Nevada State Tree

Singleleaf PinyonNevada State Tree: Singleleaf Pinyon

(Pinaceae Pinus monophylla )

Adopted in 1959.

See Bristlecone Pine

Nevada designated bristlecone pine (Pinus arisrata) as an official state tree in 1987; single-leaf pinon (Pinus monophylla) was the first tree symbol of Nevada, adopted in 1953. The Single-Leaf Pinon is an aromatic pine tree with short, stiff needles and gnarled branches.

The tree grows in coarse, rocky soils and rock crevices. Though its normal height is about 15 feet, the single-leaf pinon can grow as high as 50 feet under ideal conditions. Principal uses of the tree include fuel, fenceposts, Christmas trees, and edible seeds

Nevada State Tree: Singleleaf Pinyon

Singleleaf pinyon (Pinus monophylla), also called pinyon, nut pine, one-leaf pine, and piñon (Spanish), is a slow-growing, low, spreading tree that grows on dry, low mountain slopes of the Great Basin. One large tree near Reno, NV, is about 112 cm (44.2 in) in d.b.h., 16.2 m (53 ft) tall, and has a crown spread of about 20 m (66 ft).

Identification of the Singleleaf Pinyon

Pinus monophylla, (single-leaf pinyon), is a pine in the pinyon pine group, native to the United States and northwest Mexico. The range is in southernmost Idaho, western Utah, Arizona, southwest New Mexico, Nevada, eastern and southern California and northern Baja California.

  • Bark: is in old trees, thick, scaly, divided by longitudinal and horizontal furrows; in young trees thin and smooth.
  • Branchlets: light gray, rough, pubescent; bases of the leaf bracts are not decurrent.
  • Nevada State Tree: Singleleaf PinyonLeaves: in fascicles of 5, rarely 4, slightly curved, 1.5-4.0 cm long, 0.5-1.5 mm thick; margins entire, stomata primarily on the ventral surfaces with an occasional row on the dorsal surface; resin canals 2, rarely 1 or 3, dorsal; fibrovascular bundle single; the leaves bright green on the dorsal surface and silver-colored (lines of stomata) on the ventral surfaces; connate (united) during the first year. Sheaths of the leaves 5-9 mm long, curled into persistent rosettes, later deciduous.
  • Conelets: borne singly and in pairs on slender, short peduncles; globose with thick, transversely keeled scales.
  • Nevada State Tree: Singleleaf PinyonCones: subglobose; symmetrical; 3.5-5.0 cm long, 4.5-7.0 cm wide when open; yellow to ochre colored; dehiscent; deciduous when mature, the peduncle very small and falling with the cone.
  • Cone scales: few; the apophysis rhomboidal, transversely keeled; the umbo dorsal, flat to depressed, bearing a minute early deciduous prickle. Only the central scales are seed-bearing.
  • Seeds: brown; wingless; 14-17 mm long, 6-8 mm wide; the seed coat very thin, 0.2-0.3 mm thick; the endosperm white"
