Description and ecology
Vegetative characteristics
The Guadalupe cypress is an evergreen tree with heights of 10 to 20 meters. The treetop is conical to ovoid-conical. The scale-like leaves are dark green to gray-green, 2 to 5 mm long and arranged on rounded, not flattened branches.
Generative characteristics
The Guadalupe cypress is single sexed ( monoecious ). The flowering period extends from February to March. Male cones are 3 to 5 millimeters long. The female cones are spherical with a length of 25 to 35 millimeters, with six to ten cone scales. They are green at first and ripen to brown to gray-brown after 20 to 24 months after pollination . The cones stay closed for many years until the tree is killed by a bush fire ( pyrophytes ). Then the seedlings will find good growing conditions on the bare earth.
Occurrence
The Guadalupe cypress is endemic to the Mexican island of Guadalupe , which is part of Baja California. It grows at altitudes of 1000 to 1280 meters. The species is as endangered ( endangered classified).
