Humaria pilifera Sacc. New to Yorks. This very beauti- 
ful species was found by Messrs. Wager and Peck. It is a 
small orange-red discomycete occurring on sandy soil. The 
margin and exterior of the ascophore are minutely fimbriate. 
The clavate paraphyses are remarkably beautiful, being filled 
with orange oil globules at the apex, these giving the character- 
istic colouration to the disc. 
Mr. Clarke subsequently circulated to members from his 
portfolios, drawings and notes on Cordyceps capitata made 
respectively by Bolton (1786) and Sowerby (1803).

Wonders of Wild Nature. By Richard Kearton, F.Z.S. Cassell & 
Co., Ltd., 1915, 174 pages, 6s. The house of Cassell has issued a number of, 
volumes under the name of Kearton, and these have usually been exceed- 
ingly attractive from the fact that they have been well illustrated. The 
present volume contains photographs taken by Richard Kearton and his 
daughter Grace. It includes chapters on ‘ Wild Life Round London,’ 
‘ Wild Life of Lonely Isles,’ ‘ Bird Life on the Polders and Meers of Holland,’ 
and ‘ Wild Life on the Norwegian Mountains.’ Many of the photographs 
are of great interest and there are some illustrations in colours. It is a 
very attractive volume. 
Whitby Wild Flowers. By Bernard Reynolds. Whitby: Horne & 
Son, 1915, pp. 60, ts. net. This list of Whitby plants is intended to replace 
that by J. Swales in the ‘ Guide to Whitby.’ It is much fuller and better 
than most lists in guide books, and includes not only the district of Whitby, 
but also Levisham and Scarborough. ‘The Latin names we are told are 
those of Babington’s Manual, oth edition, but unlike the latter work, the 
author is very erratic in his use of capitals for specific names. More than 
half the book is devoted to notes on the plants, and these add greatly to 
the value and interest of the work. In this section are contributions by 
Mr. F. Arnold Lees, Rev. E. A. Woodruffe Peacock and Mr. J. Foggitt. 
The localities of the more interesting species are described in accounts of 
six excursions, in one of which a reference to Cyprepedium requires con- 
siderable revision. The work concludes with ‘ Floral Notes’ extracted 
from the contributions of the late John Swales. In a short bibliography 
a list is given of some of the chief Yorkshire floras, in which the author 
misquotes and apparently misunderstands Davis & Lees ’ West Yorkshire. 
The Families of British Flowering Plants. By W. B. Grove, M.A. 
Longmans, pp. vi. + 49. 1Is.net. This little work reminds us, were that 
necessary, that the ‘old order changeth.’ The system of Bentham and 
Hooker, which has so long served British botanists, is slowly but surely 
giving place to the more natural system of Engler. This is the natural 
result of scientific progress, and the time now seems ripe for the change, 
though doubtless many present-day botanists will still cling to the more 
familiar system. The families, i.e., the natural orders of British floras, 
are arranged on Engler’s system, with several slight modifications, and the 
author adopts from Moss’s British Flora the group names Amentiflorae, 
Petaloideae, Centrospermal and Heterochlamydeae. The characters of 
each family are in most cases fully given, together with a list of British 
genera, and also the more interesting foreign genera which students should 
be familiar with, or are met with frequently in cultivation. The synopsis 
is well arranged and clearly printed, though some of the contractions are 
at first a little puzzling. It will form a handy guide to students working 
at systematic botany, and doubtless will become of general use in the 
determination of the main groups of flowering plants.
