Under our present rules of botanical nomenclature Lens phaseoloides 
supplies the oldest valid specific name for this species, that supplied by 
Mimosa entada Linn. (1758) being invalidated by the rule forbidding 
duplicate binomials. The publication of Lens phaseoloides in 1754 is valid, 
the only question in regard to it being whether Linnaeus is its author, 
or Stickman. Mr. W. F. Wight has proposed to adopt not only the specific 
designation phaseoloides, but would also replace the generic name Entada 
by Lens. While strictly considered Lens may be the oldest generic desig- 
nation, still there are very serious objections to its use as I have already 
pointed out.* As to the genus Lens the species Lens phaseoloides may be 
interpreted as its type only through a peculiar combination of circumstances.
