Many-flowered Unicorn-Plant (Proboscidea spicata)
The Many-flowered Unicorn-Plant, described in 1968, is known from widely separated populations in Mexico as well as in Texas, USA, where it is known to have occurred at dry, sandy terraces along the Rio Grande as well as in other disturbed sandy habitats.
The species can be distinguished from other, closely related species by its spicate inflorescences with numerous small flowers.
The Many-flowered Unicorn-Plant was last recorded in 1967, it was never found again subsequently and is possibly extinct now.
