Bamboo

 

I am fascinated by bamboo. My fascination dates back to when I lived in the jungle in Panama. There are over a 1000 different varieties of bamboo. Quoting from Wikipedia: List of bamboo species;

In the tribe Bambuseae also known as bamboo, there are 91 genera and over 1,000 species. The size of bamboo varies from small annuals to giant timber bamboo. Bamboo evolved only 30 to 40 million years ago, after the demise of the dinosaurs. Bamboo species can be divided into clumping (sympodial) and running (monopodial) species.

This photo is obviously clumping bamboo.
