224 POPULAR FIELD BOTANY. 
Agrimony. ‘This is the only plant found in flower during 
this month in the eleventh class. It is very pretty, and 
common on the borders of fields, waste places, and road- 
sides. The leaves are very handsome, being large and 
deeply cut at the edge, divided even down to the main stalk, 
and the intermediate space filled up with little leaflets. 
Flowers yellow, on a long simple spike, with a little leaf at 
the base of each flower. The stamens vary much in num- 
ber. Fruit very much beset with bristles, and consequently 
clinging to anything which passes; so that by this means 
the seeds become much dispersed, 
IcOSANDRIA. POLYGYNIA. 
CALYCIFLOR. ROSACE2. 
ROSA. (Rosz.) 
Generic Character. Calyx urn-shaped, contracted at the top, 
and terminating in five segments; this, when ripe, forms the 
fruit. Petals five. 
There are nineteen species of wild Rose, most of them 
difficult to distinguish from each other; but I will mention 
the most common.
