Leedy's Roseroot Recovery Plan ('Sedum intergrifolium ssp. leedyi')

摘要

Sedum integrfolium ssp. leedyi (Rosendahi and Moore) Clausen (Leedys roseroot) was first collected by John Leedy in 1936 at the plants type locality, characterized as 'northeast-facing cliffs of limestone, North Branch of Root River opposite Herman McDaniel farm about 5 km south of Simpson, Olmstead (sic) Co., Minn.' (Clausen 1975). First described as a new variety of S. rosea (roseroot) on the basis of three collections from the type locality (Rosendahl and Moore 1947), the taxon was redefined by Clausen (1975) as a subspecies of the western species S. integrifolium on the basis ofa specimen collected by John Leedy in 1942.
