monoical axillary spicate, male spikes terete 

 verticillate triandrous shorter tiiaii leaves, fe- 

 male spikes fjlomcrate, berries snowy while. — 

 Kentucky, Illinois, Missouri, etc, parasitical 

 shrub on trees, it blossoms late in the fall and 

 till December, tlowers yellowish, almost simi- 

 lar to those of Genus Osijris (see my disserta- 

 tion,) discovered 1811), indicated 1820 as new. 

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

 with white berries, blended with V, album of 

 Europe by Walter, Muhlenhero- 8cc, or with 

 V. Jiavens and verticlllntum of South Amer. 

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

 ferent from all these. This is the Western sp. 

 the berries are snowy %vhite persistent in Wai- 

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

 pureum of some botanists.
