260 BROOKLYN BOTANIC GARDEN MEMOIRS 



The species is dedicated to Prof. C. R. Orton who was the first to 

 separate the material from the opsis-form. The following is a list 

 of the specimens from other localities in the Arthur herbarium. 



Dodecatheon alpinum Greene — Susanville, California, 5,000 ft., 

 June 30, 1897, II, iii, M. E. Jones; Bluff Lake, San Bernardino Mts., 

 California, 7,400 ft., Sept. 1895, III, Miss Nora Pettibone, 2853; Mt. 

 Eddy, Siskiyou Co., California, Sept. 7, 1903, i, ii, III, E. B. Copeland, 

 (Sydow, Ured. 1774, type). 



Dodecatheon Jeffreyi Van Houtte — South of Sitka, Alaska, ii, III, 

 Aug. 29, 1916, J. P. Anderson, jj 7; Vancouver Island, British Colum- 

 bia, Aug. 26, 1908, ii, III, E. W. D. Holway. 



Dodecatheon {tetrandrum Suks.?) — Mt. Adams, Washington, 6,000- 

 7,oooft., Aug. 31, i886,W.N.Suksdorf(Barth. N.Am. Ured. 554, 2457). 



142. PucciNiA OxYRiAE Fckl. Symb. Nachtr. 3: 14. 1875. 

 On Polygonaceae : 



Oxyria digyna (L.) Hill — Strawberry Mt., 8,000 ft.. Grant Co., 

 Sept. 2, 1913, W. E. Lawrence, 1112. 



Evidently a rather rare species represented in the Arthur her- 

 barium otherwise only by single collections from Colorado, Utah, 

 Idaho, Alberta and British Columbia on the above host. 



143. PucciNiA Palmeri D. & H. Erythea 7: 98. 1899. (Not 



Aecidium Palmeri And. 1891.) 



Allodus Palmeri Orton, Mem. N. Y. Bot. Gard. 6: 202. 1916. 

 (Not ^. Pa/ wen Arth. 1906.) 

 On Scrophulariaceae : 



Pentstemon Menziesii Hook. — Near Mt. Jefferson, Linn Co., July 

 3, 1914, F. D. Bailey, J 04^5; Mt. Hood, 6,000 ft., Sept. i, 1901, E. W. 

 D. Holway; Horse Creek, Wallowa Co., June 24, 1897, E. P. Sheldon, 

 8368. 



This is an opsis-form common in the Rocky Mt. and north Pacific 

 states. Dietel & Holway (1. c.) based their combination on Aecidium 

 Palmeri Anderson. This Aecidium, as has been recently determined 

 by Orton, working in this laboratory, is the aecial stage of the heter- 

 oecious rust P. Andropogonis Schw. and not the aecia of this species. 

 While the name P. Palmeri D. & H. has been misapplied in this way 

 it seems best to retain it for this species, particularly since the telia 

 described apply to this fungus. 



144. PucciNiA Parkerae Diet. «& Holw. Erythea 3: 78. 1895. 

 On Saxifragaceae : 



Ribes lacustre (Pers.) Poir. — Whitewater Ranger Station, near 

 Mt. Jefferson, Aug. 28, 1916, H. P. Barss, 3398; Hood River, July 

 23. 1915.30/^.
