:N0RTH AMERICAN' NEILLIiEL 31 



as well as the five-veined leaves, often broadest above the 

 middle and only slightly 3-lobed almost at the apex, are all 

 very striking. The pubescence, stellnie as in otlier species, 

 is variable in its quantity, except upon (he pedicels, calyces 

 and carjjels, where it is always dense. The reduced peduncu- 

 lar leaves hick the digitate venation displayed in those of the 

 sterile shoots, and have an angular outline ; but all their 

 lobes and teeth are rounded. The flattened orbicular and 

 merely bifid fruit, so small and entirely hidden within the 

 large closed calyx, is like the silicle of a large Lcpidinm in 



appearance. 



Notwithstanding its many and strong peculiarities as a 

 species, I suspect that the Neillia of Montana will be a part 

 of this, and that the same may be true of more or less of that 

 which, derived from Nevada and some parts of Utah, has been 

 referred to the "iV. Torreyiy" i.e., the preceding species. 



Geographical Distribution of Western 



Unifolia. 



My recent extensive journeyiiigs through Eocky Mountain 

 and Pacific coast states and territories taught me several 

 things concerning the distribution of our UnifoJium species, 

 so that I am able to correct a few wrong inferences hazarded 

 in some earlier paragraphs, to which I now revert. 



U. LiLiACEUM, Greene, Pitt. i. 280. My type of this species 

 is a plant collected by myself in Siskiyou County, California, 

 as long ago as 1876. Dr. Gray at the time called it ">S. 

 sirlldfa;' to which I never could agree. The plants were 

 found in shady places along streams ; and the herbage had 

 that peculiar bright green hue which is characteristic of U.
