T. laticordatum is a robust, green, rather fleshy species with broadly winged green petioles, and rather narrow and slightly recurved green exterior bracts. The broad green leaves have 3-4 broad and somewhat recurved side-lobes and a broad rounded end-lobe. It is perhaps most easily confused with T. ancistrolobum which has coloured midribs and bracts and is a darker green. Its relative T. expallidiforme is also similar but has more dentate leaves and a smaller apiculate endlobe.
