«' Formerly the species now included in the genus ^falus (apples) were combined with the pears under 

 the genus Pyrus (pears) . 



« Alfred Rehder (in Sargent, Trees and Shrubs, II, Pt. IV, 229, 1913) believes that the Narrow-leafed 

 Crab, Pyrus angustifolia \\ion=Malus angustifolia (Aiton) Michaux, is the same as Pyrus coronaria Lin- 

 naaeus, the name which has long been applied to the Sweet Crab. Accordingly, he would restor-e Pyrus 

 coronaria Linnaeus=-\/afris coronaria (Linnaeus) Miller, to the Xarrow-leafed Crab. A form with slender 

 pendulous branches is distinguished as Malus angustifolia Rehder.
