55. Vitis, n. sp. ? Abundant on the Arkansa. Fruit of 

 exquisite flavour, even superior, as stated by Dr. James, to 

 any other grape, native or exotic, which he had met with in 

 the United States. (See Long's Exped. vol. 2. page 126.) 

 The specimens of this plant, preserved in the herbarium, are 

 very imperfect, and are insufficient for the determination of 

 the species.
