Between Monterey 



and Cerralvo, Wislizenus gathered a fruiting specimen (No. 343), with mature dehis- 

 cent pods, which is most likely a variety of A. tephroloba. These pods are broader 

 and proportionally shorter (oblong, an inch wide, and 3 or 4 inches long), somewhat 

 curved. the valves more indurated, and the lar^e seeds flat.

But I 



fear it is much too near A. Texensis (of which I have no authentic specimen), and 

 I am confident that it passes into A. hirta.
