386 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.

Propagation. The multiplication of plants. 
Pruning. The removing of branches from a plant to improve its 
general appearance or to check or encourage growth.

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.)

pedicels, and the lower open first. (e. g. Black Cherry, 
page 324.)

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.
