The variety was first exhibited at a meeting of the Massachusetts Horticultural Society in 1870. It was originated by N. B. White, Norwood, Massachusetts, from seed of Marion fertilized with Black Hamburg. Bush questions this parentage owing to the fact that Amber Queen frequently shows continuous tendrils. In the vineyard of this Station, however, Marion shows continuous as well as intermittent tendrils, indicating that it would be quite possible for the Amber Queen to have inherited its aberrant tendrils from that source. Vine a strong grower, usually hardy, produces light crops except in favored locations, both leaves and fruit subject to attacks of fungal diseases. Leaves above medium size, roundish, rather thick. Flowers sterile or nearly so, practically incapable of setting fruit when self-fertilized, open about in mid-season and bloom a long time; stamens reflexed. Fruit variable in season of ripening, sometimes before, at other times after Concord, usually requires more than one picking to secure the fruit at its best, does not keep well as the berries soon wither. Clusters variable in size but not large, usually loose and open but sometimes compact. Berries not uniform in size, roundish to oval, dark red covered with more or less lilac bloom, somewhat resembling Catawba in color, not very firm as the berries soon shrivel, persistent. Flesh very juicy, soft and tender, mildly sweet at skin to acid at center, good to very good in quality. Seeds variable in size, frequently with enlarged neck; chalaza distinctly above center. AMBROSIA. (Labrusca, Vinifera.) =1.= _N. Y. Sta. An. Rpt._, =10=:494. 1891. =2.= _Ib._, =11=:614. 1892. =3.= _Ib._, =17=:526, 545, 547, 553. 1898. Ambrosia is a New York seedling which, though introduced nearly twenty years ago, has not found favor with grape-growers. In quality, while hardly worthy of its name, it ranks high and for this reason may be worth a place in the vineyard of the amateur. On the Station grounds it shells badly, differing in this respect from its supposed parent Salem. The variety was originated by Alfred Rose of Penn Yan, New York, from seed of Salem, planted in 1884. It was received for testing by this Station in 1888. There are no records of its having been tested elsewhere.
