i 2 \ntive Trees of Kentucky 



A. PINES GENUS PINUS. 



Kentucky is in the center of the most productive hard wood 

 region of the world, and as a State, can not claim a large com- 

 mercial supply of Pines. There are four native species in the 



State : 



a. Short-leaf Pine Pinus echinata. 



b. White Pine Pinus strobus. 



c. Pitch Pine Pinus rigida. 



d. Scrub Pine Pinus virginiana. 



They all have a characteristic method of growth, a tall, con- 

 tinuous, tapering shaft and branches arranged in horizontal layers 

 of imperfect whorls. The leaves are of two kinds, primary and 

 secondary : primary small, scale-like, forming a sheathe, falling 

 early ; secondary long, needle-like, persistent in clusters of two 

 to five. The flowers are of two kinds, staminate and pistillate, 

 arranged in small catkins on different parts of the same tree. 



The fruit, a woody cone of variously shaped scales, matures 

 usually at the end of the second season. These cones often per- 

 sist for many years, but shed the seeds at maturity. The seeds, 

 usually winged, are borne in pairs at the base of the cone scales.
