2IO THE AMERICAN MIDLAND NATURALIST 



had a woolly subterranean indument. In his manual the partnership 

 with A. fulgens has been dissolved, and the two others have been 

 joined in one species, A. pedunculata. Here it might have been 

 quite convenient to acknowledge A. monocephala as a variety in 

 place of letting it be swallowed "body and bones" by the species. 



His description of Rosa Woodsii Dindl. comes very closely to 

 fit in with my R. deserta which he places as a synonym. It remains 

 a remarkable peculiarity that the habitat of the former is river 

 banks and copses while the latter has been found only on nude 

 plains with deep gravel and no other grass but bunch grass. A 

 definite description of R. Woodsii was much needed, as all the 

 manuals have separate, very divergent views of their own regarding 

 it. The same is the case with R. Fendleri Crepin, whose original 

 area (vide Flora of Montana) is the southwestern states, but in 

 the present manual has been extended to South Dakota. My 

 R. poetica from North Dakota, though quite different from the 

 descriptions of R. Fendleri in Coulter's and Nelson's manuals, 

 agrees with Dr. Rydberg's, though with some exceptions. R. 

 Lunellii Greene is deservedly recognized among the roses. They 

 number 30 species. 



Another of Dr. Greene's species, Antennaria Lunellii, has been 

 reduced to synonymy under A. campestris Rydb., which belongs 

 to his group VII Campestres (defined in the key as having "leaves 

 glabrous above." In A. M. N. Vol. II, p. 81 (191 1) Dr. Greene 

 described A. Lunellii thus: "Folia superne sericeo-tomentosa, 

 indumento vix vel tardissime deciduo." In fact, this indument is 

 permanent on the living plant during the entire season (except 

 possibly on a small spot in the center of the leaf). The avalanche 

 of melting snow in the earliest spring during the following season, 

 though, is apt to sweep it away from the dead leaves. — Under 

 A. micropkylla Dr. Rydberg says: "A. solstitialis Lunell is the 

 staminate plant, which is smaller." This is one of the reasons 

 why I made it a var. in A. M. N. Vol. V. p. 61. (191 7). The 

 sterile A. microphylla is a tall and rare plant, not different in 

 appearance or size from the fertile one. These two questions on 

 Antennaria occur to me as being my sole disagreements with Dr. 

 Rydberg's views. 



The Lesquerella arenosa (Richards.) Rydb. we believe should be 

 identical with L. Lunellii lutea A. Nels., which this author at first 

 considered to be L. montana and whose habitat is "in arenosis."
