being referred to as Station 850. There remained a mass of 

 fragmentary leaves and seeds. Some of the best preserved of 

 the latter were subsequently submitted to the U. S. Biological 

 Survey and were determined by Mr. W. L. McAtee. The large 

 collection of recent fruits and seeds gathered together by the 

 Biological Survey and the long experience of Mr. McAtee, in 

 identifying the comparable remains found during extensive 

 studies of the stomach contents of birds, renders these identifica- 

 tions particularly authoritative. Following are the additions to 

 this late Pleistocene flora : 



1. Chaetochloa sp. A caryopsis of a grass of the genus 

 Chaetochloa Scribner. 



2. Sparganium sp. A nutlet of a bur-reed, specifically un- 

 determinable. 



3. Populus cf. deltoides Marsh. The deposits contain abun- 

 dant bud-scales greatly resembling and probably those of this 

 species, the leaves of which have been found in Pleistocene de- 

 posits of very similar age in Alabama. 



4. Polygonum sp. An achene of an undetermined species of 

 the genus Polygonum L. 



5. Viburnum cf. molle Michaux. Two stones, probably repre- 

 senting this species, which is still found in this area. The present 

 range of the species is from Massachusetts to Florida near the 

 coast. 



6. Viburnum cf . nudum L. Two stones, probably representing 

 this species, whose present range is from Long Island to Florida. 



7. An achene of a species of Compositae resembling those of 

 the genus Centaurea L. 



8. A single seeded dry drupe suggesting the family Oleaceae. 



Florida 

 In the vicinity of Milton, Santa Rosa County, Florida, there 

 is a buried swamp deposit of late Pleistocene age containing 

 trunks of a species of Pinus; and stumps, roots, and seeds of 

 Taxodium distichum, as well as undeterminable fragments of 

 dicotyledonous leaves.* 



* This deposit is mentioned in Harper, R. M., Peat deposits of Florida, pp. 295- 

 297, 1910, and without any warrant is referred to the so-called Grand Gulf formation.
