WHITE CINQUEFOIL 



rounded or wedge-shaped at base. Terminal leaflet 

 is largest and the pairs grow smaller toward the base 

 of the midrib. Between these pairs of leaflets are several 

 small rudimentary leaflets in pairs or scattered. 



Flowers. — Small, yellow, one-fourth to one-half an 

 inch across, borne in long terminal or axillary racemes. 



Calyx. — Top-shaped, grooved, contracted at the throat, 

 which is beset with green, hooked bristles. 



Corolla. — Petals five, yellow, small, acute. 



Stamens. — Five to fifteen, filaments slender. 



Pistil. — Carpels two, included; stigma two-lobed. 



Fruit. — T>Ty, top-shaped, with many radiating hooked 

 bristles. 



Chiefly self-fertilized. 



The tapering raceme of Agrimony, rising above 

 its shapely leaves, with its nodding, urn-shaped burrs 

 closely set along the stem, is really a graceful and 

 interesting plant. 



The small flower has five yellow petals, many 

 orange- tipped stamens, and appears on a long, slender 

 spike. The blossoms at the base of the flowering stems 

 open first, and in midsummer these stems become a 

 mass of green calyxes below, yellow flowers midway, 

 and green buds toward the tip. At first sight one 

 would scarcely place the Agrimony within the Rose 

 family, yet there it properly belongs.
