' The lino between tlio gioups of Riddellia is not well dr.'iwn on the .sizo of Ibo rays, as in Gray, 

 Syn. Fl.ii. pt. I. pp. 317, U18. Tliia plant has the sliort rays oi li. aratknoidea, but the glabrous 

 acbenes and entire palese of the pappu.^ of R. tagetina, with which apecioa it is therefore ])laced. 



On examination, the following numbers had to be transferred to Riddellia tagetina Kutt. i (1) No, 628 

 of Mexican Boundary Surrey; (2) a pbuitfrom Xew Mexico, sent in 1887 by "W. B. Pease ; (3) New- 

 berry's plant in McComb's expedition from the "Hills on the Cbamai" (4) Lettcrman's plants, sent 

 in 1882, from Big Springs, Tex. 



Ur. A\''at8on, to whom this matter had been referred for counsel, said, in a letter on the subjcett 

 "Dr. Gray evidently made too little allowance for variation in the rays of the first group in the genua. 

 In fact, It is only in R. Oooperi that the ray reaches the dimensiona given. In R. taijetina it is any- 

 where from 2 to 3 lines in length."
