Arachis Jii/pogcea, L. Besides the importance of this 

 plant to the cultivator in hot countries on account of its 

 oily seeds, it is particularly interesting to the naturalist,

 legununous plants of similar appearances, by which the 

 seed is in a manner changed into a bulb ; for example, in

 suhterraneum, Glycine subterranea, monoica, and hetorocarpa,

 the Milium amphicarpum, Pursh.
