Richmond. Mentioned in the United States Department of Agriculture Report, 1875, as being a very early southern grape.
Riehl’s Seedlings. Seedlings originated by E. H. Riehl, of Alton, Illinois. Those tested at this Station all show unmistakable traces of Concord blood and are presumably seedlings of that variety. The most promising of these is Eclipse, for a description of which see page 254. With the exception of Eclipse, none of his seedlings has been named or introduced.
Riesenblatt. (Aest.) Giant Leaf. A chance seedling found growing in the vineyard of M. Poeschel at Hermann, Missouri. Hardy, healthy, productive; with a very large leaf; bunch and berries small.
Roanoke Red. (Cord. Lab. Vin.) From Texas, previous to 1900. Very vigorous; stamens upright; bunch medium, moderately compact; berry medium, reddish-purple; fair to good; ripens with Pocklington.
Robert Wylie. Produced by Dr. A. P. Wylie, Chester, South Carolina. Described in Bushberg Catalogue, 1883, as a great bearer but not quite hardy; bunch large and long; berry large, blue; skin thin; rich and juicy; ripens as late as Catawba.
Robeson. From a Mr. Robeson, of South Texas. Resembles Devereaux; probably a seedling of that variety but inferior to it in every respect.
Robeson Seedling. According to the Bushberg Catalogue, 1894, identical with Louisiana. Probably the same as Robeson.
Robinson Unnamed Seedling. (Lab.) Given in Bushberg Catalogue, 1894, as an accidental seedling found by Mrs. E. Mason, Lamont, Michigan, in 1881. Moderate grower with Labrusca foliage; bunch medium, round, reddish-amber with thin whitish bloom; pulp tender, juicy, vinous, sprightly, a little foxy, “very good”; ripens with Delaware.
Robusta. (Long.) A variety of Vitis longii found in Motley County, Texas, and used by Munson. Cluster small; berry small; self-sterile; ripens early.
Rockingham. (Lab.) A seedling of Concord; from T. B. Miner, of New Jersey. Described by Mitzky, 1893, as “hardy, vigorous, productive; bunch and berry medium, black; quality like Concord.”
