The Simultaneous Origin of Similar (or identical) Varie- 
ties from Different Stock.—In the summer of 1883, there appeared 
in a crop of Challenger Lima Beans (a garden form of Phaseolus luna- 
tus in which the pods and beans are much thicker than the type), 
growing near Newark, N. J., a dwarf plant showing no tendency to 
twine or climb, but in all other respects like the Challenger Lima with 
its distinguishing characteristics highly developed. Eighty per cent 
of the seed product of this plant produced dwarf plants, the remaining 
twenty per cent reverting to the regular Challenger Lima type. Of 
the product of the eighty per cent of dwarf plants, all, or practically 
all were dwarf, and thus a dwarf variety of Phaseolus lunatus was 
established. 
In the summer of 1884, there appeared in a crop of large White 
Limas (a garden form of Phaseolus lunatus in which the pods and 
beans are larger and a little flatter than the type) growing near Ken- 
nett Square, Penna., a dwarf plant showing no tendency to climb, but 
in all other respects like the large White Limas. Sixty-six per cent 
of the seed of this plant produced dwarf plants, and in the succeeding 
generations practically all of the plants were dwarf, thus giving us a 
second dwarf variety of the species. The seed from which the Ken- 
nett Square crop was grown had been produced on the same farm for 
several generations, and there is no possibility of the two dwarf sorts 
tracing back to the same stock within ten generations at least. About 
the same time there appeared a dwarf form of the very distinct Small 
White Lima or Seewell, another garden variety of the species, the 
dwarf plant having all the characteristics of the parent variety except 
the rank growing twining vine. 
Again, the White Plume aud Golden Self Blanching varieties of 
Celery, are of a distinct class of so-called self blanching sorts in which 
the inner leaves assume in one case a white and in the other a yellow 
color as the plants approach maturity. There were no such varieties 
in cultivation until the White Plume appeared in New Jersey and the 
Golden Self Blanching appeared about the same time in France, There
