— In an article entitled "Two Hitherto Confused Species of 

 Lycopodium " in the Bulletin of the Torrey Botanical Club for 

 November, F. E. Lloyd presents some additional evidence to 

 prove that what has been regarded as the variety Chamcecyparissus 

 of Lycopodium complanatum is entitled to specific rank. The 

 principal points in which Chamacyparissus differs from com- 

 planatum is shown to include the subterranean rootstock, the 

 more erect branches producing annual growths at the end of 

 the branchlets, the less flattened distal branches, and the ripening 

 of spores a month or more in advance of the other. L. Chama- 

 cyparissus has been regarded as distinct by many botanists, the 

 first to note it being Alexander Braun, whose name now stands 

 as the authority for the species. 



BOOK NEWS 



Upon examing the new book by Doctors Rusby and Jelliffe. 

 on the "Morphology and Histology of Plants, "f one is at a loss 

 which most to admire, its comprehensiveness or the style in which 

 it is written. The book is issued in place of the authors' earlier 

 volume. " Elements of Pharmacognosy," but it is in reality a new 

 work, being entirely revised and much new matter added, the 

 latter principally chapters on collecting and pressing specimens, 

 the dissecting and analysis of flowers, and kindred topics. The 

 authors' success in their respective branches is sufficient guar- 

 antee that the book contains the proper matter for the embryo 

 pharmacist, and we may therefore judge the book upon its 

 usefulness to the general botanist. After a surfeit of books, be- 

 ginning with the lower forms of plant life, it is refreshing to take 

 up one which at once breaks into a consideration of the flower — 

 the part of botany that is most attractive to all beginners. The 

 chapters devoted to this part of the subject probably contain as 

 complete and scientific account of the flower and its parts and 

 the office each performs in the economy of the plant as it is pos- 

 sible to find. The discussion then proceeds to the seeds, roots, 

 stems and leaves. Each paragraph is introduced by the title of 

 the topic treated therein which will greatly facilitate reference to 

 the work. Since powdered drugs for the most part engage the 

 attention of the pharmacist, the section devoted to histology will
