This cherry was named after Dr. Wiseman, Davie County, North Carolina, who claimed it to be the earliest Sweet Cherry. Van Lindley believes it to be the Doctor which originated with Professor Kirtland. Fruit of medium size, light yellow, shaded with bright red, resembling Wood. =Doctorkirsche.= _P. avium._ =1.= Christ _Obstbäume_ 161. 1791. =2.= Christ _Handb._ 674. 1797. =3.= Truchsess-Heim _Kirschensort_. 402-405. 1819. =4.= _Ill. Handb._ 497 fig., 498. 1861. This variety was first mentioned in 1791. It should not be confused with another sort mentioned by Büttner and Truchsess as Doctorknorpelkirsche. Fruit large, roundish, somewhat compressed; stem long; cavity rather deep; skin tough, brownish-red changing to reddish-black; flesh dark red, melting, juicy, sweet yet with a sprightly flavor; pit round, slightly pointed; ripens the middle of July. =Doctorknorpelkirsche.= _P. avium._ =1.= Truchsess-Heim _Kirschensort_. 201, 202, 203. 1819. =2.= Dochnahl _Führ. Obstkunde_ =3=:37. 1858. According to Truchsess, this sort was received by him in 1797, from Büttner at Leipzig under the name of Doctorkirsche. Because one or two other sorts were growing at that time under this name, Christ changed this one, following Büttner's description, to Doctorkirsche mit Hartem Fleisch, which has since been shortened to Doctorknorpelkirsche. Fruit large, slightly compressed; stem long and slender; color black; flesh firm, clear red, juicy, agreeably sweet; ripens the middle of August. =Dollaner Schwarze.= _P. avium._ =1.= _Ill. Handb._ 9 fig., 10. 1867. According to Oberdieck, this variety originated at Dollan, Bohemia, Austria, the home of the Dollaner prune. Fruit above medium in size, truncate-cordate, traversed entirely by a suture; stem slender, long, set in a narrow, shallow cavity; skin tough, brownish-black with light spots, wholly black when ripe; flesh and juice dark red, flesh firm, but tender enough to be classed among the Hearts, sweet, aromatic, with a slight sourness before fully ripe; stone elongated-oval; season late. =Donna Maria.= _P. cerasus._ =1.= Barry _Fr. Garden_ 326. 1851. =2.= _Am. Pom. Soc. Cat._ 74. 1862. =3.= _Am. Hort. An._ 84 fig. 41, 85. 1869. This is a Morello cherry, probably of French origin. It is distinct from the Early May grown in the West with which it has been confused. Donna Maria held a place on the American Pomological Society's catalog of fruits from 1862 until 1899. Tree small, productive; fruit medium in size, roundish, dark red; flesh tender, juicy, sprightly; good in quality; season late. =Doppelte Weichsel.= _P. cerasus._ =1.= Christ _Handb._ 673. 1797. =2.= Truchsess-Heim _Kirschensort_. 505, 506, 507. 1819. _Doppelte Amarelle._ =3.= Christ _Obstbäume_ 158. 1791.
