The Siskiyou cypress ( Cupressus bakeri , Syn .: Hesperocyparis bakeri (Jeps.) Bartel ), also called Modoc cypress or Baker's cypress , is a species of the genus cypress ( Cupressus ).
Occurrence
The Siskiyou Cypress comes in the USA endemic in an area in Northern California ( Siskiyou County , Modoc County , Shasta County and Plumas County ) and in southwestern Oregon (very few in Josephine County and Jackson County ) ago. It usually grows in small, dispersed populations, not in large forests, at altitudes of 900 to 2000 meters. It is a slow-growing tree and is therefore restricted to areas where other plants find it difficult to gain a foothold, such as on serpentine soils or on cooled lava flows.
description
The Siskiyou cypress is a medium-sized, evergreen tree with a cone-shaped crown. It reaches heights of growth of around 10 to 25 m, in exceptional cases up to 39 m and trunk diameters of mostly 50 cm, in rare cases 1 m. The scale-like leaves are matt gray-green to whitish blue-green, 2 to 5 mm long on rounded (not flattened) branches.
The Siskiyou cypress is single sexed ( monoecious ). The flowering period is February to March. Male cones are 3 to 5 mm long. The female cones are spherical to oval, 10 to 25 mm long, with usually six or eight (rarely four or ten) cone scales, initially green to brown, maturing to gray- brown 20 to 24 months after pollination . The cones often remain closed on the tree for several years until the parent tree is killed by a bush fire . The seedlings can then sprout well on the bare ground ( pyrophytes ).
