320 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 25Q4. 



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
