Plants Hurt by a Late Freeze. 419 
Vaccinium nitidum Pursh had the open corolla, the exserted 
_ stigmas and the old leaves frozen; the young leaves, unopened 
corollas and small fruit were not hurt. ‘ 
Vaccinium tenellum Ait. had the expanded corolla, exserted 
_ stigmas, young leaves and newly formed stems frozen. The 
young stems were two or three inches long. _ This species is 
evergreen with us. 
It is curious that the old leaves on V. nitidum were frozen 
while on V. tenellum the young leaves suffered. 
Pinguicula lutea Walt. on the moist pine barrens had the 
stapes frozen down to the surrounding débris. The scape 
was frozen to within four inches of the ground and the rest 
left unhurt. 
Young tobacco plants where not protected were killed, but 
the beds in hammocks or on the edges of hammocks escaped. 
Poke weed, Phytolacca decandra L., had grown to bea foot 
_ more high, and was cut back to within four inches of the 
sound. Specimens that were somewhat protected wilted in 
the sun but recovered in a day or two. 
Young beets that were about six inches high had the outer 
and higher leaves frozen. 
Mulberry trees, Morus alba ..,had grown enough to make 
afine shade. The frost killed the younger leaves entirely 
and the older leaves were more or less hurt, so that it was 
difficult to find a perfect leaf within ten feet of the ground. 
“eh figs, F. carica L., had to make a new start. They 
ad made vigorous growth and the young figs were about the 
| “te of a large hazelnut. 
Tradescantia zebrina was entirely frozen. 
“spalum leave had some leaves seven inches long. The 
cuter and more exposed leaves alone sustained injury.
