Creek in Rye Valley, alt. 2,800 ft. 
The specimens from the locality in Rye Valley should be re- 
fered to F. Americana, var. microcarpa, A. Gray, if this variety 
could be maintained. 
It was published by Mr. Buckley as F. albicans, and by Dr. 
Vasey as F. Curtissü, and then finally by Dr. Gray as cited above. 
It is evident now that the variety is founded on abortive fruit. 
This is clearly shown by the fact that the tree in question pro- 
duced on the same panicles in addition to some perfect and mature 
fruit a large number of small and seedless samaras.
