Back in March when the Cojoba tree was in bloom, I was eager to see the beans. Panamanians call the tree coralillo, meaning “coral snake,” and it’s the beans that have two of the three coral snake colors – red and black (yellow is the third coral snake color). Further, the colors are bright, just like the colors of the coral snake.
Hi-res
Now the beans are here. They started appearing a few weeks back, but there was one bean here, another way over there in another tree. Now there are several beans in each tree, but still the beans are scattered lightly and are not as strikingly visible from a distance as you might think from their colors.
Look at how the beans are still attached to the pod, even though they’re not within the pod itself. This appearance might be a way of luring birds to the tree to disperse the seeds (Zuchowski) although few birds seem to be attracted to these beans. All members of the bean family have complex seed coats, but the coats of these beans are actually simpler in anatomy than that in other beans. They are called “overgrown” or “overgrown-like” beans and the value or function of this feature is not yet known (Maumont).
If you click on the left image below, you’ll see some more dangling beans, whereas the pod has not yet opened in the image on the right.


Family: Fabaceae (bean family – alternate compound leaves)
Subfamily: Mimosoideae (mimosa subfamily – the flowers have many stamens)
Tribe: Ingeae (from Inga, the ice cream bean)
Genus: Cojoba (the Taino Indian word for the leaves)
Species: rufescens (becoming red)
More on this tree at the original post.
Update:
Our gardener found a young coral snake in the weeds along the fence. He killed it with his machete and then brought the decapitated corpse for to us to see. It doesn’t have any yellow on it at all – its colors are simply red and black, as in the Cojoba bean. I don’t know what species this snake is – wikipedia lists three genera and many, many species for coral snakes. But here it is for your viewing pleasure:

PS – The species is probably Micrurus multifasciatus, a coral snake of two colors and the most common in Panama. Information from Panamá: Puente Biológio [Panama: Biological Bridge], by Stanley Heckadon-Moreno.
