Questionable

Achillea multiflora Hook. - label reads 'co-type'

Geum aleppicum Jacquin var. cuneatum B. Boivin - labels read isotype & paratype, name apparently never validly published

Oxytropis campestris DC. var. chartacea (Fassett) Barneby - label reads 'type area', but probably not close enough geographically to be a topotype
