nerve somewhat markedly papillose. The leaf form, however, and the dis- 
tinctive basal areolation, are quite characteristic of G. commutata, and I think 
that it must be referred here. Mr. W. E. Nicholson concurs. The species has 
not been found in Spitzbergen before. 
Rhacomitrium canescens (Hedw.) Brid. — Prince Charles Foreland; 8 July, 
V. S. Summerhayes (67b). A striking form, with the stems almost simple, or 
once or twice divided, the short lateral branchlets being undeveloped. The var. 
ericdides — the exact antithesis of this — was collected, also on Prince Charles 
Foreland, by Mr. C. S. Elton (Z4;. 
Orthotrichum rupestre Schleich. — Rock in Eriophorum Moss, Bruce City; 
J. Walton (L). Not hitherto on record for Spitzbergen. 
Bryum glohosum Lindb. — Bear Id.; 13-23 June, V. S. Summerhayes (6b), 
with one or two old capsules : Bruce City ; 19-20 July, V. S. Summerhayes (124b), 
with abundant capsules, both the somewhat immature, operculate capsules of 
the present year and the old capsules of the preceeding season, in, however, 
fairly good condition, with the peristome nearly intact. The globose, inflated 
capsules, of thin texture, agree exactly with Lindberg's specimens in our National 
collections, and in the fres'h state, and in their dense profusion, made an object 
of great beauty; which, alas! disappeared to a great extent in drying. 
Var. ruberrimum Dixon, var. nov. — Tundra, Klaas Billen Bay; 5 Aug., C. S. 
Elton (K23). Theca pulcherrime rosea. Lindberg describes the capsules of 
B. glohosum as "pallide vinosa," but the reddish color must be very faint; in 
his specimens at Kew and the British Museum I do not find any trace of red; 
as in Nos. 6d and 124b, above, they are a pale brown. This applies both to the 
somewhat immature capsules of Mr. Summerhayes, gathering and to the mature 
deoperculate ones. In the present plant the capsules are of equal abundance, 
and of precisely the same form and character, but are of a very bright rosy red, 
and even in the dry state make an extremely striking object. Arnell speaks 
of the type of B. glohosum as being the greatest ornament of the Arctic zone, 
but it is certainly far surpassed by this very beautiful variety: — "matris pulchrae 
filia pulchrior. " 
Cinclidium stygium Sw. — Gips Valleys; 26 June, V. S. Summerhayes (3oe), 
sterile. Berggren records only C. arcticum B. & S., but the present plant cannot 
be that, as the cells are distinctly in divergent rows. 
Meesia triquetra (L.) Aongstr. — In several localities. Limpricht (Laubm. 
p. 515) describes the leaves as "ganzrandig, nur bei den Varietaten rings gesagt. " 
This seems to be a rather remarkable statement. I do not remember to have seen 
a form with entire leaves. The leaves are described as toothed by all the authors 
I know, and are so figured in the Bryologia europaea. 
Philonotis tomentella Mol. — Sassen Valley; 17 July, V. S. Summerhayes 
(iiSa). Not hitherto recorded from Spitzbergen, but doubtless included in the 
forms recorded by Berggren as P. fontana Brid. 
Polytrichum alpinum L. — A form from Prince Charles Foreland, V. S. 
Summerhayes (57 o) has the stems divided at the apex into numerous short, 
crowded branches, so as to be quite dendroid. This form occurs from time to
