 Indiana has led in the production of sycamore lumber for years. 



The sycamore is well adapted for shade, ornamental and forestry 

 purposes. It transplants easily, grows rapidly, stands pruning well 

 and is comparatively free from injurious insects. It grows straight, 

 tall and usually with a rather narrow crown. It prefers a moist soil, 

 but adapts itself to dry situations. For planting overflow lands, or 

 on the banks of streams it is one of the best species we have. It is 

 also one of the best species for roadside tree planting, because it is 

 deep rooted, grows tall, and does not produce a dense shade. 



MALlCEAE. 1 THE APPLE FAMILY. 



The trees of this family that occur in our area have simple, alternate 

 leaves; perfect, regular flowers, 5-merous calyx and corolla; fruit a more 

 or less fleshy pome. 



Flowers in racemes, cavities of mature fruit twice as many as 



the styles, seeds less than 4 mm. ( y% inch) long 2 Amelanchier. 



Flowers in cymes or corymbs, cavities of mature fruit as many 

 as the styles, seeds more than 4 mm. (J/g inch) long. 



Fruit green, mature carpels papery 1 Malus. 



Fruit red, orange, blue-black or yellow, mature carpels 



bony 3 Crataegus. 



I. MlLUS. THE APPLES. 



Malus angustifolia has been reported from the State, but it is a 

 species of more southern range. Both Malus ioensis and Malus land- 

 folia may easily be mistaken for this species. 



Leaves and petioles glabrous or only slightly pubescent; calyx 

 tube and outside of calyx lobes glabrous or only slightly 

 pubescent. 

 Leaves distinctly lobed, at least those of vigorous shoots; 



petioles pubescent above 1 M. glaucescens. 



Leaves serrate, not lobed; petioles glabrous 2 M. lancifolia. 



Leaves (at least the lower surfaces) and petioles densely to- 



mentose; calyx lobes densely tomentose on both sides. . . 3 M. ionesis.
