In August number of Gardeners' Monthly, p. 228, in speaking of the " Clammy Locust," (Robinia viscosa) you say, " It is remarkable that this species, discovered by Michaux in the Caro-linas, has never been found wild since his time, and the species is now only known by garden specimens".

This is an error. If you will refer to Vol. IX. of the Tenth Census Reports, (1880) "Forest trees of North America," by Prof. C. S. Sargent, (p. 56) you will see his remarks under description of that species, that it is - " very rare, and not re-discovered until 1882, by the numerous botanists who have visited, during the last thirty years, the localities where the Michauxs, father and son, discovered the species." He gives as the locality, "Open woods, slopes of Buzzard Ridge, altitude 4,500 feet, near Highland, Macon County, N. C. I. Donnell Smith".

I will state also, that I have in my herbarium, flowering specimens collected by Prof. L. R. Gibbes, of Charleston, in 1881, in the very same locality as cited above. Dr. Gibbes also sent me mature seeds, but they failed to germinate. I have also in my herbarium, a specimen (without fruit or flowers) sent me by Dr. Chapman as having been collected " by I. Donnell Smith, in the mountains of North Carolina," probably the same locality.
