Burke: Pinus longaeva vs. Pinus albicaulis

	Pinus longaeva	Pinus albicaulis
		white-bark pine
Habit		Usually a dwarf and contorted alpine tree 5-15 m. tall.
Bark		Bark thin with whitish scales that are brownish underneath; young twigs pubescent.
Leaves		Leaves in bundles of 5, yellow-green, 4-7 cm. long, somewhat curved, on spur branches that are ultimately deciduous with the needles.
