| CAYUGA FLORA (1926) NOTES: Marl springs and meadows; scarce. June 10-30. Spring, Inlet Valley s. of Enfield Creek; Junius marl ponds (D. !) ; prairie n. of Crusoe Lake. Dudley gives some other stations, but whether these refer to this species or to C. woodii is uncertain. Mass. to Man., southw. to D. C. and Mo.; rare on the Coastal Plain. The differences between C. tetanica and C. woodii are fairly constant, but they are almost entirely in connection with the lower part of the plant, and might be suspected to be due to the radically different type of soil which each inhabits although this does not seem to be the case. Without structural characters in the inflorescence, the separation of these two species by the characters given is not very secure. |
