insect relations of this remarkable family. Heliamphora and Darlingtonia are 
still recognized as monotypic, but a new species of Sarracenia (S. Sledgei, from the 
Gulf states) is described, 7 in all being recognized.—J. 
Lactarius and Russula.—BatraiL_E® has published a monograph of these 
genera, to which he gives the group name Astérosporés, on account of their echinu- 
late or granulate spores. He describes all of the European species, adding personal 
observations to the diagnoses of the various authors. The keys are admirably 
constructed to lead easily to the species. For Lactarius the author has adopted 
the classification of QuéLET. For Russula the two grand divisions (Leucosporae 
and Xanthosporae) of QuUELET are continued, but a number of subsections are 
defined and named. At the same time, it is shown, that the color of the spores is 
not a very reliable character, and the principal groups must be defined by a varying 
combination of characters.—J. M. C. 
Grout’s Mosses.—The fourth part of this work,'® issued in April last, main- 
tains the reputation of its predecessors and brings the author’s task within sight 
of completion. Part V, the final one, is announced for 1909, to contain some 
plates and text missing from this part, together with an index and other useful 
adjuncts. 
Part IV completes the Leskeaceae and contains a good part of the Hypnaceae, 
with the usual excellent reproductions of illustrations from the Bryologia Europaea 
and SuLLivant’s Icones, and some characteristic details which are original.—

Index of desmids.—A supplement to NorpstEepr’s Index Desmidiacearum, 
which was published in 1896, has just appeared.*' The interval of over ten 
years has witnessed such an accumulation of material that a large supplement 
became necessary. The new bibliography included bears testimony to the great 
activity of the students of the group during this period, about 500 titles being 
enumerated, under 120 authors. To examine this vast amount of material and 
to organize it for the purpose of the index has called for an amount of labor that 
the students of desmids are sure to appreciate.—J. M
