﻿476 Small : Studies in the Botany 



In the lower country, Louisiana. 



Many distinct species are now associated together under the 

 name of Solidago Boottii. The one just described belongs to this 

 series and formed part of S. Boottii ,9 of Torrey & Gray.* It is 

 peculiar in being glabrous or nearly so above and with more 

 or less pubescence on the lower leaves. The inflorescence is pan- 

 iculate and very loosely disposed, while the branches of the panicle 

 and the elongated peduncles are filiform or nearly so and quite 

 weak. The teeth of the leaf-blades are more remote and appressed 

 than those of 5. Boottii. 



The original specimens were collected by Dr. Leavenworth in 

 Louisiana. 



Solidago plumosa. 



Perennial, bright green, glabrous or nearly so below the in- 

 florescence, inclined to be glutinous, especially above. Stems 

 erect, often tufted, 4-10 dm. high, ridged, purple, strict : leaves 

 alternate ; blades spatulate to narrowly linear, 2-30 cm. long, ob- 

 tuse, acute or acuminate, thickish, entire or remotely and shallowly 

 toothed, narrowed into slightly margined petioles or the upper ones 

 nearly sessile with smaller ones sometimes clustered in their axils : 

 heads numerous, in narrow terminal panicles, 5-8 mm. long, often 

 densely disposed : involucres campanulate at maturity : bracts 

 linear, inner ones narrowly so, obtuse, erect: flowers 1 1— 1 5» 

 crowded; rays 3-5, yellow, 5-6 mm. long: achenes 3-3.5 mm - 

 l° n g. glabrous. 



In canons of Yadkin River, Stanley County, North Carolina. 

 Summer and fall. 



In a former issue of this journalf I called attention to the 

 form just described as Solidago plumosa, hoping by that means to 

 secure further data on its distribution. I am now convinced that 

 the North Carolina plants are specifically distinct from Solidago 

 Purshii, its more northern homologue. We have in the case of 



Purshii and Solidago pi 



fectly distinct species. The much larger size of the plants in the 

 latter, the longer heads, and the perfectly glabrous achenes, serve 

 to separate the two species.
