than its flowers. The long stigmas of the latter give them 

 an insect-like appearance. 



PLATE XII 



WHITE TRILLIUM, Trillium grandiftorum. Root. A 

 short, scarred rootstock. Stem. Simple, stout, 8'-i8' 

 high. Leaves. Broadly ovate, three in a whorl at the 

 centre of the stem. Flower. Solitary, large, erect, white 

 or purplish-pink. Perianth. Of three green, lanceolate 

 sepals and three white, oblanceolate, erect, spreading 

 petals. Stamens (a). Six, with anthers longer than the 

 filaments. Pistil (b). With a three-angled ovary and 

 three stigmatic styles. Fruit. A round, black berry. 



The large, triangular blossoms of these trilliums 

 brighten many acres of woodland, shining like stars 

 among the Bellworts and Solomon's Seals, in May or 

 June, east of the Mississippi. A monstrous form of 

 this, with only two leaves, was found in Michigan. 



NODDING TRILLIUM, T. cernuum, is similar, with a 

 smaller, white, nodding flower. It blooms over the same 

 range a little earlier. 



PAINTED TRILLIUM, T. undulatum (or T. erythrocarpum), 

 is slightly larger and blooms over the same time and range 

 as the last. It has an erect, white flower streaked with 

 purple or red. 



EARLY TRILLIUM, T. nivale, is much smaller, with 

 petioled leaves and an erect, white flower. It appears in 

 early spring, from Pennsylvania to Minnesota and south 

 to Kentucky. 



PRAIRIE TRILLIUM, T. recurvatum, is a little larger, hav- 

 ing a sessile, erect flower, with recurved sepals and 

 frequently blotched leaves. It ranges south from Minne- 

 sota through the Middle States. 



SESSILE-FLOWERED TRILLIUM, T. sessile, has sessile 

 leaves and flowers. The leaves are often blotched, and 

 the flowers are purple or green and fragrant. It ranges 

 from Pennsylvania south and w r est to the Mississippi. 



WAKE-ROBIN, BIRTH-ROOT, T. erectum, has a purple- 

 red or pink or greenish, unpleasantly scented flower on a 

 stalk rising above the sessile leaves. It ranges east of the 

 Mississippi.
