SUMMARY OF CURRENT RESEARCHES RELATING TO 
pointed leaves, its elongate cells papillose nearly throughout, and by its 
small capsule subglobose when dry. Discovered first in Trinidad in 
1903, it has now been found to occur also at the Kaieteur Falls. A. G. 
Note on a Moss in Amber. — H. N. Dixon ( Journ . of Bot., 1922, 
60, 149-51, fig.) A description of a well-preserved fragment of 
Hypnodendron in a piece of amber from Lower Miocene beds in Upper 
Burmah. Other pieces of amber contain insects. Judging from the 
leaf structure, the moss might be H. Rein war dtii or H. arborescens. 
Trustworthy records of fossil mosses are scanty — an Andreaea from the 
Devonian in Norway, Rhynchostegium and Glyphom itrium from the 
Tertiary, in North America, a few from Baltic amber, and from Tertiary 
deposits in Europe ; and a Mnium from the Lower Pliocene. A. G. 
New Variety of Orthodontium gracile Schwaegr. — W. Watson 
{Journ. of Bot., 1922, 60, 139-41, fig.). An account of a remark- 
able form of this moss found in September 1920 on the millstone on 
the borders of Cheshire and Yorkshire at an altitude of 1700 to 1800 feet. 
It is described as var. heterocarpa , and differs from the type in having 
a shorter, broader, often more or less gibbous capsule, smooth or sulcate, 
straight or curved ; inner peristome teeth minutely punctate ; leaves 
shorter and less flexuose. It is a puzzling plant which might be passed 
as a Dicranella. A. G. 
Mosses of the English Lake District. — C. H. Binstead {The 
Vasculum , Newcastle, 1922, 8, 65-83). An enumeration of all the 
mosses hitherto recorded for the Lake District, together with their 
distribution and frequency, and containing a total of 368 species and 
numerous varieties. Much active collecting was done in Westmorland 
during last century by G. Stabler and J. M. Barnes. Further research 
is needed in Cumberland. A. G. 
Moss Exchange Club. — {Twenty -seventh Annual Report, June 
1922. Arbroath: T. Buncle, 284-98). Contains lists of Sphagnacese, 
mosses and hepatics collected and contributed by the members of the 
club, with critical notes on some of the specimens. Corrections are also 
given of some of the published records for the counties of Worcester, 
Stafford, Warwick and Hereford. A. G. 
Moss Records from St. Kilda. — William Evans {Trans. Bot. Soc. 
Edinburgh, 1921, 28, 67-9). A list of thirty-two mosses from the 
remote island of St. Kilda, the moss-flora of which was almost unknown. 
There is a tendency to departure from type in several of the species, 
and fruit is rarely produced. Lying out in the Atlantic, some 40 miles 
west of Harris, it has a remarkable avi-fauna. A. G. 
Sphagnum as a Surgical Dressing. — John W. Hotson ( North - 
west Division of the American Red Cross , 1918, 31 pp. 18 figs.). An 
account of the structure of Sphagnum, its distribution in America, the 
species best suited for dressings, their remarkable absorbency (up to 
twenty times their dry weight), the work of the British organizations, 
the movement in America, the proper way to collect and sort the 
material, and the improved American dressing with non-absorbent 
backs. A. G.
