Pursh describes a variety with pubescent leaves growing 

 in Pennsylvania, wihch, he says, appears to be a new species. 

 In all my specimens the leaves are decidedly pubescent be- 

 Jieath ; and they are thus described by -E / / i o r f, in the south-

IIab. In Pennsylvania ? -f J\ru ttall remarks that he saw- 

 in the Herbarium of Z. Collins, Esq. a specimen of this plant; 

 communicated by Mu hlenb <? r^-, and said to have been col= 

 lected in Pennsylvania. I doubt, however, if it was not a gar- 

 den specimen. In Mu hlenberg's Catalogue its habitat, 

 is stated to be "Washita, Penn. H." {Hortis.) I have spe^ 

 cimens from Florida, collected by Cafit. Lee on te.
