TOMATO-NIGHTSHADE CHIMERAS 
With PLaTe CXXI 
Through the courtesy of Dr. Hans Winkler, director of the 
Hamburgische Botanische Staatsinstitute, the New York Botan- 
ical Garden has recently received two living plants of each of 
the tomato-nightshade chimeras known as Solanum tubingense, 
S. proteus, S. Koelreuterianum and S. Gaertnerianum. These 
plants have been supplied from Dr. Winkler’s stock and are 
descended directly by means of vegetative propagation from the 
first of these chimeras produced by Dr. Winkler several years ago. 
The production of these plants, together with the investigations 
which were thus stimulated, coastitute a most important series of 
and the possibility of the production of real graft-hybrids. These 
ie possess therefore an unusual interest to botanists, horti- 
culturists and all others interested in the problems of heredity 
Previous to these investigations, there was much uncertainty 
concerning the origin and the nature of certain plants generally 
known as ‘“‘graft-hybrids” or “mixed fruits,’ of which several 
forms were well known in horticulture. 
e of these is the Bizzaria sa of which there are several 
types to be ne eee On these Bizzarias, there may be pro- 
duced on some branches oranges, on other branches citrons, 
and on aa hee that are part orange and part citron. 
first Bizzaria apparently appeared in Florence, Italy, about 1644. 
For a time the plant was quite generally propagated by budding
