106 SMITHSONIAN MISCELLANEOUS COLLECTIONS [VOL. 50 



Incident to the construction of the railroad from Helena to Great 

 Falls, a considerable collection of plants was made in the cuttings 

 near the latter town, which were reported on by Dr. Newberry in 

 1891. 1 In addition to eight species described as new and belonging 

 to the genera Chiropteris, Zamites, Baiera, Cladophlebis, Sequoia, 

 Podozamites, and Oleandra, Dr. Newberry listed thirteen species as 

 common to the Great Falls field and the lower Potomac of Vir- 

 ginia, three as common to this locality and the Kootanie of Canada, 

 and six as common to the Kome (Urgonian) beds of Greenland. 



In 1890 Dr. A. C. Peale and the writer made a small collection 

 of Kootanie plants from the vicinity of Great Falls and above the 

 mouth of the Sun River, and the following year Mr. W. H. Weed 

 made an additional small collection from the same place, which were 

 studied by Prof. Wm. M. Fontaine, his report appearing in 1892. 2 

 He enumerated fifteen species and varieties, of which number six 

 in the genera Aspidium, Pecopteris, Cladophlebis, and Zamites were 

 regarded as new. 



Also, in 1 891, Dr. H. M. Ami and Dr. Hayden made a considerable 

 collection of plants from the Kootanie of the Cascade coal basin of 

 the Canadian Rockies, which were reported on by Sir William Daw- 

 son, whose report appeared in 1892. 3 This paper recorded twenty- 

 one forms, of which two were new to science (Piiiits and Angio- 

 pteridium) and eight not named specifically. 



The final publication which it remains to notice was based on col- 

 lections made during the years 1894 and 1895, the first by Mr. W. H. 

 Weed and the last by Prof. Lester F. Ward, from a number of 

 localities in Cascade County, Montana, largely in the vicinity of the 

 stage station of Geyser and about forty miles southeast of Great 

 Falls. These were turned over to Professor Fontaine for elaboration, 

 and his report is published in Ward's second paper on the "S.tatus of 

 the Mesozoic Floras of the United States." 4 It includes sixteen 

 species, of which five were described as new, the latter belonging 

 to the genera Dicksonia, Lyeopodites, Cycadeospermum, A r agiopsis, 

 and Laricopsis. 



On compiling a list of all the plants heretofore reported from the 

 Kootanie beds of Canada and the United States, we have a grand 

 total of ninety forms. It is more than probable, however, that if all
