McDonald’s Ann Arbor. (Lab.) Noted in the American Pomological Society Report for 1881. Berry very large, black with blue bloom; quality of Concord; ripens with Worden.
Macedonia. (Lab.) Miller’s No. 3. An early white seedling of Concord; raised by Samuel Miller of Calmdale, Pennsylvania, over fifty years ago. Said to resemble Martha but not so vigorous.

Not vigorous, usually hardy, moderately productive; tendrils continuous; leaves of medium size; clusters medium to large, usually single-shouldered, compact; berries large, oval, light green; skin tender; flesh tender, juicy, sweet; good; resembles Niagara but about ten days earlier.
McNeil. (Lab.? Rip.?) A variety resembling Clinton, cultivated in the Champlain region from fifty to seventy-five years ago.
Madeira. The name Madeira is common in the early grape literature of the country. Its use was begun at the time when many of the cultivated sorts were supposed to be of foreign origin. The significance of the word when found unqualified depends somewhat on the time and place. Thus, in the South, Madeira usually means Herbemont’s Madeira; in Ohio, Ives Madeira and in Pennsylvania, York Madeira.
