This is, according to Schonibasiks a most beautiful tree, 
almost covered with bright yellow flowers, and is called by 
the natives Etabally, on account of its frequency at the cata- 
 racts of that name. It forms a genus of Bauhiniez; allied to- 
Schnella in its flowers; but very different in the foliage. I. 
have a second species, E. macrophylla, from the island of | 
St Vincent, which has blunt leaves 8 or 9 inches long, and : 
the impar very lax. |
