Discussion

Seymeria cassioides is an obligate parasite of 11 pine species in the southeastern United States; it is also capable of growing on western pines and other conifers (W. F. Mann and L. J. Musselman 1980). Infestations of pine plantations are not common; in sufficient numbers, S. cassioides may produce chlorosis and mortality in cultivated Pinus elliottii and P. taeda (H. E. Grelen and Mann 1973).
