188 PROCEEDINGS OF THE AMERICAN ACADEMY 



IX. Of Desfontaines, Cat. Hort. Reg. Paris., ed. 3, 1829. 



S. GLABRA. Same as S. serotina, Ait, first published in Poir. Diet. 



S. NUTANS. A form of S. Canadensis, L. 



S. INTEGRIFOLIA. A Cultivated state of S. sempervirens, L. 



S. HU-MiLis. A low form of S. rugosa, Mill., with inflorescence 

 not normally developed under cultivation. 



S. FUSCATA. Species of unknown source, introduced into the Paris 

 Garden about the year 1828, first mentioned in the additamentum to 

 Desfontaines' Catalogue, p. 3G2, as «S^. fusca, Hort. Par. ; in the adno- 

 iationes, p. 402, characterized as S. fuscata. It is a smooth and gla- 

 brous and rather freely branching plant, in the virgately thyrsoidal 

 and not at all secund inflorescence recalling S. puberula, but with 

 broader and obtuse involucral bracts, the stems purplish. Not identi- 

 fied with any indigenous species. 



S. PLANTAGiNEA. The Same as S. eUiptica, Ait. 



S. MULTIFLORA. First published in Poir. Suppl. v. 461, in culti- 

 vation down at least to 1869 ; it appears to be related to S. nlmifolia 

 as S. humilis is to S. rugosa, viz. a form in which the leaves have be- 

 come firmer and the panicles less evolute by exposure under cultiva- 

 tion. No indigenous specimens well correspond. 



S. ASTERULA. Apparently the same as the plant cultivated in the 

 Paris Garden under the unpublished name of aS. rigidida, Bosc, from 

 about 1828 to 1831, not recognized in the wild state, perhaps derived 

 from the preceding or from S. Elliottii, or from S. rugosa, which the 

 hirsute pubescence of the upper part of the stem strongly suggests. 



S. GRANDiFLORA. This I take to be a tall cultivated state of 

 S. littoralis, Savi, of the Italian coast, a species quite distinct from 

 S. Virgaiirea. " .S*. Narhonensis, Pourret, in Act. Tolos. iii. 329," which, 

 if actually published, has been overlooked, is perhaps the same species. 



X. Of De Candolle, Prodromiis, v. 1836. 



S. Cleli^. Probably S. elliptica, Ait., var. axilUJlora, Gray, and 

 the same as S. duhia, Scop. Del. Insub. t. 10. 



S. SCABRIDA. A Mexican species, seemingly only a larger-flow- 

 ered S. Canadensis, var. scahra. 



S. DECEMFi.ORA, is S. uemoralis^ Ait., from Texas.
