I believe Ursula has hit the nail on the head. The flower is the best identifying feature.
Some notes on wording (since I live in Mexico, also a Spanish speaking country)...
English - crest (n.), crested (adj.)
Spanish - cresta, crestado/a
Latin - crista, cristatus/a
The much more common ending is the fem. one (-a) since the words for plant and form in Spanish and Latin are feminine.
