This is what I got to do this week!  Be sure to watch it so you can hear me say ‘poop’.

Science news! Also a mention of Linnaeus; he was the man. He was the father of taxonomy, an under-rated but important area of science.

This is Hibiscus cannabinus, commonly known as Kenaf. This common name comes from the fiber harvested from the plant, which is used to make paper. The fiber comes from the bark and wood and can also be used to make rope, twine and cloth.

This flower is in the Hibiscus genus, which is in the Malvaceae family. 

The flowers of all members of the Apiaceae family grow in umbels, shown here.

Shown here is a Silvereye bird on a Bottlebrush plant. Bottlebrush plants belong to the genus Callistermon, which is in the Melaleuca family. Members of this genus are native to Australia. 

Shown here are members of the Caryophyllaceae family, also known as the Pink family. They can be identified by their notched petals.
