Erythroxylum echinodendron
Erythroxylum echinodendron was endemic to Cuba and was declared extinct in the wild in 1998. Echinodendron means “spiny tree,” and you can see where it got its name in this herbarium specimen. Erythroxylum is a tropical genus with about 250 species.
While this particular species was declared extinct in the wild rather than extinct, this damaged herbarium specimen is the only record I could find of Erythroxlym echinodendron. There don’t seem to be any reintroduction projects in place or even specimens being studied in botanical gardens.
This is particularly sad since many Erythroxylum species are hosts for butterfly and moth larvae and some have powerful alkaloid compounds. Not only are we probably losing insect species with the loss of this plant, but we’ve lost a plant that could have contained chemicals for new medications.
While you may have never heard the word “Erythroxylum,” a large number of your tax dollars are spent trying to control a particular species in this genus. You may have even used a product of Erythroxylum coca.
While most people wouldn’t recognize this shrub,
Erythroxylum coca
everyone knows what it’s most valuable product looks like:
Our use of coal is very, very bad for the environment and everything in it - including us. While we won’t stop using coal anytime soon, we can decrease the damage it does with stronger regulations. Write a letter.

Gregory Boyce is skeptical of global climate change and has big plans for coal.
Despite the fact that coal is known to be one of the biggest sources of greenhouse gases, Boyce, 52, is banking on a future in which America burns a lot more of it. With the country’s huge reserves, he argues, coal should be doing much more than its traditional tasks of making electricity or steel. “We’re moving into an era where we’ll be driving our vehicles based on coal-derived fuel. We’re going to be flying on it,” Boyce declares.
It would be great to dismiss that as the ravings of a madman, but if we don’t start making better choices about the way we live and invest more in green technology, he could be right.
even in our iPod age, coal still sits at the heart of the economy. The Energy Dept. predicts overall electricity demand will grow by 45% between now and 2030. It also forecasts that coal-fired plants, today 51% of the market, will grow to 57% over the same period. Coal is cheap and plentiful. And there aren’t a lot of easy alternatives for replacing it anytime soon. Just to maintain nuclear power’s 20% of the U.S. energy market, 35 to 40 new plants will have to built in the next 20 years. Renewable sources such as hydropower, wind, and biofuels face similar challenges scaling up to meet market demand.
