Lost Sunflower (Helianthus praetermissus)  

The Lost Sunflower is an enigmatic species only known from a single specimen that was collected in 1851 in Cibola County in western New Mexico, USA.

The species was superficially quite similar to the Common Sunflower (Helianthus annuus L.), from which it differed by its rather narrow linear leaves; it was annual, reached a size of about 90 cm and had a single large flower with yellow florets.


The Lost Sunflower may be an extinct species, however, there is the possibility that it might turn out to be identical with the Pecos Sunflower (Helianthus paradoxus Heiser), itself an endangered species.
