Occurrence

The kind comes in the USA endemically in an area into north California (Siskiyou County, Modoc County, Shasta County and Plumas County) as well as in the southwest Oregon (much isolates in Josephine County and Jackson County) forwards. It usually grows in small, scattered populations, not in large forests in altitudes of 900 to 2000 m NN.

Description

The Zypresse is a medium sized, evergreen tree with a conical crown. It about 10 to 25 m, in exceptional cases to 39m highly, the master diameter reaches 50 cm, rarely to 1m

Leaves grow in lockernen, often hanging The sheets are matt grey-green to whitish cyan, shed-like, 2 to 5 mm long at roundish (not flattened) impulses.

The female taps are spherically to oval, 10 to 25 mm long, with 6 or 8 (rarely 4 or 10) Zapfen-Schuppen, first green to brown, 20 to 24 months after dusting grey-brown developing. The taps remain often several years closed at the tree, until the parents tree is killed by a shrub fire, which can drive seedlings out on the naked soil then well (Pyrophyten).

Male taps are 3 to 5 mm long. The bloom time is February March.

It is limited an slow-increasing tree and therefore to places, where other plants gain only heavily a foothold, as to Serpentin soils and on lava stream cooled off. Its tolerance against such locations avoids competition by much other trees.
