Trillium cernuum
Trillium cernuum is a species of flowering plant in the family Melanthiaceae. It is the most northerly occurring species of Trillium in North America, occurring as far north as Hudson Bay. Its range extends across Canada, from Saskatchewan in the west to Newfoundland in the east, and as far south as northern Virginia. It occurs on rich, moist soils in both broadleaf and coniferous woodland.
It is a perennial herbaceous plant with one or more unbranched stems tall growing from an underground rhizome. The apex of each stem has whorl of three abruptly pointed bracts long and broad, and on strong stems, also a solitary flower hanging below the leaves on a peduncle. The flower is perfect, with three slender pale green sepals long, three broad white petals long and broad, six purple stamens, and a solitary pistil; flowering is in late spring to early summer. The fruit is a six-lobed reddish berry up to in diameter, ripening in late summer.
In Ohio, T. cernuum was collected once, in Lake County in 1879. It is now thought to be extirpated from Ohio.Gallery
