scenes. The illustrations are usually well executed and will prove of great 

 value in botanical classes. 



The vegetation of east Africa, so long poorly known, but now so fully 

 brought to light by the work of Dr. Engler and his associates, is presented 

 yet more clearly by an excellent series of 64. reproductions from photo- 



r 



i graphs, taken by Walther Goetze, who lost his life while engaged in this 



I work.-* Among the views here presented are coastal steppes, high grass 



steppes, Acacia and other tree steppes, palm woods, Euphorbia thickets, 

 alluvial forests, mountain woods and thickets, mountain meadows, rainy 

 forests, etc. Good text descriptions accompany the views, and it is safe to 

 say that one may get from a careful study of this work a vivid and true pic- 

 ture of many of the plant formations of German East Africa. — H. C,

MINOR NOTICES, 



A. J. McClatchie^ has brought together a large amount of interesting 



information concerning Eucalyptus. The purpose of the bulletin is to give 

 information concerning the characteristics of the "eucalypts," their climatic 

 requirements, and their uses ; to give directions and suggestions as to their 

 propagation and culture; and to furnish a means of identifying seedlings 

 and mature trees. It seems that these trees now serve very many useful 

 purposes in the Southwest, and give promise of great future usefulness in 

 the semi-arid portions of our continent- The covering of the now untillable 

 treeless portions of the semi-tropic section of America with such trees as 

 eucalypts, which will yield fuel, timber, and other useful products, and also 

 furnish protection from the sun, from winds, and from floods, or otherwise 

 ameliorate existing climatic conditions, is certainly an achievement greatly 

 to be desired. The characteristics of forty-one species, being the principal 

 ones grown in America, are discussed, and illustrated by the ninety-one 

 handsome reproductions of photographs. — J. M. C. 



HiLDEBRAND* has published under the title Achtilichkeiteji im Pflan- 

 zenreich, a volume rather out of the ordinary in the nature of its contents. 

 The material presented is familiar to botanists, and yet would not particu- 

 larly attract the popular reader. The stock cases of similarity in general 

 habit, and in various organs (such as cacti and euphorbias, leaves and ph}'llo- 

 clades, raspberries and mulberries, chestnuts and horse chestnuts) are mar-
