Summary. This flora has affinities with that of the shallow 

 pine-barren ponds and with that of the intermediate sand-hills 

 (and consequently more remotely with intermediate pine-bar- 

 rens) , but contains a few species not known elsewhere in the 

 region. 



The woody plants are mostly evergreen, as is often the case, 

 and the herbs are nearly all perennial, as usual. 1

 Phrenological diagram for 30 plants of sand-hill ponds. 



The number of flowers seems to culminate about the last of 

 July, with 18 species in bloom, but decreases to none in Septem- 

 ber. The average flowering period is nearly as long as that of 

 cypress ponds, namely, 53 days.
