1902J NOTES ON' CERTAIN SPECIES OF ANTENNARIA 119 



r 



The stolons, though generally' like those of A. 7ieglecta, are often 

 more leafy, and then resemble those of A, ambigevs, A. peta- 

 loidea, when constituted as a species by Mr. Fernald, was known 

 to him only from northern New England. I have it, however, 



from two localities in Ontario, and Mr. C. K. Dodge has col- 

 lected it repeatedly in St, Clair co., Mich. Undoubted speci- 

 mens of this species have also been secured by Professor De 

 Alton Saunders in the Black hills of South Dakota. This col- 

 lection contains both pistillate and staminate plants. The latter 

 are 8-13^"^ high, with two to four heads to the cluster, the bracts 

 with oval to oblong, obtuse tips, and the pappus bristles with 

 moderately and uniformly thickened upper portions, or occa- 

 sionally very slightly dilated at summit.

I have examined the type of A. Farivellii, and find that it is 

 J nothing else than A, petaloidea Fernald. What Mr. Fernald ^ 



and Dr. Britton^ have supposed to be A. Farwcllii is not that spe- 

 cies, but a much larger-leaved plant closely allied to A. ambigens. 

 The basal leaves in the type are lightly tomentose above, indis- 

 tinctly 3-nerved beneath, only 3-4''™ long, and not exceeding 



13""^ in width.

 The typical form of this species is a New England plant with 

 leaves green and glabrous above from the first, with stems beset 

 with purplish ciliate hairs and with large involucres of narrow 

 acuminate inner bracts. There are some deviations from this type 

 even in the New England states. The ciliate hairs are at times 

 absent, and the basal leaves often slightly arachnoid above. 

 Some Illinois specimens examined by me are also somewhat 

 arachnoid on the upper surfaces of the leaves, and very few cili- 

 ate hairs are present. In plants from Washington, D. C, and

vicmity the ciliate hairs are present in some, absent in others, 

 the leaves either wholly glabrous above or nearly so and the 

 involucral bracts either broad and obtuse or rather narrow. It
