details bearing out this supposition. This plant has been 

 named Primus utahensis by Dr. Dippel (Laubholzkunde 3:634, 



1893). 



The Black Utah Hybrid cherry originated with J. E. 

 Johnson at Wood river, Nebraska, on or near the Platte river, 

 probably sometime in the sixties. Mr. Johnson grew native 

 dwarf cherries and sand plums in his garden. Seeds of these 

 cherries were sown. One of the seedlings was saved and 

 propagated. Mr. Johnson soon afterward moved to Utah, 



VULCAN 



whence, it appears, he distributed this variety as the Utah 

 Hybrid cherry. 



Plant dwarfish, 3-4 feet high, twigs somewhat zigzag like 

 P. watsoni, leaves small, narrow ovate, pointed at both ends, 

 somewhat conduplicate and a trifle rough, margins crenulate, 

 glandless, petioles medium short, occasionally with small 

 glands, fruit small, spherical, cherry-like, but with a plum-like 

 bloom ; stone round, cherry-like. 



This hybrid has not proved to be of any practical value, 

 except perhaps in rare circumstances. One of the best of the 

 class is Mr. Kerr's seedling, .Maryland, which see.
