simply serves to illustrate the great amount of information that can be 
obtained from a table which seems to be packed with details. We com- 
mend this book to all botanists interested in the subject, as one which 
will give them a vast amount of accurate adap upon a subject 
whose literature is widely scattered or hard to obta 
A Monograph of the Lotus. 
Dennert, who completed and edited this posthumous monograph,’ 
tells us that Wigand was well known to be an energetic adherent and de- 
fender of the dcctrine of the fixity of species. He hoped to secure, through 
the work of his students and others, a series of exhaustive monographs, not 
only of families and genera, but also of species, in which every character 
of the plant should be set forth. From such a series of works upon 
nearly related plants, he hoped to be able to draw important conclusions 
regarding the value of specific characters, the relations of variation, and 
particularly to obtain an exact definition of the term “species.” As an 
indication of the sort of work which he wished, he undertook this mono- 
a most interesting plant, the famed Lotus. But the work was 
interrupted and left incomplete at the author’s death, and Dr. Dennert, 
assistant in the botanical institute at Marburg, added the anatomy of the 
nodes, the leaf blade and its origin from the eet etc. The paper dis- 
cusses the morphology, development and anatomy of every part of the 
plant, and concludes with biological remarks on the starch in the leaves 
and rhizome, and on the vegetative and resting conditions of the rhizome. 
From this it will be seen how wide is the scope of the monograph. Its 
execution is admirable and the paper may well be taken as the model it 
was intended to be. This is the exhaustive style of work to which 
we have eens American botanists.

THE INSECT RELATIONS of oo. receives a fresh contribution from 
Mr. L. H. Pammel, who writes of the pollination of Phlomis tuberosa, an 
the perforation of flowers by insects? Phlomis tuberosa is compared 
with P. Russeliana, of whose pollination an account is given by Loew, and 
which it much resembles. On the e perforation of flowers Mr. Pammel has 
collected much widely scattered literature, both on the direct subject and 
several related ones. The paper is ‘accompanied by a very full biblio- 
graphy, and will certainly be of much service to students in this field.
