Summary
[edit]| Description |
Transverse banding on a spine from a fishhook barrel cactus growing in Tucson, Arizona. Each band (1 couplet of thick white and thin red lines) represents one day of spine growth. The most recently grown tissue is at the thick, reddish base (right side in this picture) of the spines. Similar transverse banding is found in the spines of other cactus species as well, most notably saguaro cactus. Each square in the bottom scale = 1 centimeter. |
