Phacelia amabilis Constances

Saline Valley Phacelia (Phacelia amabilis)

The Saline Valley Phacelia was discovered in 1942 in the Saline Valley in the Inyo County of California, USA and was never found again since, it is thus declared possibly extinct.

It may, however, just have been a color variant of another species, the Notch-leaved Phacelia (Phacelia crenulata Torr. ex S.Watson).

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.

Tournefortia obtusiflora Benth.

Blunt-leaved Tree Heliotrope (Tournefortia obtusiflora)  

This small treelet is known from a single collection from the first half of the 19th century.  

The Blunt-leaved Tree Heliotrope was probably restricted to dry coastal forest, most of which has been altered due to the expansion of Guayaquil, now the largest city in Ecuador.  

The species is most likely extinct.

Cryptantha aperta (Eastw.) Payson

Grand Junction Cat’s-Eye (Cryptantha aperta)

The Grand Junction Cat’s-Eye was found only twice in 1892, both times somewhere around the city of Great Junction in Mesa County, Colorado, USA.

The original type locality is not really known, however, all presumed localities are more or less completely destroyed due to agricultural and urban development, the species was never found again and is considered most likely extinct.

Myosotis laingii Cheeseman

Waiautoa Forget-me-not (Myosotis laingii)

The Waiautoa Forget-me-not was apparently endemic to a very small area at terraces adjacent to the Clarence River near Lake Tennyson in southern Marlborough, South Island, New Zealand.

The species is known only from some few specimens that were collected between 1860 and 1912, it has never been recorded since and is thus believed to be extinct.
