| U. grandiflora | U. perfoliata | U. sessilifolia | U. puberula | U. floridana | |
|---|---|---|---|---|---|
| leaf attachment | perfoliate | perfoliate | sessile | sessile | sessile |
| tepal planar curvature | whole tepal twirls along long axis, apex may flare | tepal margins may roll outwards, apex may flare | apex may flare | apex may flare | tepal twirls distally along long axis, apex may flare |
| tepal abaxial surface | smooth | raised orange-yellow bumps | smooth | smooth | smooth |
| stem cross-section at nodes | terete | terete | angled | angled, with rough puberulence along ridges | angled |
| leaf abaxial surface | pubescent | glabrous-glaucous | glabrous-glaucous | puberulent(-glabrous) | glabrous |
U. floridana also has a leaf-like bract (very, very near the flower) that is absent in its close relatives (U. sessilifolia, U. puberula)
