monoical axillary spicate, male spikes terete 

 verticillate triandrous shorter than leaves, fe- 

 male spikes .eloinerate, berries snowy white. 

 Kentucky, Illinois, Missouri, &c, parasitical 

 shrub on trees, it blossoms late in the fall and 

 till December, flowers yellowish, almost simi- 

 lar to those of Cenus Osyris (see my disserta- 

 tion,) discovered 1810, indicated 1820 as new. 

 We have in N. Amer. at least 3 sp. of Viscum 

 with white berries, blended with V. album of 

 Europe by Walter, Muhlenberg &c, or with 

 V. Jlarens and verticillatum of South Amer. 

 and Antilles by Pursh, Elliot &c, but quite dif-

 the berries are snowy white persistent in Win- 

 ter, purplish when dry ; thus perhaps V. pur- 

 pureum of some botanists.
