A low sand and mangrove islet, substantially circular in form, 

 about three quarters of a mile in diameter and rising barely two feet 

 above the sea at its highest point. The eastern part is devoted 

 entirely to a colony of Rhizophora mangle a small sand beach on the 

 west being the only dry land in the mass. This bit of strand has an 

 immediate sea border of Cenchrus tribuloides backed by a Eustachys- 

 Borrichia-Hymenocallis association with which a few patches of Cyperus 

 brunneus are mingled. Upon the area between this higher land and 

 the mud flat near the mangroves is a mixture of various species with- 

 out definite association character; the low, muddy flat between this 

 and the mangroves yields the usual Salicornia-Batis-Monanthochloe- 

 Sesuviutn association of the key salinas; while bordering the mangroves 

 themselves is the typical scattering of Laguncularia and Avicennia. 



The large number of diverse species on so small a bit of land indi- 

 cate it to be a favorite resting place of aquatic birds.
