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



The sycamore is well adapted for shade, ornamental and forestry 

 purposes. It transplants easUy, 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 ch\y 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. 



MALACEAE.i The Apple Family. 



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

 leaves; perfect, regulai' 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. (Jg inch) long 2 Amelanchier. 



Flowers in eymes or corj-mbs, cavities of mature fruit as many 

 as the styles, seeds more than 4 mm. (Jj inch) long. 



Fruit green, mature carpels papery 1 Malus. 



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



bony 3 Crataegus. 



I. MALUS. The Apples. 



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

 species of more southern range. Both Mains ioensis and Malus lanci- 

 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 these of vigorous shoots; 



petioles pubescent above 1 M. glaucescens. 



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



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



mentose; calvx lobes denselv tomentose on both sides. . . 3 M. ionesis.
