Fruit of medium size, obtuse-cordate; stem medium in length, set in a deep, straight cavity; skin purple, changing to almost black; flesh purple, rather tender, juice slightly colored, sweet; first quality; season the first of June. =Burghley Park.= _P. avium × P. cerasus._ =1.= _Flor. & Pom._ 229, 230. 1870. =2.= _Gard. Chron._ 1057. 1870. Burghley Park is a seedling, raised by R. Gilbert, Burghley Park, Stanford, England; it was placed on the list of new fruits of the Royal Horticultural Society in July, 1871. There is a question as to whether it is distinct, some believing it to be Reine Hortense. Fruit very large, usually oval, often flattened, with an obscure suture; stem long, rather slender; skin very thin, transparent, a brilliant dark red if left hanging; flesh dull yellowish-red, veined or netted, very juicy, melting, with a pleasing astringency; ripens in mid-season. =Burr.= _P. avium._ =1.= Cole _Am.

Tree vigorous, erect, round-topped, very productive, not always hardy; fruit medium to large, obtuse-cordate with a pointed apex; stem long, slender; skin thin, mottled with light and dark red; flesh whitish, rather tender, juicy, sprightly, agreeably sweet; very good in quality; stone small, irregularly ovate, short, thick; ripens in early mid-season. =Büttner Gelbe Knorpelkirsche.= _P. avium._ =1.= Truchsess-Heim _Kirschensort_. 361, 362, 363. 1819. =2.= Mortillet _Le Cerisier_ =2=:129, 130 fig. 31. 1866. =3.= Leroy _Dict.

Büttner, at Halle, Prussia, Germany, raised this cherry as a seedling and it is probably superior to any of the varieties originated by this horticulturist. It fruited for the first time about 1800 and was introduced shortly after. It was grown in America as Büttner's Yellow in the first half of the Nineteenth Century and was listed in the American Pomological Society's fruit catalog in 1875 but was dropped in 1899. Tree strong, vigorous, hardy, productive; fruit of medium size, roundish-cordate, flattened at the base; suture indistinct; stem thick, inserted in a broad, shallow cavity; skin firm, thick, pale yellow, slightly spotted with brownish-red; flesh pale yellow, firm, breaking, juicy, sweet, aromatic, with a rich, lively flavor; quality good; stone small, roundish-ovate, free; ripens early in July. =Büttner Rothe Herzkirsche.= _P. avium._ =1.= Truchsess-Heim _Kirschensort_. 236, 237. 1819. _Büttner's rothe Molkenkirsche._ =2.= Dochnahl _Führ.
