No, they are normally shrubs... but this is not a Hibiscus, not a Lavatera, not a Rubus and not a Ribes... :) P.S.: And that reddish something is NOT a leaf! :)
A Schefflera with so huge and reddish flower bract?! Hm... maybe Schefflera looks a bit different in Ecuador... :) But you are on the right way! It is a bract... but fruit bract...
The boulevard Shefflera down the street bloomed recently with huge red bracts, so anything's possible. Anyhow, I have no idea of the scale in your photo. If it's a fruit bract, though, would that make it a Rhus?
The length and shape of the involucre indicates a hybrid between Filbert Corylus maxima and Hazel C. avellana.
