Agrimonia parvtflora Ait ? var. macToearpa Focke.^ 



Differt a planta typica fructibus majoribus, foliolis paucioribus 

 et brevioribus.^ — ^The determination is provisional. In many 

 cases it is very difficult to trace the limits between the closely 

 allied species of Agrimonia. The Guatcmala specimen agrees 

 in essential points with the A. parviflora of the United States. 

 Its fruits are much larger, but show the same shape and the 

 same direction of spines. Thc leaflcts are lcss numerous and 

 nearly as narrow, but shorter. These differences are not very 

 important, and therefore I prefer at prcscnt to consider the 

 plant as a variety. A more complcte acquaintance, however, 

 will perhaps disclose distinctive marks of greater importance. 

 (Focke). — Coban, Dept. Alta Verapaz, alt. 4,300 feet, Feb., 

 1889, v. Tiirckheim. (Ex Pl. cit. 1409.)
