Common Name: OAK FAMILY Habit: Shrub, tree, evergreen or not; monoecious. Leaf: simple, alternate, petioled; margin entire to lobed; stipules small, generally deciduous. Staminate Inflorescence: catkin or stiff spike, many-flowered. Pistillate Inflorescence: 1--few-flowered, generally above staminate inflorescence; involucre bracts many, generally overlapping, flat or cylindric. Staminate Flower: calyx generally 4--6-lobed, minute; petals 0; stamens 4--12+. Pistillate Flower: calyx generally 6-lobed, minute; petals 0; ovary inferior, style branches generally 3. Fruit: 1 nut subtended, partly enclosed by scaly, cup-like involucre or 1--3 nuts subtended, enclosed by spiny, bur-like involucre; mature years 1--2. Seed: generally 1. Genera In Family: 7 genera, +- 900 species: generally northern hemisphere. Note: Wood of Quercus critical for pre-20th century ship-building, charcoal for metallurgy; some now supply wood (Fagus, Quercus), cork (Quercus suber), food (Castanea, chestnut). Lithocarpus densiflorus moved to Notholithocarpus. eFlora Treatment Author: John M. Tucker, except as noted Scientific Editor: Thomas J. Rosatti, Bruce G. Baldwin.
Common Name: CHINQUAPIN Habit: Evergreen. Leaf: leathery, adaxially +- glabrous, green, abaxially golden, with densely spaced, minute, appressed scales, margin entire or +- wavy above middle; stipules generally deciduous. Staminate Inflorescence: branched or not, stiff, clustered or not, ascending to erect. Pistillate Inflorescence: clustered below staminate on same or separate stalk, 1--3-flowered. Staminate Flower: sepals generally 6, minute; stamens generally 8--10+. Fruit: nuts 1--3, enclosed by spiny, bur-like involucre, ovoid to +- spheric, +- angled; mature year 2.

2. County and Jepson Region polygons can be turned off and on using the check boxes.
(Note: any qualifiers in the taxon distribution description, such as 'northern', 'southern', 'adjacent' etc., are not reflected in the map above, and in some cases indication of a taxon in a subdivision is based on a single collection or author-verified occurence).

MAP LEGEND View all CCH records All markers link to CCH specimen records. The original determination is shown in the popup window.
Blue markers indicate specimens that map to one of the expected Jepson geographic subdivisions (see left map). Purple markers indicate specimens collected from a garden, greenhouse, or other non-wild location.
Yellow markers indicate records that may provide evidence for eFlora range revision or may have georeferencing or identification issues.
