Forms
There are two Pinus muricata forms:
- a southern form with bright green needles
- a northern form with dark blue-green needles.
The resin composition also differs. The dividing line between the two is very sharp, five miles (8 km) south of the boundary between Mendocino County and Sonoma County, California. Experimental attempts to hybridize the two forms have consistently failed, indicating that their taxonomic relationship may be more distant than the very small differences in appearance would suggest.

Famous quotes containing the word forms:
“Culture’s essential service to a religion is to destroy intellectual idolatry, the recurrent tendency in religion to replace the object of its worship with its present understanding and forms of approach to that object.”
—Northrop Frye (b. 1912)
“This is a catastrophic universe, always; and subject to sudden reversals, upheavals, changes, cataclysms, with joy never anything but the song of substance under pressure forced into new forms and shapes.”
—Doris Lessing (b. 1919)
“The Dada object reflected an ironic posture before the consecrated forms of art. The surrealist object differs significantly in this respect. It stands for a mysterious relationship with the outer world established by man’s sensibility in a way that involves concrete forms in projecting the artist’s inner model.”
—J.H. Matthews. “Object Lessons,” The Imagery of Surrealism, Syracuse University Press (1977)
