Common Name: PINE FAMILY Habit: Shrub, tree, evergreen; monoecious. Stem: young crown conic; twig not grooved, resinous, generally persistent. Leaf: simple, generally alternate, sometimes in bundles or appearing +- 2-ranked, linear or awl-like; base decurrent, woody or not, persistent several years. Pollen Cone: generally < 6 cm, not woody, deciduous. Seed Cone: generally woody; bracts, scales generally persistent; scale not peltate, fused to or free from subtending bract. Seed: 2, on scale base adaxially. Genera In Family: 10 genera, 193 species: generally northern hemisphere; many of great commercial value, supplying > 1/2 of world's timber. eFlora Treatment Author: J. Robert Haller, Nancy J.

NATIVE Stem: trunk < 61 m, < 2.7 m wide; mature crown rounded; bark white-gray in youth, gray-brown to +- black, thick, deep-furrowed, with alternate dark, light layers in age; twig glabrous; bud resinous. Leaf: +- 2-ranked on lower branches, twisted upward on higher, 3--9 cm, +- flat; adaxial +- white bands 0; tip generally blunt or acute. Seed Cone: 7--13 cm; stalk < 5 mm; bract included. Ecology: Mixed-conifer to lower red-fir forest; Elevation: 900--3100 m. Bioregional Distribution: KR, NCoR, CaRH, SNH, Teh, TR, PR, MP, n SNE, DMtns; Distribution Outside California: to central Oregon, Idaho, Colorado, northern Baja California. Note: Further study needed: most California, some Rocky Mountains plants would be called Abies concolor var. lowiana (Gordon) Lemmon were that taxon recognized; relationship of southern California plants (especially from DMtns) to generally Rocky Mtns Abies concolor var. concolor.

MAP CONTROLS 1. You can change the display of the base map layer control box in the upper right-hand corner.
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 occurrence).
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.
