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:
“The time will come when the evil forms we have known can no more be organized. Man’s culture can spare nothing, wants all material. He is to convert all impediments into instruments, all enemies into power.”

“One way to think about play, is as the process of finding new combinations for known things—combinations that may yield new forms of expression, new inventions, new discoveries, and new solutions....It’s exactly what children’s play seems to be about and explains why so many people have come to think that children’s play is so important a part of childhood—and beyond.”
—Fred Rogers (20th century)
“The method of authority will always govern the mass of mankind; and those who wield the various forms of organized force in the state will never be convinced that dangerous reasoning ought not to be suppressed in some way.”
