C. ciipressoides is a rather common species along the shores 

 of the Danish West Indies. 



Var. luamillosa is found at St. Croix on the south coast at Longford 

 and on the north side at Cane Bay. Var. typica, St. Croix: Christianssted, 

 Saltriver; St. Thomas: The lagoon at Bovoni. Ya.r. plumarioides, St. 

 Croix: The lagoons of Christianssted and Saltriver. YaLV. flabellata, St. 

 Thomas: West of Water Island in about 30m. St. Jan: off Christians- 

 fort in about 30 meters and in Lt. Maho Bay in about 20 meters. Var. ele- 

 gans, St. Jan: America Hill in about 30 meters and in Lt. Maho Bay in 

 about 20 meters.

A small dwarflike form. The rhizomes are often scarcely a 

 millimeter broad and downwards bear richly ramified rhizoids, 

 upwards few and scattered, often not a centimeter high shoots with 

 few and often rather irregularly shaped, sometimes cyhndrical 

 ramuli; only seldom has it normal ramuli swollen at the apex.

Before describing all the above-mentioned forms I may point 

 out that what I have said concerning C. ciipressoides holds good 

 here also, namely, that in my opinion it seems impossible to con- 

 sider all the above mentioned varieties as separate species; I quite 

 follow the views of M™*^ Weber-van Bosse. If one has a large 

 material it will soon be evident that the different forms are often 

 united to such a degree by transitions that the boundaries can only 

 be made quite arbitrarily. 



Thus, I believe that it is impossible to consider var. clavijera 

 and var. uvifera as separate species, as Svedelius tries to make 

 them, as these forms in my material are very evenly connected 

 with each other. As to this question referring for more detail
