arenicolaDescrição
comparison between Xyris iridifolia (left) and Xyris difformis (right).
first photos show the difference between the shape of the spikes, and the broad flattened scape of iridifolia versus the narrowly winged scape of difformis, highlighted by the sunlight in pic 2.
3rd photo compares habit — iridifolia taller, with longer and much broader leaves; difformis shorter, with narrower leaves.
4th pic shows seed difference — elongate and dark grey in iridifolia, rounded and pale yellow in difformis.
both found together in bottomland forest, as typical; creek in background
