Cryptantha hooveri I. M. Johnson

Hoover’s Cryptantha (Cryptantha hooveri)

Hoover’s Cryptantha was an annual, 5 to 20 cm tall plantlet with simple or branched stems and linear leaves that inhabited grassland communities on sandy soil.


Hoover’s Cryptantha was last recorded in 1939 and may be extinct, however, the species is said to be hard to identify, so there’s some hope that it may still exist but may just have been overlooked so far.
