Cycads on the edge

History of Cycads The genus Cycas is considered as one of the primitive plant groups (having naked seeds) and is botanically classified under Gymnosperms, existing for about 300 million years. All the members of the order Cycadales are commonly and collectively called Cycads.

The Giant Panda – least we forget

The Giant Panda – least we forget

What is happening to the giant panda? For my entire life the giant panda (Ailuropoda melanoleuca) has been on the endangered species list.
