Xyris is the botanical name of a genus of flowering plants in the Yellow-eyed-grass family. The genus counts over two hundred fifty species, with the center of distribution in the Guianas. The leaves are mostly distichous, linear, flat and thin or round with a conspicuous sheath at the base. They are arranged in a basal aggregation. The small, yellow flowers are dioecious, borne on a spherical or cylindrical spike or head. Each flower grows from the axil of a leathery bract. The fruit is a non-fleshy, dehiscent capsule. In Xyris complanata a single flower bud on the spike appears in the morning, and expands into a conspicuous flower during the afternoon hours. The APG II system, of 2003, places the genus in family Xyridaceae, into the order Poales in the clade commelinids, in the monocots. Species include: ⁕Xyris andina Malme ⁕Xyris ambigua Beyrich ex Kunth ⁕Xyris baldwiniana Schultes ⁕Xyris brevifolia Michaux ⁕Xyris caroliniana Walter ⁕Xyris complanata R.Br. ⁕Xyris difformis Chapman ⁕Xyris drummondii Malme ⁕Xyris elliottii Chapman ⁕Xyris elongata Rudge ⁕Xyris exilis Doust & B.J.Conn ⁕Xyris fimbriata Elliott ⁕Xyris flabelliformis Chapman ⁕Xyris flexifolia R.Br.
