Another Psychotria

I'm not sure if the P. viridis, described as chacrona in an earlier post, can be found at Bosque Santa Lucia. I do know that we have other species of Psychotria, as the one depicted in the image. They are quite prominent during the rainy season but disappear during the dry season of the year. The common name in Portuguese is "mata-gado", which translates into "kill-the-cattle". Evidently, the leaves are quite poisonous and ranchers make it a point to eradicate the plant from their pasture lands.
