Clayt. n. ; According to the correspondence assembled by Darlington,^ roots of what was evidently the same species were sent by John Bartram to Peter Collinson in 1740. The latter at first questioned its distinctness from the European " Greek Valerian ", but later noted differences between them in stature and blooming-time. Linne« cited the Gronovius record under the European P. coeruleum in the first edition of the Species Plantarum; later, however, he saw a color-plate of it among the illustrations of plants in the Gardeners' Dictionary by Miller,* and, realizing their distinctness, gave the American species the name it now bears, in the 1759 edition of his ;* As the plant illustrated had been sent by Clayton to Gronovius, the type locality of the species is to be taken as eastern Virginia. Not feeling bound by the principle of priority, Salisbury « proposed the appro- priate name P. humile, but the rules of nomenclature prevent its adoption. On the other hand, one published by Rafinesque,^ P. quadriflorum, is meaningless and well deserves rejection. Many years later Brand® based a variety p macrophyllum on a specimen showing abnormally large leaflets, and Wetzstein * termed the albino mutation P. reptans album. Geography.âIn contrast to the other eastern species, Polemonium reptans is both common and widespread, having a range nearly as vast as that of Phlox divaricata. Though rare in the Coastal Plain, it is abundant in piedmont, mon- tane, and interior physiographic provinces, from northwestern Georgia to Arkansas, easternmost South
