The accessions which may be expected are not unlikely to efface the distinctions between several 
admitted genera, mostly founded on single plants, resembling Coreopsis or Bidens except in hay- 
ing fertile rays. The present plant, which we possess only in an early flowering state, approaches 
the incompletely-known Narvalina, Cass. (a West Indian opposite-leaved shrub) in floral 
characters, but it could hardly be joined to that genus with our present knowledge. It is to 
Leptosyne much what Agarista is to some sections of Coreopsis ; but it is distinguished by the 
short tube of the disk-corolla, marked at the summit by a beardless ring, as well as by the 
pappus ; yet, from the eibdaeous case of Coreopsis, one should not be surprised if future dis- 
coveries were to connect them
