    • n trillium A genus of liliaceous plants, of the tribe Medeoleæ. It is characterized by a solitary flower, usually with the three outer segments green and herbaceous, and the three inner segments larger, colored, and withering-persistent. There are about 15 species, 14 of which are natives of North America; 2 occur in Asia from the Himalayas to Japan. They are singular and attractive plants with a short, thick, fleshy rootstock (see cut under rhizome) producing a low unbranched erect stem terminated by a whorl of three broad deep-green leaves, each with three to five nerves, and also finely netted-veined. From their center rises the sessile or pedicelled flower, either reddish, purple, white, or greenish, with a large three-celled and three- to six-angled ovary bearing three slender spreading stigmas, and becoming in fruit an ovoid reddish berry. The contrast presented by the colored petals and prominent green sepals is an unusual one in the order, but it disappears in T. Govanianum and in T. viridescens (now esteemed a variety of T. sessile), in which the perianth-segments are all colored alike. They are known by the generic name, and as three-leafed nightshade, the white species also as wakerobin, white bath, birthroot, and in the West as wood-lily. T. erectum, the purple trillium, a strong-scented species, is also known locally as Indian balm, Indian shamrock, and nose-bleed. Of the 7 species in the northeastern United States, 3 produce white and 3 dull-purple flowers; in one, T. erythrocarpum, the painted trillium, the white petals are beautifully marked with deep-red lines. Two species of North Carolina, T. pusillum and T. stylosum, bear respectively flesh-colored and rose-colored flowers. The large handsome white petals turn rose-color in T. grandiflorum of the Eastern and Central States, and in its Californian representative, T. ovatum; in other species they commonly turn greenish. T. sessile, the only species extending across the continent, is remarkable for its closely sessile flower; T. cernuum, for its nodding peduncle; and T. petiolatum, of Oregon, for its extremely short stem. See cuts under rhizome and wake-robin.

When blood-root blooms and trillium flowers
Unclasp their stars to sun and rain,
My heart strikes hands with winds and showers
And wanders in the woods again.

The trilliums scatter their flags of snow;
But the pale wood-daffodil covers her face,
Agloom with the doom of a sorrowful race.

The sorrel drops pale blots of pink;
And, like an angled star a fay
Sets on her forehead's pallid day,
The blossoms of the trillium wink.

Star trillium, in the underbrush,
In whom Spring bares her face;
Sun eglantine, that breathes the blush
Of Summer's quiet grace;

Of Autumn's tragic pace.
