Ready for a Latin Lesson?

Since my life is so important and exciting, I started a blog. And just to prove how exciting and important my life is, I must inform all yall I have an exam tonight for Plant Pathology 309: Diseases of trees and woody ornamentals. I know, I know...you're life feels so much more complete knowing this vital fact about my life as a PlantPath Girl. Sorry for not telling you this sooner; I won't leave you hanging like that ever again. Promise.

Before I teach you Latin, here are some pictures I took. Relax your brain before it gets stressed!




Anyways, who's ready for a Latin lesson? I'm going to give you a list of every disease I have to know for my exam tonight; first in Latin and then the English common name. Ready? If it hurts your head reading it, it's okay. Just think of me who has to know how to pronounce them, how to spell them correctly, how to identify them, and distinguish them from similar diseases. Just another way to prove how exciting and important my life is. Wow, I'm so cool.


Do you know how hard it is to capture a picture like this. It took me over 50 times for the bee to land, stay there, my camera to snap the picture and for it to turn out beautiful.

Ready? Make sure you're sitting before you start this. My apologies if your mind explodes after 10 of these. Mine did too the first time I saw a name like this.

Hey, at least it was a really good review for me :)  Sorry if anyone has a stress headache from trying to make sense of the fancy schmancy words above!

Here's the video (of course it has nature in it!)
