not entirely destroyed and when provision for a suitable 
temperature was made, the vegetative organs gradually re- 
gained their former luxuriance. But the sexual organs 
were very teratological in nature, and these anomalies of 
flower and fruit Mottareale considers the result of the con- 
ditions of temperature to which the plants were subjected. 
Of the anomalies of the calyx, corolla and stamens, only 
pistillody of the stamens need be mentioned here. In 
Capsicum adesmy of the carpels was noted in several cases 
but we may confine our attention to the internal struc- 
ture of the fruit. Mottareale saw diaphysis of the 
fruit —the production of another imperfect fruit from the 
center of the thalamus, and ecblastesis— the production 
of accessory fruits from the axils of the carpels. Both 
anomalies were seen in some fruits. He found the seeds 
either normal, abortive, more or less foliaceous, or tending 
to assume the form of a carpel. 
The evidence for referring these anomalies to the influ- 
ence of the cold seems unsatisfactory. He himself tried 
for two successive years to reproduce the result but with- 
out success. Furthermore, anomalies resembling those he 
describes are not infrequently seen in Lycopersicum, So- 
lanum and Capsicum.* Confining our attention strictly 
to the fruit we note the occurrence of pistillody of the 
stamens in all three genera, the occurrence of supernu- 
merary whorls of carpels in Lycopersicum, the rupturing 
of the fruit wall by the placentae in Solanum Melongena, 
and the production of carpel-like bodies inside the fruit of 
Capsicum. 
Terracciano f observed two types of  prolification in 
C. annuum. In one form the walls of the fruit, ter- 
minated by a hollow tubiform style open at the top, 
showed five gibbous evaginations. Internally the fruit
