OregonFlora: Quercus arizonica vs. Fagaceae

	Quercus arizonica	Fagaceae
		beech family
Habit		Trees or shrubs evergreen or deciduous.
Buds		with several imbricate scales; terminal buds present.
Leaves		alternate; simple, pinnately veined, sometimes pinnately lobed; stipules present.
Inflorescences		spike-like catkins in leaf axils of current year, pistillate flowers near bases and staminate flowers above, or unisexual with staminate and pistillate inflorescences on same plant, or pistillate flowers solitary.
Flowers		radially symmetrical; sepals 4–6; free or basally fused; corollas absent.
Staminate flowers		stamens 6–many; free; pistillodes present.
Pistillate flowers		ovaries inferior, 3-locular; placentation axile; styles 3, linear or broadened distally; staminodes absent.
Fruits		large nuts, partly or completely enclosed in woody cups, with a spiny or scaly outer surface.

	Quercus arizonica	Fagaceae
Distribution	[WildflowerSearch map] [BONAP county map]	[BONAP county map]
Discussion		Throughout temperate northern hemisphere and mountains in northern tropics. 10 genera; 3 genera treated in Flora. Members of Fagaceae are dominant trees in parts of western Oregon. The nuts are large, rich in oils, and are an important food source for wildlife. The quality of the timber is high, but these hardwoods have never been important in the Oregon timber industry.
