ANNOTATED LIST OF MARINE PLANTS 

 OF LAMESHDR BAY, ST. JOHN, AND VICINITY 



The marine plants of the Virgin Islands were studied in detail by 

 the Danish botanist, F, Borgesen, who visited the islands in 1892, 

 1895-96, and 1905-06, and published numerous papers based on his 

 collections. Most significant is, "The Marine Algae of the Danish 

 West Indies," issued in parts from 1913 to 1920, in which 327 

 species of algae (90 Chlorophyta, 45 Phaeophyta, and 192 Rhodophyta) 

 were obtained, including many new species. Dr. Harold Humm is 

 continuing systematic studies on the marine plants of this area. 

 During the present study, 153 species of plants were obtained (54 

 Chlorophyta, 26 Phaeophyta, 70 Rhodophyta, and 3 Spermatophyta) 

 including 26 species newly recorded for the Virgin Islands. 



The following list summarizes known depth distribution, consumers, 

 and habitat notes: 



CHLOROPHYTA. Green algae. 



*Acetabularia pusilla (Howe) Collins . Found twice on S trombus 

 shells on the algal plain in 20 m depth. Known from 

 Florida, the Bahamas and Jamaica, but reported here for 

 the first time from the Virgin Islands. 



Acicularia schenckii (Mobius) Solms-Laubach. Locally common 



on the algal plain in 15 to 31 m depth, but most conspicuous 

 in open areas of fine shell attached to shell fragments or 

 small rocks. Reported by Taylor (1960) to 73 m depth. 



Anadyomene stellata (Wulfen) C. Agardh. Common on the algal plain, 

 occasional on the reef and in sea grass beds, often epiphytic, 

 particularly on Avrainvillea and Digenia , but also attached to 

 rock or forming loose, unattached masses. Found in 3 to 24 m 

 depth. During feeding trials, no fishes were seen eating 

 Anadyomene , but samples usually disappeared, apparently eaten, 

 within 48 hours . 



*New record for the Virgin Islands, 



VI-177
