ROSACEAE. — 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, subtus

mus, puberulo-velutinus; cupula 4.5 mm. longa, subsemiglobosa, extus puberulo- 
velutina; sepala 5 mm. longa, reflexa, late ovata, acutiuscula v. obtusa, ciliolata

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.

Southeastern Mongolia, also in Dahuria. 
Armeniaca Davidiana Carriére in Rev. Hort. 1879, 230, 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. Carriére 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 Mongolia and in Dahuria.

ve 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).
