530 LILIACE^. (LILY FAMIL/ ) 



closely contiguous parallel cells lateral or slightly introrse. Stigmas, or styles, 

 stigmatic down the upper side, recurved-diverging from the globose ovary, 

 long and thread-form, deciduous. Berry globose (dark purple), 3-celled, few- 

 seeded. A perennial herb, with a simple slender stem (1-3 high, clothed 

 with flocculent and deciduous wool), rising from a horizontal and tuberous 

 white rootstock (which has the taste of cucumber), bearing near the middle a 

 whorl of 5 - 9 obovate-lanceolate and pointed, sessile, lightly parallel-ribbed 

 and netted-veiny, thin leaves; also another of 3 (rarely 4 or 5) much smaller 

 ovate ones at the top, subtending a sessile umbel of small recurved flowers. 

 (Named after the sorceress Medea, for its supposed great medicinal virtues.)

Sepals 3, lanceolate, spreading, herbaceous, persistent. Petals 3, larger, 

 withering in age. Stamens 6 ; anthers linear, on short filaments, adnate, usu- 

 ally introrse; the cells opening down the margins. Stigmas sessile, awl- 

 shaped or slender, spreading or recurved above, persistent, stigmatic down the 

 inner side. Ovary 3 - 6-angled. Berry ovate, usually 6-angled or -winged, 

 3-celled (purple or red). Seeds ovate, horizontal, several in each cell. Low 

 perennial herbs, with a stout and simple stem rising from a short and prse- 

 morse tuber-like rootstock, naked, bearing at the summit a whorl of 3 ample, 

 commonly broadly ovate, more or less ribbed but netted-veined leaves, and a 

 terminal large flower; in spring. (Name from triplum, triple; all the parts 

 being in threes.) Monstrosities are not rare with the calyx and sometimes 

 petals changed to leaves, or the parts of the flower increased in number. 



* Ovary and fruit 6-angled and more or less winged. 

 - Flower sessile ; the very broad connective produced beyond the anther-cells. 



1. T. sessile, L. Leaves sessile, ovate or rhomboidal, acute, often blotched 

 or spotted ; sepals spreading ; sessile petals erect-spreading, narrowly lanceo- 

 late or oblanceolate, dark and dull purple, varying to greenish; fruit glo- 

 bose, 6" long. Moist woods, Penn. to Fla., west to Minn, and Ark. 



2. T. recurvatum, Beck. Leaves contracted at the base into a petiole, 

 ovate', oblong, or obovate ; sepals reflexed ; petals pointed, the base narrowed into 

 a claw, oblong-lanceolate to -ovate, dark purple ; fruit ovate, strongly winged 

 above, 9" long. Rich woods, Ohio and Ind. to Minn, and Ark. 



H- -i- Flower pedicelled ; connective narrow, not produced ; leaves subsessile. 

 +* Pedicel longer than the flower ; filament shorter than the anther. 



3. T. er^Ctum, L. Leaves very broadly rhombic (2J-6' wide), shortly 

 acuminate; pedicel (1-3' long) usually more or less inclined or declinate; 

 petals ovate to lanceolate (9- 18" long), brown-purple or often white or green- 

 ish or pinkish ; stamens equalling or exceeding the stout distinct spreading or 

 recurved stigmas; fruit ovate, V long, reddish. Rich woods, N. Scotia to 

 N. C., west to Minn, and Mo. Flowers ill-scented. 



4. T. grandifldrum, Salisb. Leaves less broadly rhombic-ovate (1J-4' 

 wide) ; pedicel erect or ascending ; petals oblanceolate, often broadly so (1 1 - 2J' 

 long), white turning rose-color or marked with green; stamens with stout
