Not known to occur east of the Cascade Mountains. The Wilkes Expedition specimens 

 (no. 3.59) undoubtedly belong to this species, but it is more than doubtful that they llilre 

 collected at old Fort Walla Walla (Wallula)^ 



The specimens referred by Hooker,o to Peucadanum foeniculaceum Nutt. very probably 

 belong to L. utriculatum. The Cooper specimens also referred to P. foeniculaceum b are 

 P. utriculatum.
