SUSPECTED SPECIES. 135 



SNEEZEWEED. 



{ITelenium montanum Nutt.) 



A smooth, angular, branching perennial 1 to 3 feet high, with lance- 

 shaped leaves and numerous conspicuous 3'ellow flowers, which appear 

 in autumn. The plant is commonly called sunflower or wild sunflower 

 in Montana. This species occurs abundantly in moist grounds in Gal- 

 latin, Lewis and Clarke, Madison, Cascade, Choteau, and Missoula 

 counties. Its general distri})ution is from Mississippi and Texas to 

 Nebraska, Saskatchewan, and Montana. The closely related Eastern 

 species, H. autumnale L., is known to be poisonous to stock, but no 

 cases have been reported against IT. montanum from the State. 



OREGON YEW. 



{Taxus hrevi folia Nutt.) 



A tree with leaves resembling those of the red flr. The fertile 

 cones are represented by a single ovule, surrounded by a red, thickened 

 disk, which becomes fleshy and berry-like. This species is found 

 sparingly in Montana, west of the Rocky Mountains, at Columbia 

 Falls, Kalispell, Bearmouth, and Lolo. 



The leaves would probabh^ prove fatal if eaten ))}' stock, but inas- 

 much as the tree grows in very inaccessible places, there iu little danger 

 to be apprehended from it. The leaves and seeds of the European 

 yew (T. haccata L.) are well known to be poisonous. 



EAGLE FERN. 



{Pteriii aquilina L.) 



The common eagle or bracken fern has a stout, wood}' rootstock and 

 large leaves, 2 to 4 feet long by 1 to 3 feet wide, which are 3-divided, 

 each branch being pinnatel}'^ compound. It occurs in woodland at 

 Summit, Columbia Falls, Libby, Kalispell, and Missoula, and in the 

 Bitter Root and Deerlodge valleys. The distribution of this plant 

 includes nearl}' all of North America. 



Cases of poisoning of horses and cattle b}' this plant have been 

 reported from England and from a few localities in the United States. 

 No complaint against it has been sent in to the Department of Agri- 

 culture from Montana.
