 terminal cymes on short lateral spurs; calyx 5 lobed, acuminate; petals 

 obtuse, contracted to a stalk-like base, white or pink; stamens usually

Malus malus (L.) Britton (Pyrus malus Linnssus) {Malus sylvestin 

 Miller) of uncertain origin is the parent of the common cultivated apple. 

 The genus is very important both for its commercial value as well as for 

 its ornamental value. Malus is characterized by a flower with an open 

 calyx, with a style connate at the base and by a fruit with a depression 

 at either end. No case of hybridizing between Malus and Pyrus is known. 



Malus baccata Borkhausen. 

 Wild Apple. 



Small tree. Leaves ovate to ovate-lanceolate," acuminate, thin, 

 glabrous, finely and irregularly serrate, bright green at the time of 

 opening. Flowers white on slender green pedicels. Styles usually 5, 

 longer than the stamens; calyx lobes lanceolate to acuminate, commonly 

 deciduous as fruit matures. Fruit very small, reddish-yellow, 2 cm. or 

 less in diameter. 



Mongolia, Siberia, Manchuria to Chihli and Shensi. 



A hardy ornamental species with handsome white flowers which 

 appear with the leaves. The fruits are red or yellow, translucent and 

 never become mellow, remaining on the tree a long time after they are

 should be worthy of extensive cultivation.
