the head. In vagus a root of similar internal origin passes 
into the R. lateralis innervating the lateral sense organs of the 
body. Another component of the facialis is the fasciculus com- 
munis of Osborn, which was believed to represent the lobus vagi 
of fishes. This passes off into the palatinus and mandibularis 
internus, innervating the mucous epithelium of the oral cavity ; 
while in the glosso-pharyngus and vagus similar components 
‘derived from this fasciculus innervate iu like manner portions of 
the alimentary canal and its appendages. The relation of the 
results to segmentation of head was discussed. 
THE NORTH AMERICAN ‘SPECIES OF THE GENUS 
LESPEDEZA. 
BY N. L. BRITTON. 
About ten years ago I was lead to observe the species of Les- 
pedeza growing in the vicinity of New York by failing to iden- 
tify certain forms from the descriptions at my command in the 
botanical text books. Dr. Watson’s ‘“‘ Bibliographical Index ”’ 
had then recently been published, and the hints there given 
gave me a great deal of light on the question, but still the 
species and varieties there accepted were not wholly satisfac- 
tory, and as I thought I detected some errors I determined to 
accumulate specimens, in order to endeavor to determine by 
long series of the various forms and a study of their geographi- 
eal distribution, which of them were entitled to specific rank 
and which were mere conditions of development. Nearly all 
the forms that I have been able to recognize in the great num- 
ber of specimens now contained in the Columbia College Her- 
barium, and the other herbaria which I have consulted * have 
been named by one author or another, as species or varieties. 
I have endeavored to ascertain by an inspection of the types 
employed by these authors for their descriptions, which names
