palustris does not seem to be very common on the Danish islands; 

 I have found it on St. Gioix at Saltriver, on St. Thomas at Bovoni 

 Lagoon and on St. Jan at the edge of the cultivated lagoon-like low- 

 land below "America Hill". 



Bucida Buceras L. is, as earlier mentioned, a larger tree which 

 likes damp soil near the outlets of the watercourses. 



We can further class with these species the large beauti- 

 ful fern Acrostichum aureum L., which seems to be distributed in 

 all tropical regions on a similar soil. It may be found in the 

 mangrove formation but seems most likely to belong to the Cono- 

 carpus formation, where it is found sometimes on damper, some- 

 times also on quite dry soil. 



Covering the ground where this formation grows Bacopa mon- 

 niera (L.) Webst. is found, which with its rooting branches is 

 creeping over the soft ground, further Heliotropium curassavi- 

 cum L. with bluish-green rather thick leaves, just as the little bush 

 Corchorus siliquosus L. is of frequent occurrence here; and Batis 

 maritima L. and several other saltbushes also occur, besides different 

 Gyperaceae, such as Cyperus elegans L. and C. ochraceus Vahl and 

 Gramineae e. g. Dactyloctenium aegi/ptium (L.) Willd., the above- 

 mentioned Sporobolus and several others, all species which are not 

 entirely characteristic of the Conocarpus formation alone but also 

 are more or less common to the other halophiious formations. And 

 in the same way several other species frequently and often in 

 great numbers join this formation, several of which are common, 

 and even have their proper home in the dry copses. This is e. g. 

 the case with the Acacia Farnesiana (L.) Willd. a species, which 

 Schimper also refers to the Nipa formation. It is a tall, thorny, 

 in the dry season leafless bush, which often covers wide areas of 

 old lagoon ground as a dense copse-wood. In this formation, espe- 

 cially on St. Thomas and St. Jan, Bromelia pinguin L. frequently 

 occurs in great numbers; and even plants so decidedly xerophilous 

 as Gactacese make their appearance (cfr. fig. 21). When the soil 

 begins to get more sandy, several species from the sandy shore 

 especially the splendid tree Terminalia Catappa L. imported from 

 Asia and sometimes too Cocos nucifera L. also appear. 



An area with such a vegetation is e. g. found at the head of 

 the large Nordside Bugt (Magens Bay) on the north side of St. 

 Thomas. On the rather damp, clayish, gray, somewhat sand- 

 mixed soil grows a luxuriant Acacia forest with numerous Bro-
