The Woodi/ Plants of Kentucky. 29 



Sandalwood Family ( Santalaceae) . 



Oil Nut (Pijrularia pubera). — A straggling shrub occasionally 

 seen among undergrowth in mountain forests. 

 Bell, Harlan, l'owell. 



Mistletoe Family (Loranlhaceae). 



Mistletoe (Phoradendron flavescens). — A very common plant 

 parasite in most of the State. In Bluegrass Kentucky largely re- 

 stricted to black walnut, but occurring less often on black locust, 

 American elm and other trees. In Western Kentucky it is not so 

 closely confined to walnut. Exceptionally severe winters sometimes 

 destroy much of it, but it gradually reappears and becomes common 

 again. The fine green foliage and handsome translucent berries 

 render it a favorite for Christmas decorations, and it is often seen 

 in quantities in our market. 



The common blue bird (Sialia sialis) seems to be an important 

 agent in its dissemination. The greater part of the food of this 

 bird consists at times in midwinter of mistletoe berries. The 

 mucilaginous substance surrounding the seeds no doubt adheres to 

 its beak and is rubbed off on twigs and branches where on drying it 

 fastens some of the seeds down securely.
