Typhonium jonesii is a perennial herb that propagates by underground bulbs or tubers which sprout and flower more than once. The leaf blade is deeply trilobed, with a large central lobe and two smaller lobes extending outwards from the base of the leaf. The leaf segments are linear. A pale mauve-cream spathe or bract encloses or spreads from the base of the flower spike, emerging along with new season leaves.
