STEWART'S BOTANICAL SURVEY OF THE 

 GALAPAGOS ISLANDS* 



Mr. Stewart was the fortunate botanist appointed for this 

 special expedition to the Galapagos Islands. He gives a brief his- 

 tory of the Flora of the Islands dating from Darwin and Hooker 

 and follows with an account of the vascular plants annotated for 

 the publications where the species were first published, and for 

 the localities on the various islands of the group where the 

 numbered specimens were collected. Following this annotated 

 list he gives a series of tables showing the distribution of the 

 vascular plants, these tables presenting columns assigned respec- 

 tively to the different islands in which are marked the specimens, 

 or records of occurrence by previous authors. The species are 

 arranged in this list alphabetically, by genera, under each family, 

 the families are presented in the general sequence of Engler & 

 Prantl. Following the tables of distribution he presents a dis- 

 cussion of the botanical regions, distinguishing ecologically the 

 dry from the transition and these in turn from the moist and 

 grassy, etc., listing under each the commonest or most noticeable 

 during the time of the Expedition. 



Mr. Stewart then takes up in the order of families those in- 

 teresting plants, or those genera or even whole families which 

 present special points, as the number of species represented 

 in proportion to other families characteristic of this region, or 

 the citing of those which are conspicuous for the large and 

 pure stands, or for their distribution over large areas and notes 

 particularly that the Compositae are stronglj^ represented in the 

 moist regions, the chief representation of which are to be found 

 in the extensive forests of Scaesia. Following, he presents a 

 record of the weather conditions and the variety which these have 

 presented at various times and the effects of the different periods 

 of weather so far as indicated by the conditions of vegetation.
