tion on the west side is from 200 to 800 m., and on the east from 

 1 to 800 m. 



II. The Plain of Sharon or Maritime Plain, including the 

 lowland, except the sea coast from Mt. Carmel to Beersheba, with 

 an elevation of 1 to 250 m. 



III. Maritime or actual sea coast, 1 km. wide, from Tyre to 

 Gaza, having an elevation of 1 to 15 m. 



IV. Northern Palestine includes Samaria and Galilee from 

 Nablus to the foot of Mt. Hermon and the Litany river, and is 

 bounded on the east by that portion of the Jordan river above sea 

 level, and on the west north of Mt. Carmel by the Maritime 

 district. Its elevation is from 1 to 1200 m. 



V. The Jordan Valley comprises the country below the level 

 of the Mediterranean Sea from Lake Huleh to Jericho. 



VI. Gilead and the Hauran is the district east of the Jordan 

 between the Jabbok river and the foot of Mt. Hermon, with an 

 elevation of 1 m. to 1300 m. 



VII. Moab is the remainder of the East Jordan country, 

 1 m. to 1100 m. 



VIII. The Dead Sea is the most interesting district of all, con- 

 taining many strange and rare species, and including the land 

 around the Dead Sea, from Jericho (Wadi Kelt) to the south end 

 of the sea, with the valleys up to the level of the Mediterranean. 



The total number of species (excluding varieties), as given in 

 the Catalogue, is 2165, disposed in 735 genera and 120 families. 

 New species are continually being discovered, and a supplemental 

 leaf will be added to the Catalogue as occasion requires. 



A careful selection of the most useful synonyms is given, 

 especially of those given in other lists of Palestine plants but not 

 found in the Flora Orientalis of Boissier. Since, however, this is 

 indisputably the standard work for the botany of South-western 

 Asia, the arrangement of species follows the order of that work, 

 but the families and subfamilies are arranged according to 

 Engler's Syllabus, sixth edition. 



For this summary of the plan of the list we are mainly 

 indebted to a type-written Bulletin issued by the Botanical 

 Department of the American Colony in Jerusalem. The Cata- 

 logue cannot fail to be of interest for comparative purposes, and 

 its low price brings it within the reach of all. 



The Living Plant : a Description and Interpretation of its Func- 

 tions and Structure. By W. F. Ganong, Ph.D., Professor 

 of Botany in Smith College. 8vo, pp. xii. 478, tt. 178. 

 London : Constable. 1913. Price 15s. net. 



Dr. Ganong's book is not designed as a digest of our present 

 scientific knowledge of plant physiology for the use of experts in 

 that subject, but seeks to present to all who have interest to learn 

 an accurate and vivid conception of the principal things in plant life. 

 " I was once myself such a learner," the author remarks, " and I 

 have tried to write such a book as I would then have delighted to
