1923] PALMER, THE RED RIVER FOREST AT FULTON, ARKANSAS 19 



one meter or more in diameter being sometimes met with. It is also found 

 on bluffs and banks of small streams where it is usually much smaller. 



Gary a cordiformis var. latifolia Sarg. The broad leaved form of the 

 Pignut is sometimes found on bluffs and in upland woods. 



?/« 



This comparatively rare Hick- 



ory, with its curious nutmeg-like fruit, is perhaps more abundant in the 

 Fulton region than anywhere else. It is found both in low woods and in 

 the flat uplands. It has pale scaly bark and often becomes a fine tree 

 up to 30 or 35 meters tall. 



Carya aquatica (Michx. f.) Nutt. A large tree common in low swampy 

 woods. The bark is usually very shaggy and the wood is said to be of 

 inferior value to that of the other Hickories. 



Carya oralis var. obcordata Sarg. This form of the small fruited Hickory 

 or Pignut, as it is often called in the north, is occasionally found on bluffs 

 or in flat upland woods, and it probably reaches about its southwestern 

 limit here. 



Carya alba (L.) K. Koch. Common in flat upland woods and on gravelly 

 ridges. 



Carya ovata (Mill.) K. Koch. Found occasionally in flat upland woods, 

 but not very common. 



Carya Buckley i var. arkansana Sarg. This is the commonest Hickory 



of the region, and it often forms a large percentage of the woods on flat 



uplands. It is also sometimes found in the low woods, on the sand hills 



and in almost all situations except in the permanent swamps. It becomes a 



medium sized tree up to 20 or 25 meters in height. The wood is valuable 



and is much sought, with that of other Hickories, for handles and wagon 



timber. The bark is rather thick and ridgy but not scaly. The fruit is 



edible but the kernel is closely compressed in a thick shell; it varies greatly 

 in size and shape. 



Carya Buckleyi var. arkansana f. pachylemma Sarg. The type tree of 

 this form was found growing on a bench between the uplands and low 

 bottoms a short distance from Fulton. Although the nut itself is not as 

 large as in some forms of C. laciniosa the very thick involucre makes it 

 perhaps the largest-fruited of the Hickories. 



MYRICACEAE 

 Myrica cerifera L. Growing in low sandy woods and margins of bogs. 



SALICACEAE 



Salix nigra Marsh. Often very common in low woods and along streams. 

 Salix nigra var. altissima Sarg. Large specimens of the tall Black 

 Willow are common on the banks of Red River and in the low woods. 

 Salix longifolia Muhl. Growing along bayous and banks of streams. 



«f< 



Some very large 



specimens of this Cottonwood are found on the banks of Red River, and 

 it is also often common in low woods.
