Pachyrhizus

Vegetable

Pachyrhizus

B tier

Pachyrhizus as a market umbrella covers yam bean species grown for tubers—primarily erosus jicama plus lesser-traded relatives. Labeling at genus level appears in seed and academic contexts more than produce stickers. Shared traits: crisp starch-water tubers, toxic mature seeds, tropical vines. Treat grocery tubers as standard jicama unless a specialty species is named. Genus-level identity links Mexican, Andean, and Asian yam bean crops. Culinary rules match: peel, raw crunch, brief cook only.
