 shaggy-pubescent below the racemes, often widely branched above : leaves numerous, 1-3 

 dm. long, stipules (excepting the lower ones) clasping, incised ; leaflets 11-19 or rarely 27, 

 the blades narrowly elliptic to oblong, varying to lanceolate or oblanceolate, 2.5-10 cm. 

 long, acute or acuminate at both ends, serrate, often coarsely so, accompanied by 4-5 small 

 pairs or fewer in each interval : racemes many-flowered, 2-7 dm. long, erect or spread- 

 ing : hypanthium ribbed : sepals oblong-ovate, acute : corolla 6-10 mm. broad : petals 

 pale yellow : fruit spreading or drooping, 2-4 mm. long, the body varying from subglobose 

 to turbinate, the bristles hooked, the outer reflexed, the inner erect and longer. 



In damp thickets and on borders of woods, New York to Missouri, middle Georgia and Missis- 

 sippi. Summer. 



3. Agrimonia pumila Muhl. Koots tuberous-thickened. Stems pubescent with 

 spreading hairs, 2-6 dm. tall, slender, prolonged into wand-like, simple or sparingly 

 branched racemes : leaves mostly on the lower part of the stem, 3-8 cm. long (the upper 

 ones much reduced and often 2-foliolate) ; stipules clasping, incised; leaflets mostly 3-5, 

 the blades oval to elliptic or the terminal one cuneate, 2.5-3 cm. long, crenate or crenate- 

 dentate, the interposed leaflets few and small: racemes much interrupted, 1-5 dm. long: 

 hypanthium campanulate : corolla 4-6 mm. broad : petals yellow : fruit turbinate or 

 turbinate-campanulate, 4 mm. long, the hooked bristles erect and ascending. 



In open woods, Pennsylvania to Kentucky, Florida and Louisiana. Summer. 



4. Agrimonia mollis (T. & G. ) Britton. Koots tuberous-thickened, elongated. 

 Stems loosely tomentose and somewhat villous, 3-38 dm. tall, sparingly branched, or some- 

 times in robust plants widely branched : leaves 10-15 cm. long or sometimes 3 dm. long, 

 rather numerous ; stipules varying from lanceolate and entire to broad and incised ; leaflets 

 5-9, usually 5, the blades firm, oblong, elliptic or oval, varying to ovate or obovate, 3-7.5 

 cm. long, coarsely crenate or serrate-crenate, cuneate at the base, at least as to the terminal 

 one, sometimes rounded : racemes interrupted, wartd-like, 1-4 dm. long : hypanthium rib- 

 bed : corolla 6-10 mm. broad : petals deep yellow : fruit turbinate, sometimes broadly so, 

 4-5 mm. long, the hooked bristles erect or ascending. [A. Eupatoria var. mollis T. & G.]. 



In woods and on hillsides. Connecticut to Michigan, Kansas and Georgia. Summer and fall. A 

 variety, A. mollis Bicknellii Kearney, is smaller and less branched, has 7-13 oblong or narrowly oblong 

 broadly serrate-dentate leaflets, the terminal one often cleft or lobed at the base, and fruit with longer 

 and more spreading bristles ; it ranges from Connecticut to North Carolina and Tennessee. 



5. Agrimonia striata Michx. Koots tuberous-thickened, elongated. Stems nearly 

 glabrous to loosely pubescent with spreading hairs, 2-15 dm. tall, simple or delicately 

 branched above : leaves 5-20 cm. long ; stipules lanceolate or broader, more or less deeply 

 incised ; leaflets 3-9, usually 5, the blades thinnish, obovate, oval or elliptic, 3-8 cm. 

 long, coarsely crenate-serrate or crenate, usually cuneately narrowed at the base, accom- 

 panied by few small interposed leaflets : racemes simple or compound, 7-15 cm. long, 

 slender : hypanthium granular, hemispheric : sepals oblong-ovate, obtuse, canescent within 

 at the apex : corolla 4-6 mm. broad : fruit 2.5-3.5 mm. long, spreading or recurved, 

 the body hemispheric, the hooked bristles erect or ascending, equalling the terminal 

 process or shorter. 



In shaded soil or on wooded hillsides, Connecticut to Missouri and Georgia. Summer and fall. 



6. Agrimonia hirsuta (Muhl. ) Bicknell. Koots fibrous. Stems more or less pubes- 

 cent with spreading hairs, 5-15 dm. tall, usually branching above, the branches ascending, 

 zigzag : leaves 5-30 cm. long ; stipules often 2-3 cm. long, coarsely incised, the margins 

 of each pair often overlapping ; leaflets 5-9, usually 7, the blades rather thin, elliptic to 

 oval, sometimes varying to obovate, 2-12 cm. long, coarsely serrate or serrate-crenate, 

 cuneate at the base or sometimes rounded, accompanied by 3 pairs of interposed leaflets or 

 sometimes fewer : racemes simple or mostly branched, 1-4 dm. long : hypanthium granu- 

 lar, turbinate : sepals ovate, acuminate : corolla 8-12 mm. broad : petals 5, bright yellow, 

 oblong or obovate : fruit 6-12 mm. long, the body strongly fluted, the hooked bristles 

 spreading. 



In thickets and open woods, New Brunswick to Minnesota and North Carolina. Summer. 



19. SANGUISORBA L. 



Perennial or rarely annual caulescent herbs. Leaves alternate, furnished with con- 

 spicuous stipules : blades unequally pinnate, petioled : leaflets with serrate blades. Flowers 

 perfect or polygamo-dioecious, in dense peduncled spikes or heads. Hypanthiura very 

 small, constricted at the throat. Sepals 4, imbricated, petal-like, deciduous. Petals wanting.
