An examination of the major works on tropical fruit 
plants indicates that So/anuwm Topiro has been completely 
neglected and probably unknown as a cultigen. As Fen- 
nell (Fennell, J. L. ‘*Cocona—a desirable new fruit’* in 
For. Agric. 12 (1948) 181) has written: ‘To what ex- 
tent, if any, the cocona [Solano Topiro] may have reached 
the gardens of the outside world is difficult to say. That 
it appears even now to be essentially unknown to horti- 
culture leads me to believe, in light of its impressive ap- 
pearance and apparent usefulness, that it may never have 
previously left its secluded habitat as a recognized fruit 
of value.” 
The first serious attention paid by botanists to Sola- 
num Topiro as a cultigen dates from the middle of the 
1940°s. During this period, seeds of the plant were col- 
lected ‘‘from the little-explored reaches of the upper 
Amazon” (presumably in Peru) and established in the 
Kxperiment Station at Tingo Mariain Peru. Eventually, 
it was introduced to the Instituto Interamericano de 
Agricultura Tropical in Turrialba, Costa Rica, loc. cit. ; 
Ochse, J. J. ‘Solanum hyporhodium or cocona”” in Proc. 
Ila. State Hort. Soc. 66 (19538) 211), from which centre 
it began to attract horticultural attention. 
The vernacular name for Solanum Topiro in Peru is 
reported to be cocona. This is borne out by notes on her- 
barium specimens (Ad/lip & Smith 27367, 27823) collected 
inthe Amazonian part of Peru in 1929. Inthe Putumayo 
region of Colombia, the plant has two vernacular names 
—cocona and, amongst the settlers recently arrived from
