(Columbia). In the Gray Herbarinm there is a poor specimen of the original 
QO. viscida of Nuttall, and this resembles more my plant, which Dr. Gray would have 
included in O. monticola (Jenney’s plants from the Black Hills are ineluded in the 
latter), rather than in O, viscida as understood by him. 
Common around Custer, altitude 1,650 to 1,700 m., June 5 (No, 636).

sericea Nutt.; Torr. & Gr. Fl. 1, 339 (1888). 
All my specimens have yellow flowers. In afew the calyx is somewhat viscid, and 
these can scarcely be distinguished from the preceding species except by the size. 
The bracts are narrower than in the blue-tlowered forms I have seen,

In Coulter’s Manual the stamens are given as diadelphous (5 and 1), in Gray’s 
Manual as diadelphous (9 and 1) in the key, but as 5 and 1 in the description of the 
genus. Inall flowers investigated, they were 9 and 1, but the united stamens were 
of two different lengths, every second one being shorter.

I. americana and this plant grow together sparsely everywhere in Nebraska. I 
have not seen any intermediate forms, but they both grade into the variety truncata. 
Hot Springs, altitude 1,050 m., June 16 (No. 643).

Lathyrus ochroleucus Hook. Fl. Bor. Amer. i., 159 (1853). 
Common and very luxurious in the Black Hills. It is regarded as a very good 
fodder plant, and may be of economic value.

Prunus pennsylvanica L. f. Suppl. 252 (1781). 
In the Black Hills it never becomes a large tree. The largest specimens I saw

not much taller than the preceding, and has generally folded leaves.
