186 PROCEEDINGS OF THE AMERICAN ACADEMY 



S. MULTiRADiATA, Ait. Some of the specimens apparently true; 

 one is S. 7-ugosa, Mill. 



S. RiGiDA, L. From Muhlenberg. 



S. no. 15986, sent by Muhlenberg as No. 300, is S. Canadensis, 

 var. scabra, Torr. and Gray's Flora, and apparently the S. scahra of 

 Muhlenberg, according to the description in his unpublished Flora 

 Lancastriensis. Muhlenberg's own herbarium in its existing state 

 throws no light upon the question. 



V. Of Willdenow, Enumeratio Planiarum Hort. Reg. BeroUnensis, 1809. 



S. RECURVATA. Cultivated plant, best described as between S. 

 gracilis, Poir. (a derivative of S. ccesia) and *S'. uhnifolia, not 

 matched by any indigenous specimens. A plant cultivated under this 

 name in the Berlin Garden, 1838, 1839, seems like a hybrid between 

 S. ccBsia, var. paniculata, and S. Canadensis. 



S. LIVID A. Cultivated plant, best described as between S.fuscata, 

 Desf., and S. ccesia, var. paniculata. Some indigenous specimens of 

 S. ccesia seem to indicate this as its original. 



S. HIRTA. Folios 2 and 3 belong to S. rugosa, Miller, a form 

 with erect inflorescence and rather large heads; and fol. 1, an imper- 

 fect and uncertain specimen, may be of the same species. 



S. LiTHOSPEUJiiFOLiA. Two sheets ; same as S. viminea, Ait., but 

 more puberulent and broader-leaved ; being probably a state of *S. 

 sempervirens much changed under long cultivation. But the aspect of 

 the cultivated plant is very unlike that of S. sempervirens. 



S. FRAGRANS. Cultivated plant : a narrower-leaved form of S. 

 lateriflora, Willd., Spec, viz. S. elliptica, vai-. axillijlora. 



VI. Of Polret, Diet. {Enc. Meth.) viii. 1808. 



The original species are the following, including those of Desfon- 

 taines. Cat. Hort. Par., or rather Tableau, Bot. Mus. 1804. 



S. GLABRA, Desf. The S. serotina. Ait. Still common in Euro- 

 pean cultivation. 



S. CONFERTA, Poir. Described from herb. Desfontaines ; is S. 

 nemoralis. Ait., as appears from the original, now in the herbarium of 

 Dr. Cosson. 



S. GRACILIS, Poir. A slightly changed form of S. ccesia, L., cult. 

 Hort. Paris. &c.
