
agrees I think T may say exactly with Mitten’s A. Juratzkanum, 
Poynings, Sussex, 1895, in leaf characters—not in habit, and, if 
that plant be correctly named, I should have no hesitation about 
identifying Mr. Meldrum’s plant with A. Juratzkanum. The limits 
•of that species are, however, very undefined at present. The tall, 
erect habit is distinct, but would not I think preclude its identifi¬ 
cation with A. Juratzkanum more than with A. varium. 
Since writing the above, I have turned to a specimen of Mitten’s 
of A. varium , which certainly has somewhat the habit of Mr. 
Meldrum’s plant, and the upper areolation quite as elongate ; the 
cell walls are firmer, however, the lower areolation showing the 
numerous basal, shortly rectangular cells with firm walls, character¬ 
istic of A. varium and the nerve percurrent.”—H. N. Dixon. 
Grimmia apocarpa. “ The colour of the peristome of G. apocarpa 
having been so often referred to, I may say that I notice the 
brilliant (purplish) red tint just before and just after the fall of the 
lid. This, however, begins to fade before long, and in two or 
three months has become a dull somewhat yellowish red. I thus 
expect to find the true colour only in specimens gathered soon 
after the fall of the lid.”—T. Barker. 
Dicranum scoparium var. orthophyllum , Towyn, page 135 in 1903 
Report. “ This should have been labelled D. Bonjeani. Mr. 
Ingham kindly drew my attention to the mistake.”—D. A. Jones.
