6. *Cupressus arizonica*

specimens from Natural Bridge where a grove occupies east slope of Pine Creek, occurs in small groups or groves on steep slopes of Mogollon Mesa rim. An area of 1000 acres to be found east of Pine, another large area near Payson.

Trees rarely over 60 feet, but diameter over 24 inches, hence stumpy looking; foliage grayish in appearance. In January (Febr. 11) "Smoky forest", poden flying? (Gowen). Lowbranched what I have seen, hence of little merchantable value. Bark is shed usually every year like in *Platanus* (gray & red patches) but not in old trees.
