shrubs. There are more evergreens among the small trees and 

 vines, but it is probably safe to say that not one-tenth of the 

 vegetation is evergreen; which can hardly be said of any other 

 equal area in Florida, outside of the alluvial bottoms of the 

 Apalachicola River. Elsewhere I have found a correlation be- 

 tween scarcity of evergreens and abundance of potassium com- 

 pounds in the soil,* but whether or not that will hold here we 

 have no direct evidence yet. 



Neither Ericaceae nor Leguminosae were observed, for the 

 former seem to avoid lime and potash and the latter humus; 

 but some of the latter might possibly be found in summer. 

 Until a more complete list of plants is available it is hardly 

 worth while to discuss the families most largely represented, 

 the prevailing flowering seasons, colors of flowers, modes of dis- 

 semination, etc. 



Taxodium distichiim, Ulmus fidva, Adelia, Ptelea, Tovara, and 

 Calycccarpwn had not been reported from this region before, but 

 most of them can be found on the Apalachicola River bluffs or 

 in the Marianna red lands farther west. By far the most in- 

 teresting plant in the list is Grossularia echinella. Although it 

 is more abundant in the area under consideration than all the 

 other shrubs combined, it is not known anywhere else in the 

 world, and not described in any book; and therefore some par- 

 ticulars about the circumstances under which it was found will 

 be of interest. 



Soon after entering the rich woods southeast of Dogwood 

 Landing with Dr. Kurz on the date named (Feb. i8, 1924) I was 

 surprised to see a few specimens of a currant or gooseberry 

 (both of which were formerly included in the genus Ribes). 

 Although no such plant had been found anywhere near Florida 

 before, at first it did not occur to me that it might be an unde- 

 scribed species, and I was inclined to refer it to Ribes (Gros- 

 sularia) curvatum Small, whose nearest known stations were 

 Stone Mountain, Georgia, and the mountains of Alabama, 

 over 200 miles away and in a perceptibly cooler climate. Its 

 leaves were then about half grown, and we guessed that it would 

 be in bloom about two weeks later. As the afternoon was then 

 well advanced, we did not go more than a quarter of a mile or so 

 into the forest after finding the first specimens of the gooseberry,
