Prof. Don's Monograph q/'Streptopus, ^c. 533 



I am indebted to my highly esteemed friend Dr. Boott, the worthy Secretary 

 of this Society, for native specimens of this remarkable plant, which was ori- 

 ginally discovered by Michaux on the mountains of South Carolina, and 

 afterwards by the late Mr. John Lyon, by whom it was introduced into our 

 gardens in 1811. The plant flowered in May of the following year at the 

 nursery-grounds of Messrs. Fraser, Sloane Square, Chelsea; and a figure of 

 it appeared in the September number of the Botanical Magazine for that 

 year. Dr. Short has since discovered it on the mountains of Kentucky. 

 Pursh records it also as a native of Pennsylvania ; but I am not disposed to 

 place much reliance upon the stations assigned to American plants by that 

 botanist, from their having been in many cases noted down from memory, 

 after the lapse of some years. Although a native of South Carolina, the plant 

 does not appear to have come under the notice of the accurate Elliott, whose 

 account of it is copied wholly from Michaux.
