328 PROCEEDINGS OP THE AMEPvICAN ACADEMY 



little duubt, to R. Carolina, and the spccimeus in Willdcnow's herba- 

 rium, us found by Crepin, confirm this view, at least in part. 



In the second edition of the Hurtus Kcwensis (1811), by the 

 younger Aiton, the only change made from the first is in the addi- 

 tion of R. ruhifoUa (usually credited to Robert Brown, though not 

 included in his IFbrZrs), based upon a pubescent form of 7i?. setiyera 

 that had been introduced into the gardens of luigland. 



In 1814 Pursh published the Flora Americce Septen/rtonolis, in 

 which he adopts all the species (and descriptions) of WilLlenow's 

 Systcma and Enumeratio, adding Michaux's R. setigera and Alton's 

 R. 7-ubifulia, as also two new species, R. Lyonii, which is a west- 

 ern fui m ajiparently of R. humilis, and 7?. suaveolens, which is the 

 introduced Eglantine (7?. ruhiginosa). AYilh Aiton and ^^'illdL•now, 

 he retains the Linnaian R. pendulum as American, though he states 

 that he had never seen it indigenous. He is evidently at fault in his 

 understanding of several of the species, his R. nitlda and R. geinella 

 being both probably R. humilis, and his description of R. blanda is 

 so modified in the appendix as to show that R. nitida is meant. He 

 also describes an introduced gai'den species as R. lutescens. 



Dr. Bigelow in his Plants of Boston (1814) recognized but a single 

 native species {R. Carolina) in the region about Boston, and in the 

 later editions of 1824 and 1840 expressed the same opinion. He 

 may well have been encouraged in this belief by his experience (as 

 narrated by Amos Eaton) in sending '• three specimens to the greatest 

 botanist iu Europe [Sir J. E. Smith], which were all taken from dif- 

 ferent parts of the same plant. He received an answer, making two 

 of the specimens different described species, and the third one a new 

 species." 



In the same year Rafinesque published in the Precis des Decouvertes 

 two new species, R. jlexuosa and R. enneaphylla. The last may be 

 referred with sufficient confidence to R. Carolina, while the first is 

 evidently the introduced R. canina. As the name R. Jlexuosa was 

 preoccupied, Trattinnick afterwards proposed for this the name R. Raf- 

 Jinesquejana. In 1816 Poiret published, with descriptions, in the sup- 

 plement to Lamarck's Dictionnaire de Botaniqiie, two species whose 

 names Bosc had previously proposed in the catalogues of the Paris 

 Garden, and which were supposed to be of American origin. The 

 R. ruhrispina is identified with R. nitida. The R. Evratina, however, 

 as afterward figured by Redoute, appears to be a European species. 

 His R. rapn, on the other hand, which is credited by Poiret to Scot- 

 land, has been supposed to be a double-flowered form of R. lucida.
