The following species have been distinguished as found in tropical Polynesia, but the characters given 
for their separation do not seem to me, with the materials I have examined, to be sufficient for specific 
distinction :—1. A. evecta, Hoffm. 1. с. p. 29, from Society Islands (Forster!) and Tahiti (Соок! Banks !). 
Allied to A. evecta. 2. A. Durvilleana, De Vriese, Monogr. Maratt. p. 17, from Tahiti (Durville). 3. A.
