NO. 2 GENTRY : LAND PLANTS 79 



Maria Gleofa Island. The last and southern-most of the group is 

 Maria Cleofa. In dimensions this island is approximately 6 kilometers 

 long, 5 kilometers wide with an area of about 25 square kilometers. The 

 one central peak is given as 402 meters in elevation. 



Except for the brief remarks of Grayson and Nelson, the only 

 naturalists who have visited the island, there is little known of the 

 island. Nelson noted that canyons descend from the central peak in all 

 directions. At least one of them carries an intermittent stream, which 

 sinks in its bed before reaching the sea during the dry season. In com- 

 parison to the other islands Nelson states (1899:12), *'Maria Cleofa 

 is more rocky and sterile, and the trees are bushy and stunted." 



The total known flora of land plants consists of Nelson's collection 

 of these four species: Zamia loddigesii (?), Arundo donax, Cyperus 

 ligularisy and Trixis Wrightii,
