260 ELEMENTS OF BOTANY. 
De Bary,** Comparative Anatomy of the Phanerogams and Ferns. 
Oxford, Clarendon Press, 1884. 
Bessey, Botany. Henry Holt & Co., New York, 1888. 
Thomé, Structural and Physiological Botany. John Wiley & Sons, 
New York, 1891. 
Sachs, Lectures on The Physiology of Plants. Macmillan & Co., 
Oxford, Clarendon Press, 1887. 
Gray’s Structural Botany is written in an exceedingly clear and 
readable style. It is not brought down to date and it gives little 
histology; it is well supplemented by De Bary’s work, and these two 
books, with the masterly lectures by Sachs, furnish a very full account 
of vegetable structure and life. Vines, Physiology of Plants, Cam- 
bridge, University Press, 1886, is more to be depended on in its 
chemical statements than the work of Sachs. Either Bessey’s or 
Thomé’s book furnishes a brief summary of anatomy and physiology. 
» Morphological. 
Goebel, Outlines of Classification and Special Morphology of Plants.** 
Oxford, Clarendon Press, 1887. 
Pax, Morphologie der Pflanzen.** Enke, Stuttgart, 1890. 
» Systematic. 
Warming and Potter, Handbook of Systematic Botany.** Mac- 
‘millan & Co., New York, 1895. 
Engler and Prantl, Die Natiirlichen Pflanzenfamilien.** Engel- 
mann, Leipzig. 
Le Maout and Decaisne, Traite Général de Botanique.** Firmin 
Didot Freres, Fils & Cie, Paris. 
Vines, Student’s Text-Book (see above). 
Strasburger, Noll, Schenk, and Schimper, Lehrbuch (see above). 
The first-named book in the list is clear, ably written, and 
sufficient for all ordinary purposes. Engler and Prantl’s work in 
several volumes is a very large and elaborate one, not yet completed, 
with a wealth of illustrations. Le Maout and Decaisne’s treatise is 
not modern, but is abundantly illustrated and will be found useful.
