Other info. - This species is common throughout most of Missouri, apparently except for the northwest corner of the state. It ranges throughout most of the Midwest. A. rostellata is very similar to another species, A. pubescens Wallr., but the latter is more pubescent and lacks glands on the abaxial surface of the leaves. All of the agrimonies bear fruits which will accompany the woodland hiker hither and yon, velcroed to her apparel.
