 horticulturist, Central Experimental Farm,

As grafting will, in all probaoility, become 

 much more general among fruit growers in 

 the near future, the importance of knowing 



that trees vary widely in productiveness Js 

 easily seen. If the fruiting habit is con- 

 tinued in the grafted scion, as has been fair- 

 ly proven by experimenters, it is most im- 

 portant that scions should be taken from he 

 most productive trees bearing the finest fruit. 



PLANT STUDY— TERMS EVERYONE SHOULD KNOW. 



W. CLEMONT MOORE. 



A KNOWLEDGE of some 

 of some of the the terms 

 usod by botanists, and why 

 they use them, we are sure 

 cannot but prove beneficial to 

 all of those who are beginners 

 in the art of floriculture, hence 

 we proffer the following lesson 

 on some of the parts of the 

 plants, which should first be 

 considered. 



Cryptogams — Plants which 

 do not bear flowers. Fig. i 

 represents a cryptogamous 

 leaf. 



Phanerograins—V\iAX\ts which 

 bear flowers. This class of 

 plants presents a wide and 

 varied collection. Fig. 2. 



Embryo — The beginning of 

 plant. Fig. 3. 



Fibrous Roots — Are those 

 which send out fine rootlets, 

 but have no main stem. Fig. 

 4. Fleshy roots are principally 

 biennials, that is, they com- 

 plete their growth in two years. 

 Fig. 5- 



Exogenous — Applied to stems whose 

 wood fibres are in regular circles around a 

 central pith. Fig. 6. 



Endogenous — Stems whose wood fibres 

 are arranged irregularly through the stem

instead of the form of a circle. Fig. 7. 

 Net-veined and parallel-viewed leaves are 

 shown in Figs. 8 and 9 respectively. 



Calyx is the small circle or cup which 

 holds the flower. Fig. 10.
