BOTANICAL BOOKS AND THEIR USE 129 



"Climbing Plants," contain much ecology, and two of 

 the most recent text-books, those by Barnes and by 

 Atkinson, contain sections specially devoted to it. 



For microscopic anatomy there is one very excellent 

 work, full of the most practical and the most scientific 

 information, Strasburger's " Das botanische Practicum," 

 of which there is a condensation called " Das kleine 

 botanische Practicum," translated by Hillhouse, under 

 the title " Practical Botany." By aid of this book 

 one could, without a teacher, work through a valuable 

 course in plant anatomy ; and it would be a great 

 advantage if there were similar works for other phases 

 of the science. On the ecological phases of the 

 minute anatomy of plants the great work is Haber- 

 landt's " Physiologische Pflanzenanatomie," a work that 

 is unfortunately not translated. De Bary's work, trans- 

 lated by Bower and Scott as " Comparative Anatomy 

 of the Vegetative Organs of Phanerogams and Ferns," 

 is a standard, of great fulness and authority. 



On the natural history of the groups of plants are sev- 

 eral excellent works, of which the greatest is Engler and 

 Prantl's "Die natiirlichen Pflanzenfamilien," in German, 

 of which twelve volumes have appeared with three or 

 four to follow, profusely illustrated and most authorita- 

 tive. Goebel's work, translated as " Outlines of Special 

 Morphology and Classification," is very valuable, but 

 needs revision. More recent is Warming's excellent 

 work, translated by Potter, under the title " Systematic
