The wonderful ipes of Brasilia are in full bloom despite the severe dryness. A native tree of the cerrado region of Brazil, these trees lose all of their leaves as winter approaches and then have flowers that explode in bursts of bright yellow. It's actually quite amazing and wonderful to behold.
I recently took a picture with my cell phone (hence the low quality) of a small ipe tree in bloom near my house when I was out walking. I will try to take more pictures of the much bigger trees and post them here soon.
