occasionally mixed with sand forming an even transition to the 

 sandy shore, or it becomes still more firm and dry, passing evenly 

 to the dry soil which further inland gives place to the xerophilous 

 copses. The Conocarpus formation has simply to be regarded as 

 a transitional formation from the mangrove to the sandy shore 

 vegetation, and partly too to the inland vegetation. 



Besides Conocarpus erecta L., which is a small tree, or more 

 often only a bush (fig. 21), I may refer to this formation of charac-

teristic plants Anona palustris L. (fig. 22), which is also a larger 

 bush, and Bucida Buceras L., which can be an even rather tall 

 tree. Further, the stout fern Acrostichum aureiim L. must be classed 

 with this formation. 



Conocarpus erecta L. often occurs on damp soil, but it is also 

 to be found on even rather dry soil as well as on sandy or rocky 

 substratum. Thus it was found as low scattered bushes on a dry 

 Sporobulus-grass plain on the innermost side of Krausse's lagoon, form- 

 ing here a Conocarpus association (fig, 21). On page 223 I have given a
