10 degrees. Some of the plants had succumbed, others were 
not perceptibly injured; still, even of these, some died in 
course of time, the rest flowered in due season. Only in very 
exceptional instances does it occur that the temperature falls 
- for a day or two below zero in this locality. As long as 
Cryptophila pudica was under observation such occurred only 
in 1918 and 1919.. During both winters only a few groups 
were under observation or were discovered shortly after the 
cold waves. These were not injured at all and some of them, 
in time of anthesis, ranked among the finest specimens ever 
seen. The table below shows the.absolute minimums for the 
months September to April with refence to the locality, which 
is taken from the official records of the U. 8S. Weather Bureau 
Station, located up to 1916 in Cullman, but since transferred 
to St. Bernard.. Snow is of such rare occurrence and of such 
short duration that it is of no consequence as a factor: in 
connection with the plant.
