Corchorus hirsutus L., Helicteres jamaicensis Jacq, and Cro^on-species, 

 proving how dry and hot the locality is. 



More landwards the vegetation becomes higher and gradually 

 takes the appearance of a xerophilous copse-wood, formed by small 

 trees and bigger bushes (fig. 27). Among the most characteristic 

 species we meet here Erithalis fruticosa L. a little tree at 

 about the height of a man or more, richly ramified, with a 

 very characteristic appearance on account of its leaves which like 

 rosettes are placed at the top of the branches. The leaves are 

 broadly obovate, with decurrent margins, they are leathery and 

 rather thick and shining. The anatomy of the leaf is mentioned 

 by Warming (1. c. p. 234). Tecoma leucoxylon L. which makes 

 its home in dry copses is also common. Coccoloha uvifera (L.) 

 Jacq. is now larger and sometimes occurs as a rather tall bush, 

 but even here at a rather great distance from the sea it is often 

 decumbent and low, as seen in the front of the picture. Manchineel 

 occurs only rarely or is sometimes altogether wanting. Moreover 

 Chrysohalanus Icaco L. occurs in these copses ; it is a smaller tree 

 or large bush with broadly obovate leaves sparsely-placed upwards 

 on the branches, and several others. As one gradually leaves the 

 coast, the vegetation passes more and more into common copse- 

 wood, as the halophytic plants are gradually replaced by inland 

 plants from drier places. On the whole the vegetation seems to be 

 very xerophilous, and can therefore perhaps be compared with the 

 "Graa Klit" (gray dunes) occurring in our dunes ^). This dryness 

 is perhaps the reason why the Manchineel is almost wanting and 

 the Coccoloha so badly developed. 



As mentioned in the description of Krausse's lagoon this is on 

 the side turned towards the south-east separated from the sea by a 

 sometimes narrower sometimes broader sand-bank Avith sandy sea- 

 shore vegetation. Plate V shows a part of this vegetation' on a 

 projecting point. In the foreground some species of the Pes caprce 

 formation are seen, consisting especially of Sporobolus virginicus (L.) 

 Kth. and a few Ipomcea pes caprce L. Inside was found a luxuriant 

 vegetation rich in species consisting of the densely hairy, gray, thick- 

 leaved Touniefortia g naphalodes R. Br. here and there forming 

 close, low, compact growths, Suriana maritime L. a bush often
