TRILLIUM UNDERWOODII n. sp.
Perennial by a horizontal rootstock, bright green, glabrous. Stems solitary or clustered, 1-3 dm. tall, stout ; leaves varying from ovate-lanceolate to ovate-orbicular, 8-18 cm., long, acute or short-acuminate, undulate, sometimes crisped, with a velvety lus tre, mottled with 3 shades of green, rounded or subcordate at the base, sessile; flowers sessile, musk-scented ; sepals lanceolate, 4.5 5.5 cm. long, obtuse or acute, erect or spreading, green or purplish green ; petals lanceolate, elliptic or oblanceolate, cm. long, sessile, acute or obtuse, erect, purple ; stamens 3-4 times shorter than the petals, filaments very short, anthers 1.5-2 cm. long, sub
sessile ; styles almost wanting; stigmas recurved ; berry ovoid.
In woods and fields, North Carolina to Tennessee, south to Florida and Alabama. April and May. Ascends to 95o metres in North Carolina. Trillium sessile and Trillium Undowoodii are remarkably constant in comparative size. The two species can readily be segregated on size and habit alone and of course com parative measurements of organs would serve as an excellent basis of separation. But this is not necessary since we have such good specific characters as exist in the flower, especially as re spects the stamens and styles.
