PRACTICAL COURSE IN BOTANY 



PLATE 5. Stem of a conifer, Sequoia gigantea, Mariposa Grove, California. The 

 first branch, 6 feet in diameter, leaves the parent trunk 125 feet above the ground. 

 The photographer sitting on one of the exposed roots affords a good standard for 

 comparison. The tree is noted for its massive limbs. The smaller trees in the 

 background show the characteristic mode of branching in trees of this class.
