Summary. Trees and shrubs here form the bulk of the vegeta-

dominate. The phaenological diagram is very similar to that 

 for moist pine-barrens, making allowance for the much smaller 

 number of species involved. The average flowering period 

 too, is nearly the same, 48 days. None of the herbs seem to 

 bloom before April. 



There are about 15 anemophilous species in the list, and the 

 same number with white flowers. Other colors are less abundant, 

 and there are not many conspicuous flowers in the whole lot. 

 Probably the most conspicuous are those of Pinckneya, which are
