time, not only in P. alpinum, but in other species of the genus, and has led in 
one case at least, in South Africa, to the erroneous record of Dendroligotrichum 
as occurring there. 
Climacium dendroides (L.) Web. & Mohr. — Bear Id.; 17 June, V. S. Sum- 
merhayes (4b). Berggren records a single stem only, from King's Bay. 
Thuidium abietinum (L.) B. & S. — One or two gatherings were made of 
this. Berggren records it only from Green Harbour and Advent Bay. 
Amhlystegium serpens (L.) B. & S. — Bear Id.; 17 June, V. S. Summerhayes 
(79). Sterile: not previously recorded from Spitzbergen. 
Calliergon sarmentosum var. f ontinaloides Berggren. ^ — Cape Boheman; 15 
July, V. S. Summerhayes (iioa). The exact habitat of this remarkable form is 
not given, but I have no doubt it was a submerged form. It appears to conform 
very fairly with Berggren 's description of his var. f ontinaloides (of which I have 
seen no specimens)'^ from the Dovre, Norway, but is, I should judge, a still more 
extreme form. The stems are 15 cm. long, very closely and regularly pinnate with 
short, subequal, widely divergent, elongate, much attenuated leaves. The 
plant has, in fact, in almost every particular (except that the leaves are straight, 
not falcate) the appearance of a Drepanocladus such as D. Rotae, and it is 
hard to convince oneself, even when examining it with the lens, that it is not 
that, but a Calliergon. The lower part of the stem and the lower branches are 
much denuded, which appears to indicate a station in flowing water. 
The variety has only been recorded from the high alps of Styria in addition 
to the original locality. I have a somewhat similar form from New Zealand, 
collected by Dr. L. Cockayne "on bottom of shallow natural pond in Craigieburn 
Mts., Canterbury, at 1200 m. alt. "

ON SOME MOSSES FROM THE BLUE MOUNTAIN OF CUBA 
Elizabeth G. Britton 
On April loth, 1922 Mr. George Conrad Bucher spent the day on the summit 
of the highest peak of Cuba, Pico Turquino, 7600 feet and collected six mosses 
which are interesting because of their rarity and identity with those from the 
Blue Mountains of Jamaica, occurring on Sir John Peak and Blue Mountain 
Peak, at altitudes ranging from 5000 to 7400 feet, and including three new 
records for Cuba. 
Holomitrium calycinum (Sw.) Mitt. 
Type locality: Jamaica, widely distributed at elevation of 5000-7420 feet, 
usually on tree trunks. Recently collected by Pre. Clement in the Sierra Maestra. 
No. 28, Bucher. 
Campylopus Brittonae R. S. W. Second West Indian record! 
Type locality: Summit of Sir John Peak, Jamaica. 
2 Since the above was in print Mr. Chamberlain has kindly sent me a specimen of the Nor- 
wegian plant, leg. Bryhn et Hogen, which quite confirms the original determination. The Spitz- 
bergen plant is a somewhat more extreme form.
