PROLIFICATION OF THE FRUIT IN CAPSICUM AND PASSIFLORA. 
BY J. ARTHUR HARRIS. 
The appeurance of a recent paper on the influence of 
cold in the production of cleistogamy and teratological 
phenomena in Solanum Melongena and in Capsicum 
annuum, by Dr. G. Mottareale,* has induced me to put 
into print notes and drawings made some years ago at the 
Missouri Botanical Garden. These observations were made 
upon a very large series of fruits from plants grown in the 
open and are consequently interesting for comparison 
with those studied by Mottareale. Since they refer chiefly 
to an anomaly which he was not able to study extensively 
it seems best to present the notes in full with most of the 
figures as originally prepared. Observations on prolifi- 
cation of the fruit of Passiflora are also added. 
CAPSICUM. 
The material studied by Mottareale was grown under the 
following conditions. In three large greenhouses the prin- 
cipal plants cultivated were Phaseolus vulgaris, Cucumis 
sativus, Cucurbita Pepo, Solanum Melongena, Capsicum 
annuum, C’. grossum, and Lycopersicum esculentum. Dur- 
ing the early part of the winter the heating plant had not 
yet been installed, but owing to the mild climate the 
plants made a vigorous vegetative growth and were begin- 
ning to produce normal flowers when, about the middle of 
December, two or three nights of cold wrought havoc with 
them. The egg plants and the peppers lost their flowers 
and most of their leaves, and the more tender apical shoots 
blackened and dried. But the vitality of the plants was
