 gfratified in findingf, both in Mr. Drummond's and Mr. Douglas's collections, specimens of this interestingf plant, 

 which I had long ago received from Mr. Menzies under the name of "Ilex vomitoria" of Ait. But that plant It 

 cannot be; the flower, as figured in Jacq. Tc.Rar. t 310, being totally at variance with that oi the present 

 species. I still retain it where Nuttall has. placed it, in the genus Myginda. In many points, indeed, it differs 

 from De Candolle's character of that genus; in none more than in the direction of the ovnlps. But M. Kunth 

 has shown, that in his M. myrsinoides the ovules are, as here, erect; still the situation of the disk makes mo 

 think tliat it ought to be removed from Myginda; for here it covers the mouth of the tube of the calyx, as 

 in the genus Thamnea of the Order BruniacecB; there, and there only, uniting the germen with the calyx, in 

 which that germen is, nevertheless, almost wholly immersed. The fruit was, unfortunately, not detected by 

 any of our Naturalists. Pursh describes it as a one-seeded, blackish-purple, ovate drupe. But his characters 

 of the flower are extremely incorrect, nor is their structure at all like that of Myginda BJutcoviaf from the 

 West ludies, to which he compares it.

Hab, Canada. Pursh. — According to Pursh, this Evergreen-tree reaches to a height of eighty feet, having 

 a trunk four feet in diameter. Probably it is only in the southern States that it attains this size. Torrey 

 says that, in the middle States, it is but thirty to forty feet in height, and often only a large shrub.
