Lytro Light Field Photography at the 2013 Orchid Show

I received the Lytro camera yesterday at the William and Lynda Steere Herbarium. I am interested in using it for photographing plant specimens that require broad depth of field, but I could not resist giving it a test drive at the 2013 Orchid Show.

The Tree That Ate Houston

Fascinating and scary essay from Harvey Cotten of the Huntsville Botanical Garden on Triadica sebifera, also known as the Chinese tallow tree, the popcorn tree, the Florida aspen, and the chicken tree (and previously known as Sapium sebiferum). Regardless of what you call it, Triadica sebifera is highly invasive, and for many years it’s introduction to the United States has been placed squarely on the shoulders of Benjamin Franklin! But modern genetic testing has vindicated Franklin, and the mystery of this nuisance tree’s arrival (and domination) of the southern United States remains a mystery.

Highly Invasive Horse-Chestnut Leaf Miner Found Living in the Balkans by 1879

We are sometimes asked why herbariums are important. This article tracing the evolution of a highly destructive insect pest through herbaria specimens is a perfect example of why we should continue to support the collection and cataloging of botanical specimens.

Generations of scientists and amateur wildlife enthusiasts have  collected plants, fungi, and algae and mounted them onto sheets of paper  to preserve them. Many of these sheets now  serve as historical records in vast archives called herbaria. Some  herbaria hold specimens gathered more than 200 years ago; most started  with the personal collection of one dedicated person who amassed  thousands of plants. Carl Linnaeus, the 18th-century botanist  who created the scientific naming system of species we use today,  collected 14,300 specimens that are still kept in The Linnean Society of  London’s herbarium.
