38<3 GLOSSARY. 



Pinnule. A secondary leaflet in a pinnately decompound leaf, 

 (e. g. Honey Locust.) 



Pistil. The part of the flower bearing the ovules and which 

 ripens into the fruit. 



Pistillate. Bearing pistils but no fertile stamens. Often used 

 synonymously with female. 



Placenta. Place of attachment of ovules in an ovary. 



Pollen. Small spores produced by the anthers for the fertiliza- 

 tion of the ovules. 



Pollination. The carrying of pollen from the anther to the 

 stigma. 



Polygamous. Perfect and unisexual flowers borne on the same 

 plant. 



Pome. Fruit represented by the Apple, Thorn, Quince, etc. 



Propagation. The multiplication of plants. 



Pruning. The removing of branches from a plant to improve its 

 general appearance or to check or encourage growth. 



Pubescent. Covered with fine short hairs. 



Quarter sawing. The sawing on the radius, but as it is not prac- 

 ticable to do this exactly, the log is first quartered and 

 then sawed into boards, cutting them alternately from 

 each face of the quarter of the log. Sawed in this way the 

 grain of the wood does not show nearly so conspicuously 

 and varied as in that tangentially sawed, but the grain is 

 narrower, and the wood sawed in this way does not warp 

 nearly so much as that tangentially sawed, and is much 

 more expensive. (Page 168.) 



Raceme. A simple inflorescence in which the flowers are on 

 pedicels, and the lower open first, (e. g. Black Cherry, 

 page 324.) 



Ranging poles. Straight poles about eight feet long used by sur- 

 veyors to indicate the direction of a line which is being 

 measured or the position of points to be located. 



Regular. Parts of each cycle of the perianth alike, (e. g. Bird 

 Cherry.) 



Root. A part of the plant which absorbs nourishment for the 

 plant, or serves as a support. It may be underground or 

 aerial. 



Root-cutting. See cutting. (Page 86.)
