The Flora of the Cayuga Lake Basin 325 



A Dudley specimen in the C. U. Herbarium, labeled " Thaspium aureum Nutt," 

 is Zizia aurea. Since this specimen is from the only station given by Dudley for 

 Thaspium aureum, the inclusion of the latter species in the Cayuga Flora was 

 undoubtedly an error.
