When I first posted the image of these flowers, I identified them as the genus Senna. I had mistakenly confused them with other yellow flowers in the immediate area, which had been identified by Mary at A Neotropical Savanna as Senna. Sorry for the confusion. Refer to our
exchange posted under comments. Back to the drawing board.

Hi Steven, Thanks for your kind mention of my blog. Sorry to disappoint, however, but this flower does not look like a Senna to me. I've never seen a Senna flower with a trumpet shape to it. This flower looks more like it belongs to the Tabebuia genus.

Compare the Senna here -

with the Tabebuia part way down the page here -

The Senna link points to my post and picture, and it contains a link back to your Senna photo (which is far superior to mine, by the way!).

The Tabebuia link is to a post about a couple of trees with yellow flowers. Normally our Tabebuia blooms in January, but the other day I thought I saw one in early bloom by the side of the road. It would not surprise me at all if your tree is a Tabebuia. They call them "oak" trees here, by the way, because of the good quality of the wood.

The old saying that "not all that is yellow is gold" comes to mind, as I read your comments. Looks like I goofed. I now see that the flowers I posted today are different than the ones you described as Senna in your blog. So I need to take a step back to review the flowers and trees. The flowers do look like Tabebuia, but the bark, size of tree and leaves don't match. Unless, another species. We have many older Tabebuia trees at the Bosque reserve. They bloom during the dry season and they lose all their leaves before the bloom. And I believe that they don't flower as seedlings. Anyway, thanks for the insight. Time for some research. I'll get back with you.

Hi Steven,
Yes, the Tabebuia here in Panama also bloom in the dry season and before their leaves return. Likewise, I'm pretty sure they don't bloom as seedlings. So...good luck at your drawing board. I'll be interested to see what you find!

The Tabebuia I mentioned at Bosque Santa Lucia are Tabebuia serratifolia, which gets to be a very large tree. I looked through the brush in which I saw these flowers, but I didn't find any of these species. No flowers either. The summer is a very long hot dry one with no rain in sight. The serratifolia species bloomed some weeks ago. Guess I have to wait for another season to get a fix on those trees.
