ROSACE AE . — PRUNUS 281 



Kwang-tung: Hongkong, a. 1885-86, E. Faber (distributed as P. japonica). 

 This species is remarkable in the fact that its solitary flowers are borne in the 

 axils of full grown leaves which resemble those of Prunus mume.

 Prunus mume var. Goethartiana Koehne, n. var. 



Folia ut in P. mume typica, majuscula, 6.5-10 cm. longa, 4-6.1 cm. lata, subtua

 mus, puberulo-velutinus; cupula 4.5 mm. longa, subsemiglobosa, extus puberulo- 

 velutina; sepala 5 mm. longa, reflexa, late ovata, acutiuscula v. obtusa, ciliolata 

 extus puberulo-velutina; petala 16 mm. longa, 10.5 mm. lata; stamina 37, majora 

 11 mm. longa; ovarium villoso-tomentosum ut styli pars dimidia inferior. 



Japan, Buerger. 



This variety I have named in compliment to Professor Goethart, who has kindly 

 sent me valuable material from the Rijks-Herbarium at Leyden. A form of Prunus 

 mume with completely pubescent cupula and pubescent sepals has not been 

 described before. 



I hope that the flowering and the leaf bearing branches belong together. This, 

 however, is not always the case in the older collections from Japan. 



The following Japanese garden forms have been distinguished. 

 Prunus mimie, var. typica Maximowicz. See p. 278.

Southeastern Mongolia, also in Dahuria. 



Armeniaca Davidiana Carriere in Rev. Hort. 1879, 236, fig. 46-48, seems to be 

 closely related to P. sibirica on account of the dehiscent epicarp and the smooth 

 stone, characters which Maximowicz emphasizes for P. sibirica. He attributes to 

 the latter "ramos patentes," while Armeniaca Davidiana has pendulous branches; 

 it is therefore possibly a pendulous form of P. sibirica. Carridre gives very gener- 

 ally China as the habitat of his Armeniaca Davidiana; if it should have come 

 from northern China, its range would be close to that of P. sibirica, which is 

 found in southeastern MongoUa and in Dahuria.

Pnmus Armeniaca, var. holosericea Batalin in Act. Hort. Petrop. XIV. 167 

 (1895). 



Eastern Tibet; between Litang and Batang, June 1, 1893, V. A. Kashkarov. 

 1 have not seen specimens of this variety. 



According to the observations which I have made on young cultivated plants 

 of the species of the section Armeniaca it seems hardly advisable to distinguish 

 varieties by the pubescence of the leaves (see footnote, p. 279).
