Sand Key, the smallest vegetated key in the group, is situated 

 about one and a half miles northeast of Garden Key. This little, 

 oval patch of sand, known to the natives as Hospital Key, is about 50 

 x8o feet, and has lost nearly the same area since it was charted by 

 the U. S. Hydrographic Survey. The central portion, which rises 

 about three feet above the sea and comprises fully one half the surface 

 of the islet, is occupied by a growth of Euphorbia buxifolia and Ipomoea 

 pes-caprae flanked on the eastern border by three separated patches of 

 Sesuvium portulacastrum, on the west by four shrubby plants of Iva 

 imbricata, and on the north by a clump of Uniola paniculata.
