Hab. Parasitic, chiefly on the Sour Gum ( Nyssa) : very rare. Stem 9 to 18 inches high; berries white. 



Obs. This singular little evergreen was formerly to be met with in several places, in this vicinity; but t 

 do not now know of one. The last one within my knowledge, was procured by some credulous persons 

 as a sort of amulet, or remedy against Epilepsy- My specimens are from Maryland, and New Jersey, — 

 where I have seen U in great abundance, — and invariably upon the Sour Gum (Nyssa sylvatica, of this Cat" 

 alogue). I have not met with the plant in flower; but collected it in fruit, in the month of January.
