as wo were. The principal bushes in this i-e^ion are : Psychotria 

 rufipes, Tournefortia rufo-serieea, Urera alceaefolia, and some 

 others, the time spent in this region not being sufficient to make 

 as complete collections as was desirable. There are many ferna 

 and herbaceous plants in this region. Many of the herbaceous 

 forms which occur here also occur lower down but are much 

 smaller in size. The most noteworthy of these are: Crotalaria 

 setifera and Fleurya aestuans, the last of which has fewer sting- 

 ing hairs than at the lower elevations where it occurs. Groves, 

 occur occasionally in the bushy areas, made up of the trees usu- 

 ally found in the moist regions. Some of these groves are quite 

 large, but usually they are small. Isolated trees are not at all 

 uncommon. 



No plants were collected above an elevation of 650 ft. on thi& 

 side of the island, but other members of the party who succeeded 

 in getting farther inland, report that there is a decrease in the 

 number of vines and an increase in the size of the bushes higher 

 up. Messrs. Williams, Ochsner, and Gifford succeeded in reach- 

 ing an elevation of 1,100 ft. here, reported that the country, a 

 short distance beyond where ther discontinued their journey, ap- 

 peared to be covered with low spreading trees or bushes on 

 which there was a large amount of ' ' brown moss. ' ' A large part 

 of the country, above the Scalesia forests, and bush areas, had a 

 distinctly brown color in which there are patches of green. The 

 brown color is possibly due to a heavy growth of one or several 

 species of leafy Hepatics, and is confined to the south side of the 

 island, none of it appearing on the other sides. The top of the 

 mountain is covered with green vegetation, but it is likely that 

 there are no trees present there, because none appeared in the 

 sky-line when the top of the mountain was viewed with a field 

 glass on a clear day. 



As near as could be ascertained, the dry region extends to an 

 elevation of about 350 ft., the transition region to 500 ft. while it 

 is likely that the moist region extends to at least 1,500 ft. and 

 possibly higher. 



Judging from the appearance, the upper part of this island 

 ought to be very interesting botanically, as it is apparently en- 

 tirely different from the upper part of any other island visited. 



It would probably require a week or more to explore this re- 

 gion properly, and in order to do this, it would be necessary to 

 out a good trail into the interior, and a camp established, where
