Anleit._ 162. 1825. =3.= Dochnahl _Führ. Obstkunde_ =3=:44. 1858. =4.= _Ill. Handb._ 145 fig., 146. 1860. _Bigarreau jaune de Dönissen._ =5.= Mortillet _Le Cerisier_ =2=:304. 1866. This variety is a seedling from Guben, Prussia, Germany, named for the originator; it fruited first about 1824. Tree vigorous, productive; fruit attached in twos, sometimes threes, large, roundish-cordate; suture slight; stem long, rather stout; cavity broad, shallow; skin glossy, transparent, yellowish-orange when ripe; flesh whitish, firm, slightly fibrous, moderately juicy, sugary, pleasingly acidulated; first quality; pit large, ovoid, plump; ripens the last of June to the first of July. =Bigarreau Doré.= _P. avium._ =1.= Thomas _Guide Prat._ 22. 1876. =2.= _Guide Prat._ 15. 1895. Fruit yellow, round. =Bigarreau Double Royale.= _P. avium._ =1.= Leroy _Dict. Pom._ =5=:195 fig., 196. 1877. _Königliche Fleischkirsche._ =2.= Dochnahl _Führ. Obstkunde_ =3=:34. 1858. _Königliche Herzkirsche._ =3.= _Ill. Handb._ 467 fig., 468. 1861. _Guigne Royale._ =4.= Mortillet _Le Cerisier_ =2=:301. 1866. The fact that Oberdieck received this variety from the Société Horticole de Prague under the French name Double Royale leads us to believe, as does Leroy, that it is of French rather than of Austrian origin as many German writers hold. Tree vigorous; fruit usually borne in pairs, large, cordate, rather abrupt at the ends; stem long, slender; cavity shallow; suture almost indistinct; skin glossy, reddish-brown to nearly black; flesh moderately tender, red, juicy, vinous, sweet; quality very good; pit small, ovoid, turgid; ripens about the middle of June. =Bigarreau Dur.= _P. avium._ =1.= _Lond. Hort. Soc. Cat._ 46. 1831. Listed in this reference without description. =Bigarreau Duranno.= _P. avium._ =1.= Leroy _Dict. Pom._ =5=:191. 1877. This variety is first mentioned by Leroy in 1868, appearing in his catalog of 1875 incorrectly as Bigarreau Duracino. The trees are used for stocks. Fruit large, roundish-cordate, uneven; suture narrow; stem long, slender; skin deep red in the sun; flesh firm, dry, acidulated, sugary; matures early in July.
