NOTES AND COMMENTS 363 



are characterized by long, awl-shaped, spreading leaves in contrast 

 with the group of junipers which have small, scalelike leaves similar 

 to those of our Juniperus virginiana. Some measurements of growth 

 just received from Dr. George V. Perez, of Tenerife, are interesting. 

 The average height at the present time of trees planted in 1906, now 10 

 years old, is 30 2-3 feet, with diameters ranging from 3 to 6 inches. 

 The trees are planted in a close stand (6 to 8 feet part), which probably 

 accounts for the remarkable height growth and small diameter devel- 

 opment. The heartwood of this species is brownish, and has remark- 

 able durability, and it is believed that cultivation of the tree in this 

 country might be desirable for post timber. A small quantity of seed 

 recently obtained from Dr. Perez is to be given an experimental trial 

 in Florida and in southern California.
