Illustrated Guide to British Mosses, with Keys to the Genera and Species. By H. G. 
Jameson, M.A., 8vo, pp. 80, 59 plates; 7s. 6d. Published by the Author, 
6, College Road, Eastbourne. 
This work supplies what has long been wanted, numerous accurate illustra¬ 
tions, fully up to date, arranged in accordance with Hobkirk’s Synopsis, 
published at a price that places it within the reach of all moss students. 
The “ Keys to the Genera and Species,” originally published in the “Journal of 
Botany” of 1891, are reproduced in a revised and more complete form, 
and the student who possesses this guide as a companion volume to Hobkirk’s 
Synopsis is in a most favourable position for the study of the British mosses. 
Following the Preface, in which the author gives the scope of the work, is the 
Introduction, which is arranged under seven headings, as follows :_(i.) The 
Moss Plant in general; (ii.) The Stem and its Appendages; (iii.) The 
Leaves; (iv.) The Capsule; (v.) The Spores; (vi.) The Inflorescence; (vii.) 
Practical Examination of Specimens, followed by a “ List of Contractions 
used in the Key.” All these paragraphs are carefully and lucidly written, 
and are illustrated by seven plates, containing fifty-nine figures, works 
of art, most wisely cbosen. Following this is the “ Key to the Genera,” 
similar in arrangement to that given by Bentham in his “ Handbook 
to the British Flora, and quite as helpful, which if carefullv used will 
enable the veriest tyro to find out to which genus any plant belongs ; 
and the student having successfully worked out his genera, will find in the 
“Keys to the Species” still further help to the identity of his plant. 
This is the first complete “ Key to the Species ” that has been pub¬ 
lished since the early days of Hooker and Taylor; each genus is prefaced by 
a few familiar remarks on its special features, and has a carefully-arranged 
“ Key to the British Species ” belonging to it, which is also illustrated by fifty- 
two plates, containing illustrations of every known British species. The 
illustrations are excellent, giving magnified representations, not only of the 
leaf, but also of the leaf apex and the leaf cells; and, as these are all drawn 
to one scale, the student is able at a glance to see both shape, size, margina- 
tion, and cell-form of the leaf, and to grasp with some ease the structural 
differences of closely allied plants. All who desire a better knowledge of 
our British mosses should at once procure the “ Illustrated Guide;” I can
