Description
In spite of their broadly similar appearance, cycads
and palms are not close relatives.
Cycads were at their height in prehistoric times. Around 150 to 200 million
years ago, during the Jurassic Period, they were one of the dominant types
of plant life, growing in vast luxuriant jungles throughout the world.
There are now less than 200 species of cycad left and many of these are
rare.
Location
Their habitats range from cold,
arid deserts to warm,
tropical rainforests. Most cycads are tropical
or subtropical though a few are temperate and a very small number can
survive frosts.
Features
Most cycads are very slow-growing
plants (yes, even slower than palms!) and
they often take several years to develop any sign of a trunk. Some species,
in fact, never develop a visible trunk. In these species the trunk grows
below ground, leaving just the crown of leaves visible on the surface.
