Not known to.occur east of the Cascade Mountains. The Wilkes Expedition specimens 
(no, 359) undoubtedly belong to this species, but it is more than doubtful that they were 
collected at old Fort Walla Walla (Wallula). 
The specimens referred by Hooker,a to Peucadanum foeniculaceum Nutt. very probably 
belong to L. utriculatum. The Cooper specimens also referred to P. foeniculaceum © are 
P. utriculatum.
