Chappellier. The tnbers are dob shaped, tapering to a finger size at the 

 iqqper i»art, and when grown in the open are generally about 9 to 10 inches 

 iDDg and w^h 12 to 14 ounces when folly grown. Occasionally twin tubers 

 derelop on a single plant, bnt they are then of medium size. This yam may

 multiplication is by bulbils. (Adapted from TJie Hardp Tarns, by Dr. H. E.
