Locality Map



From Hollick (1930) (p. 51)

"Leaf 6.5 centimeters in length by 5 centimeters in width, oblong, with a cuneate base, a deeply emarginate apex, and a corrugated lamina; margin entire or wavy; midrib curved, conspicuously thick up to about the middle of the leaf, thence thinning out rather abruptly to the apex; nervation simple, spreading below, gradually becoming less and less divergent from the midrib above."



From Hollick (1930) (p. 51)

"This leaf apparently differs from any other described species of the genus in its greater width relative to length. It may possibly be a variety or form of Protophyllocladus polymorphus (Lesquereux) Berry, the species next described, but unless intermediate forms are discovered a specific differentiation appears to be justified."
