any contraction, making it very difficult to conceive that the two can belong to one species ; but in other 

 specimens even these characters are variable; sometimes the same pod is moniliform in a portion of its length, 

 continuous in the remainder ; and the flat pods (as in Prosopisjuliflora) appear to be the \inripe state, or 

 sometimes an imperfectly developed although ripe state. Many specimens arc also, as. usual, without 

 any pod ; and I have been quite unable, in that state, to sort them into distinct varieties. 



Mimosa indica, Poir. Diet. Suppl. 1. 80, from a specimen in the Munich herbarium, from the Jardin {\v^ 

 Plantes of Paris, appears to be the A. macracantha ; but the flowers and fruit being unknown, it must at 

 any rate be erased from the list of species.
