The specimens comprising the sheet of Smith’s no. 1994 in the U.S. 
National Museum show considerable variation in the leaf-contour, 
‘the basal sinus being deeper and narrower and the teeth more round 
in portions of this material than in any other seen. The identity in 
the pubescence, floral characters, etc., indicates that this is individual 
variation rather than the mixing of species. F
