Poison oak?

I hired a man to help me cut down a big oak tree and the hillside was infested with poison oak. I pointed it out and tried to warn him not to touch it and he nodded and told me he knew all about it. I asked him what the word for it was in Spanish and he told me, "cierda." At least, that's what it sounded like.

In this online dictionary, I see an entry for, "cierna," but that just means, "vine." There must be ways to distinguish ivy from poison oak. Does anyone here know'

poison oak - hiedra (ivy) venenosa

The botanical term for "Hiedra venenosa" is "toxicodendron radicans", which is the poison ivy.

"Poison oak" is "toxicodendron diversilobum", which, according to Wikipedia, is "avena venenosa" (never seen this before).

In any case, the "poison oak" is different from the "poison ivy" (which is "hiedra venenosa"), so, being rigorous, we cannot use this last one for "poison oak" too.

The poison oak is called, as far as I know, directly by its taxonomic term (toxicodendron), or simply, "roble venenoso".
The poison ivy is called "hiedra venenosa", and the word you heard was probably "hiedra" (ivy, loosely used).
