Filipendula Rosaceae 571 



normal 5 petals." Sometimes the inner row of petals is much reduced in 

 size. This species has been reported 4 times from Clark and Jefferson Coun- 

 ties, the authors saying: "In meadows." Doubtless these authors meant 

 hayfields because meadows, in the botanical sense, do not occur there. I do 

 not believe this species occurs there but what these authors had at hand I 

 can not determine. The manuals used by them to distinguish the species 

 are definite as far as this species is concerned. More intensive collecting 

 in southern Indiana may reveal the plant in a different habitat.

 in Asia. 



6. Geum laciniatum Murr. (Geum virginianum L. in part, of Gray, 

 Man., ed. 7 and Britton and Brown, Illus. Flora, ed. 2.) Northern Rough 

 Avens. Map 1165. This species is found more or less infrequently in low 

 ground in woodland, on the borders of swamps, ponds, and lakes, and more 

 abundantly in roadside ditches and along fences.

6a. Geum laciniatum var. trichocarpum Fern. (Rhodora 37: 292-293. 

 1935.) (Geum virginianum L. in part, of Gray, Man., ed. 7, and Britton and 

 Brown, Illus. Flora, ed. 2.) Rough Avens. Map 1166. Found in the 

 habitats of the species but probably more frequent. The map shows the 

 distribution of my specimens but it may also be found in the southern 

 part of the state. It has been reported from southern Indiana by seven 

 early authors. When these authors made their reports, however, our 

 manuals did not separate Geum canadense from Geum laciniatum and its 

 variety. Since Geum canadense is a species common to the southern 

 counties, it is probable that all or most of these reports should be referred 

 to Geum canadense or Geum virginianum. 



N. S. to Minn., southw. to N. J. and Mo. and in the mts. to Ga. 



3374. FILIPENDULA [Tourn.] Hill. Meadowsweet 



1. Filipendula rubra (Hill) Robinson. Prairie Meadowsweet. Map 

 1167. This plant is an inhabitant of springy places and prairie swamps. 

 The area covered by reports for the species is from Marshall County 

 southward to the Ohio River Counties. It is frequently cultivated. 



Pa. to Mich., southw. to Ga., Ky., and Iowa. 



3376. AGRIMONIA [Tourn.] L. Agrimony 



Leaflets (exclusive of the small, intermediate ones) generally 5-9, ovate to obovate, 



rhombic-ovate or elliptic-oblong; plants usually of a dry habitat. 



Lower surface of leaflets subglabrous or sparsely hirsute; rachis of the inflorescence 



and petioles glandular-puberulent, sparsely hirsute or glabrous. 



Mature fruit strongly striate, 5-6 mm in diameter, exclusive of the ring of stiff, 



hooked bristles; bristles in many rows, the longer ones 3.5-4 mm long and 



usually broadly spreading or reflexed; petals about 4 mm long, acuminate, 



indurated and somewhat curved inward at the tips; plants stout; root not 



tuberous; lower surface of leaflets plainly glandular-dotted.. .1. A. gryposepala.
