Siskiyou cypress ( Cupressus bakeri )

The Siskiyou cypress ( Cupressus bakeri ), and Modoc cypress or cypress called Bakers, is a plant of the genus cypress (Cupressus ).

Occurrence

The Siskiyou cypress comes in the U.S. endemic in an area in Northern California ( Siskiyou County, Modoc County, Shasta County and Plumas County ), and in southwestern Oregon ( very isolated in Josephine County and Jackson County) ago. It usually grows in small, scattered populations, not in large forests at altitudes 900-2000 m.

Description

The Siskiyou cypress is a medium sized, evergreen tree with a conical crown. It reaches heights of growth of about 10 to 25 m, in exceptional cases up to 39 m and trunk diameter of usually 50 cm, in rare cases, 1 m. The scale-like leaves are dull gray-green to whitish blue-green, 2-5 mm long on rounded (not flattened ) branches.

The Siskiyou cypress is monoecious getrenntgeschlechtig ( monoecious ). The flowering period extends from February to March. Male pins are 3 to 5 mm long. The female cones are spherical to oval, 10-25 mm long, usually with six or eight (rarely four or ten) pin - shed, first green to brown, 20 to 24 months after pollination gray brown ausreifend. The cones often remain closed on the tree for several years, until the parent tree is killed by a bushfire. The seedlings can then on the bare ground well cast ( Pyrophyten ).

It is a slow growing tree and is therefore limited to areas where other plants can be difficult to gain a foothold, such as on serpentine soils or on cooled lava flows.
