326 RyDBERG: NOTES ON ROSACEAE 
Agrimonia gryposepala Wallr. This has gone under the 
name of A. Eupatoria L. ever since Pursh’s time or perhaps even 
since Walter’s time. In general habit and in the size of the 
fruit it approaches more the European A. Eupatoria than any 
other of our North American species; but the structure of the 
fruit and the flowers are different. See the key. It was first 
distinguished by Muhlenberg, who gave it the name A. Eupa- 
toria hirsuta in his Catalogue in 1813, but, as stated before, with- 
out proper description. It was subsequently published under 
Muhlenberg’s name by Torrey in his Flora, in 1824. The first 
specific name, however, is that of Wallroth in 1842. His is also 
the first really good and extensive description. He was the first 
one to point out the peculiar sepals and characteristic arrangement 
of the bristles of the fruit, which distinguish it from any other of 
the species of the United States. It is therefore very appropriate 
that his specific name is now restored. The specimens from Cali 
fornia, Arizona, New Mexico, and Mexico are usually somewhat 
different, but no constant characters have been found on which 
to base a separation. 
Agrimonia macrocarpa (Focke) Rydb. ‘This is the only North 
American species which approaches A. gryposepala in the structure 
of the sepals and of the fruit. It differs, however, in the elongated 
hypanthium and the more copious pubescence. Focke made it 
a variety of A. parviflora, to which it has little relationship. The 
only characters in which it approaches that species are the form 
(not the number) of the leaflets and the coarse pubescence. The 
structure of the fruit and the flower and the number of the leaflets 
are not at all the same. Its range is limited to Guatemala, from 
where the following specimens have been seen: 
GUATEMALA: Coban, 1907, von Tuerckheim 1377; Dept. Huchue- 
tenango, 1896, Seler 2504. 
Agrimonia rostellata Wallr. Muhlenberg was also the first 
one to distinguish this species and gave it in his Catalogue the 
name A. Eupatoria glabra, but without a proper description. De 
Candolle mistook it for A. parviflora Ait., probably because it 
has the smallest flowers of all our North American species. It 
has also the smallest fruit, which is different from the rest in 
‘that it is more rounded at the base and less grooved. Mr. Bicknell
