CHAPTER IV. 

 Flowers and Fruit. 



THE author hopes that those who use this work in 

 studying trees will become so much interested in the 

 subject of Botany as to desire more information concern- 

 ing the growth and reproduction of plants than can here 

 be given. In Professor Asa Gray's numerous works the 

 additional information desired may be obtained : " How 

 Plants Grow " contains an outline for the use of begin- 

 ners; "The Elements of Botany" is a more advanced 

 work ; while the " Botanical Text Book," in several vol- 

 umes, will enable the student to pursue the subject as far 

 as he may wish. In this small book the barest outline of 

 the parts of flowers and fruit and of their uses can be 

 given. 



FLOWERS. Parts. The flowers of the Cherry or Apple 

 Trill show the four kinds of organs that belong to a com- 

 plete flower. Fig. 9 represents an Apple-blossom. The ca- 

 lyx is the outer row of leaves, 

 more or less united into one 

 piece. The corolla is the row 

 of leaves within the calyx ; it 

 is usually the brightest and 

 most conspicuous part of the 

 flower. The stamens ,;. : J5 are 

 the next organs; they are 

 usually, as in this case, small 

 two-lobed bodies on slender, 

 thread-like stalks. The en- 

 larged parts contain a dust- 

 Fig. 9. like material called pollen.
