DESCRIPTION OF FOSSILS 509 



Genus Nyssa, Gron. 



Nyssa jonesii, Perkins, Vermont Report, 1903-1904, page 197. 



Plate 86, figure 8. 



Fruit much like that of some modern species. Form elongateoval, 

 unequally ribbed ; length 20 millimeters, width 9 millimeters. 



Nyssa lescurii, Hitchcock, Portland Society of Natural History, volume i, 



page 95. 



Plate 86, figure 9. (Enlarged twice.) 



Fruit elongate-oval, slightly taper-pointed at one end, more obtuse at 

 the other, regularly twelve-ribbed, surface horizontally wrinkled ; length 

 22 millimeters, width 10 millimeters. 



Nyssa lamellosa, Perkins, Vermont Report, 1903-1904, page 195. 



Plate 86, figure 10. 



This is much larger than other species of this genus, and the ribs of 

 other species become thin lamellae, as is the case in some living species, 

 as Nyssa ogeche, which the fossil species much resembles, although it is 

 much larger. This species is long-oval, somewhat flattened, the surface 

 bearing eleven longitudinal lamellae. These are from five to seven milli- 

 meters high and very thin. The ends of the fruit are mucronate. Length 

 37 millimeters, width 20 millimeters. 



Nyssa crassicostata, Perkins, Vermont Report, 1903-1904, page 196. 



Plate 86, figure 11. (Enlarged 1£ times.) 



It is possible that this and the species figured as 9 should be classed 

 together, but they seem to afford specific differences which are more 

 apparent in the actual specimens than in the figures. This species is 

 shorter, thicker, and less symmetrical than N. lescurii, and the costaa are 

 heavier. The ends are blunt pointed. Length 20 millimeters, width 

 10 millimeters. 



Genus Prunoides, Perkins, Vermont Report, 1903-1904, page 209. 



. Prunoides seelyL Perkins, Vermont Report, 1903-1904, page 209. 



Plate 86, figure 12. 



Fruit closely resembling a plum stone, surface smooth almost polished 

 in the center, rough on the edges; length, 15 millimeters; width, 11 

 millimeters. This is a rare form, only two or three specimens having 

 been found.
