I would appreciate help in accurately identifying these flowers. I recently traveled to Roatan Island and then La Ceiba mainland Honduras, photographing plants and hummingbirds. I realize the first is without the leaves so harder to identify, this one was cultivated. Second flower was growing wild at some elevation in forest. Commonly referred to as a "morning glory" by locals, but doesn't resemble exactly our Morning Glory in US. Thanks in advance for anyone who can help or point me in the right direction.
