O nome científico da mandioquinha é Arracacia xanthorrhiza. It is sometimes called white carrot in English, but that name properly belongs to white varieties of the common carrot.
The leaves are similar to parsley, and vary from dark green to purple. The roots resemble fat short carrots, with lustrous off-white skin. The interior may be white, yellow, or purple.https://en.wikipedia.org/wiki/Arracacia_xanthorrhiza
