Woody Plants Group 8

  1. 1. Woody Plants Group 8 • Pinus aristata • Pinus ponderosa • Pinus contorta var. • Pinus strobiformis latifolia • Pinus sylvestris • Pinus edulis • Pinus flexilis • Pinus nigra
  2. 2. Soft & Hard Pines • Soft pines have these features: • needles usually in bundles of 5, sometimes 4. • bundle sheath of needles is shed. • cones usually are up to 2quot; long and have a stalk. • scales on the cones are usually without prickles. • Hard pines have these features: • needles usually in bundles of 2 or 3; up to 8quot; or more. • bundle sheath persists (not shed after the first year). • cones often are over 2quot; long and usually without a stalk. • scales on the cones are usually thick, woody, and armed with prickles.
  3. 3. Pinus aristata Bristlecone Pine
  4. 4. • Typically small and contorted by the wind and harsh growing conditions, grows very slowly
  5. 5. Pinus aristata leaf • short (1 to 1 1/2 inches long), curved, fascicles of 5, dark green but usually covered with white dots of dried resin. Remain on tree for 10-17 years, giving a bushy appearance that resembles a fox's tail.
  6. 6. Pinus aristata flower • Monoecious; • male cones small, dark orange and often clustered near the ends of branches; • female cones occur singly or in pairs near the ends of branches. http://www.cnr.vt.edu/dendro/dendrology/syllabus/Paristata.htm
  7. 7. Pinus aristata seed • Moderate sized woody cone (about 3 inches long) • with a short stalk; • imbricate scales are thickened • and tipped with a long bristle, giving rise to its common name. • Seeds are winged.
  8. 8. Pinus aristata bark • Young bark is thin, smooth, and gray- white later becoming furrowed and reddish-brown. • Old trees on harsh, windy sites may have only a few strands of bark remaining in crevices where it is protected from sandblasting winds.
  9. 9. ID Pinus aristata • needles in 5's, tufted apperance • dwarf habit • white flecks on needles • Long thin ‘bristle’ at the end of each scale • retention of 17 years of needles

  28. 28. Pinus flexilis Flower • Monoecious; male cones are small and reddish; (csu – yellow) • female cones are bright reddish-purple http://www.colostate.edu/Depts/CoopEx t/4DMG/Trees/limber.htm
  29. 29. Pinus flexilis fruit • Moderate sized woody cone (3 to 6 inches long) with a short stalk. Imbricate scales are thick, blunt, slightly reflexed, and unarmed • Cones turn from green to brown as they ripen and scales open to release their seeds • Seeds are large and usually wingless.
  30. 30. Pinus flexilis bark • Initially thin, smooth and gray-white; later it darkens to brown or black with deep fissures and square plates
