Observations made in the southern part of this area, the desert 

 belt or "Namib". The western fringe is occupied by lofty sand-dunes 

 with a scanty Vegetation including Acanthosicyos horrida, Tamarix 

 articulata and a few others. Rast of the sand-dunes on a harder 

 surface, there is a richer flora consisting chiefly of deep-rooted 

 Woody perennials of low habit and with small leaves. Welwitschia 

 is abundant on the Namibplateau and descends the ravines leading 

 down to the deeper river Channels. Pollination is effected mainly 

 by Odontopus sexpunctulatus (Hemiptera). Abundant fertile seeds 

 are produced but no germinating seeds or seedlings were found. 



The Namib flora is in the author's opinion of great age, and 

 the climatic conditions at present prevailing in South -west Africa 

 have been permanent for a long period. The flora is probably deri- 

 ved from the same stock as the Acacia formation flourishing to 

 the east. W. G. Smith.

This handbook of the flowering plants and ferns of the Central 

 and northeastern United States and adjacent Canada differs 

 from the earlier issues of the well known "Manual" of Asa Gray, 

 including the posthumous sixth edition prepared by Watson and 

 Coulter, primarily in a rearrangement of the families into the new 

 almost universally used sequence of Engler and Prantl, in a 

 revision of nomenclature in accord with the rules of the Vienna 

 Congress of 1905, and in the provision of numerous thumb-nail 

 illustrations in the text by which many technical characters are 

 more directly presented than they are conveyed by words. Form the 

 sixth edition is further differs in the Omission of plants found only 

 west of the 96^^ meridian and in the inclusion of those found in 

 the Eastern Canadian provinces. Though conservative , its authors 

 have included a large number of the recent species-segregates, and 

 they conveniently indicate the New-American synonymy when dif- 

 ferent from that adopted. As with earlier editions, the aid of speci- 

 alists has been sought in a few difiicult groups. 



As now limited geographically, the Flora is a fairly natural
