According to Rochleder (ibid lxiii. 202), the tannic acid of black tea is the same as that of oak-bark. [7] In 1880, Etti gave for it the molecular formula C 17 H 16 O 9. He described it as an unstable substance, having a tendency to give off water to form anhydrides (called phlobaphenes), one of which is called oak-red (C 34 H 30 O 17). For ...

Mountains of southern Arizona and New Mexico such as the Santa Catalina Mountains and the Chiricahua Mountains, for example, have a pine-oak woodland at an elevation of roughly 1,710–2,160 m (5,700 to 7,200 ft). Here, Q. hypoleucoides can be found as well as other species of oak trees such as the Q. arizonica, Q. emoryi, and Q. rugosa. [11]
