The typical form of M. baccata seems to be a more northern form than the var. 

 mandshurica; it ranges from Mandshuria and Chili through Mongolia and Siberia 

 to Shensi; farther south it is replaced by var. mandshurica and in the western 

 Himalaya by var. himalaica Schneider of which I have seen Falconer's No. 393 

 from Gurhwal, which differs from the type in its more coarsely serrate leaves. 



Malus baccata, f. Jackii Rehder, n. f. 



A typo recedit foliis majoribus ellipticis ad 12 cm. longis et ad 6.5 latis, floribus 

 majoribus circiter 3.5 cm. diam., fructibus intense rubris circiter 1 cm. diam. 



Korea: Seoul, September 22, 1905, J.G. Jack. Cultivated at the Arnold Ar- 

 boretum. 



This is a very handsome form with large pure white flowers, large dark green 

 leaves and large dark red fruits. The leaves are quite glabrous on their underside, 

 but on their upper surface they are coated, when unfolding, with a thin floccose 

 tomentum which quickly disappears; at maturity they are of firm texture and 

 glaucescent below. In general appearance this form resembles var. mandshurica, 

 but it is quite glabrous.
