THE JOURNAL OF BOTANY 
it attempts to summarise various modern aspects of plant pathology 
and contains much information which has not previously appeared as 
text-book matter. The author regards Plant Pathology as a separate 
study, but holds the view that a plant pathologist must not only be 
a specialist but a general biologist as well: it begins to be a generally 
expressed opinion that health and disease in plants is an extremely com¬ 
plicated affair—plants are very human. The book is divided into four 
portions—Recognition of Plant Diseases, Knowledge of Plant Diseases, 
Origin of Plant Diseases, and Plant Protection ; forty pages or so of 
the third part which deal with fungus and insect parasites seem out 
of place in a book of this type. It is a common failing of elementary 
books to give long lists of what are practically only bare names of 
fungi; these are more misleading than useful when there is not suffi¬ 
cient detail nor illustration. The book would prove an excellent one 
for practice in translation from the German, as the subject-matter is 
clear, concise, and up-to-date.—J. R. 
The Children's Booh: of Knoivledge, which Messrs. Cassell are 
publishing in monthly parts, is attractively produced, but the botany, 
judging from the article on the Lily in no. 28, would be better 
for revision. “ The lily,” we are told, “ is the sign of the Resurrec¬ 
tion, and as such is the Easter flower .... [It] was long used as 
the Easter lily, but since its flowers often failed to appear in time for 
Easter, its place has been largely taken by the Bermuda lily ” ; no 
tradition, however, connects Lilium candidum with Easter, and the 
second sentence quoted shows that it could not be so associated. One 
can hardly allow that the Liliacece are “ one of the most important 
orders of plants, since so many of its members including asparagus, 
onion, leek, garlic, chives, etc. are articles of food”; but the most 
remarkable feature of the article is the introduction of a beautiful 
figure of Nymphcea stellata, with the legend:—“ The Starred Water- 
lily, a lovely example of this interesting group ”! 
The Orchid Beview for September contains an interesting paper 
by Colonel Godfery on the plants which in this Journal for 1921 
(p. 106) he named Epipactis Muelleri , separating it from E. viri- 
diflora Reich, with which it had been confused, and expressing a 
doubt based on his very full investigation and description ( l . c.) as 
to whether it did not constitute a distinct genus. This view has been 
adopted by W. Zimmerman, who has published it as Barapactis 
epipactoides. The specific name obviously cannot stand in view of 
the identity of the plant with E. Muelleri , but we leave to amateurs 
of “ new combinations,” or, better, to workers at Orchids, the making 
of the necessary alteration. 
Hitherto the mathematical, physical, and biological papers sub¬ 
mitted to the Cambridge Philosophical Society have been published 
in one series of Proceedings. In order to facilitate the publication 
of the results of biological research carried out in Cambridge, it has 
been decided to attempt the publication of a separate series of Bio-
