86 KEY AND FLORA 
1. T. dioicum L. Earty Meapow Rue. Plant 1-2 ft. high, 
smooth and pale or with a bloom. Leaves all petioled, most of them 
thrice compound in threes; leaflets thin and delicate, roundish, 3-7- 
lobed. Flowers in slender panicles, purplish or greenish ; staminate 
ones with slender, thread-like filaments, from which hang the con- 
spicuous yellowish anthers. Rocky woods and hillsides. 
2. T. polygamum Muhl. Tart Meapow Rue. Stems from fibrous 
roots, tall and coarse, nearly or quite smooth, 4-8 ft. tall. Leaves 
twice compound, those of the stem sessile, the others long-petioled ; 
leaflets oval or oblong, often cordate, smooth or downy beneath, 
quite variable in size on the same plant. Flowers small, in large 
panicles. Sepals 4 or 5, white. Filaments club-shaped. Akenes 
short-stalked. Thickets and meadows E. 
Ill. ANEMONELLA Spach. (SYNDESMON) 
Small, perennial herbs. Leaves compound, smooth, the 
basal ones long-petioled, those of the stem sessile. Flowers 
in a terminal umbel, slender-pediceled. Sepals petal-like. 
Petals none. Pistils 4-15 ; stigmas sessile, truncate.* 
1. A. thalictroides Spach. Ruz Anemone. Stem slender, 6-10 in. 
high, from a cluster of tuberous roots. Basal leaves long-petioled, 
twice compound in threes; leaflets oval, heart-shaped, 3—5-lobed. 
Stem leaves 2-3 compound in threes, whorled, the long-stalked leaf- 
lets veiny, forming an involucre of 6-9 apparently simple leaves. 
Flowers 3-6 in an umbel, }- in. wide; sepals 6-10, white. In rich 
woods.* 
IV. HEPATICA Hill 
Involucre of 3 small, simple leaves, so close to the flower as 
to look like a calyx. Leaves all basal, 3-lobed, heart-shaped, 
thick, and evergreen, purplish-red beneath. Flowers single, 
on rather slender hairy scapes. 
1. H. triloba Chaix. Rounp-Lospep Hepatica. Lobes of the 
leaves obtuse or rounded; those of the involucre obtuse; sepals 
6-12, varying from blue to white. 
2. H. acutiloba DC. SiuArp-Lopep Hepatica. Closely similar to 
the former, except for the acute lobes of the leaves and tips of the 
involucre. 
[Both species have many local names, such as Liverleaf, Liverwort, 
Noble Liverwort, Spring Beauty.]
