tions of incised bases of the lateral leaflets or a decurrent distal 

 pair, or subleaflets in the position of stipels. The stipules of A. 

 Brittonia)ia are narrower and more incised than those of hirsuta, 

 and the bracteoles are notably unlike. The fruit, which is more 

 crowded and closely reflexed, is of a different form, wanting the 

 expanded marginal rim, tumid disk and contracted base charac- 

 teristic of the fruit of hirsuta and, at maturity, presenting a signally 

 diverse appearance from all our species by reason of the conical 

 mass of connivent bristles. 



From A. mollis the species differs in greater size, the stouter 

 stem harshly hirsute instead of loosely villose or tomentose-pubes- 

 cent, larger and thicker acuminate leaves provided with shining 

 glandules on the lower surface and quite wanting the obovate or 

 oblong figure and crenate or dentate margins of those of mollis, 

 larger, more crowded flowers, much larger, more turbinate and 

 deeply sulcata fruit having the bristles crowded and connivent in- 

 stead of loosely ascending or erect. 



The general character of the pubescence and branching of A. 

 Brittoniana is much like that of A. pan>iJlora,a.nd the glandules be- 

 neath the leaflets present nearly the same appearance in both spe- 

 cies. Other, if slighter, evidences of relationship between the two 

 plants may also be noted, such as the sharply serrate often narrow 

 leaflets of Brittoniana, the occasionally decurrent distal pair, the 

 narrow and numerous subleaflets, the elongated racemes. These 

 characteristics are more or less destinctive of Brittoniana among 

 our species other \}[\z.n parviflora,\n which they all find a more pro- 

 nounced expression. The fruit of the two species is, however, re- 

 maikably different. 



A. Brittoniana is in fact very distinct from any American species 

 while nearly related to certain Asiatic forms — A. viscidula Bge., 

 A. pilosa Ledeb. and A. Daluiiica Willd., plants which have been 

 variously confused together by authors, and all of which have finally 

 been referred to A. Eupatoria L.
