Pseudohydrosme buettneri

Pseudohydrosme buettneri, commonly known as Büttner's false hydrosme, is a species of flowering plant in the family Araceae. It was described by Adolf Engler in 1892.

Description
Pseudohydrosme buettneri on average reaches about 2.5 cm (0.98 inches) long, and 2.5 cm (0.98 inches) wide, with fleshy roots, and semi-long flowers. Peduncle reaches 3 cm (1.18 inches) long, and spathe reaches around 80 cm (31.49 inches) long. Flowers are around 2 mm (0.07 inches) and 2 mm (0.07 inches) wide with the coloration unknown. It generally flowers in September.

Distribution and habitat
Pseudohydrosme buettneri is endemic to the Sibange-Farm, Libreville, Gabon, where the only specimen known of the species perished over a century ago. Its habitat is made up of lowland-evergreen forests dominated by ''Aucoumea klaineana. ''

Conservation and classification
Pseudohydrosme buettneri is listed as “Critically Endangered” by most sources, although the IUCN Red List hasn't officially assigned a conservation status to the most likely extinct species yet, for there are no known individuals left in its native range. Locals believe the species is still alive, but no solid evidence of its survival has been uncovered since its discovery.

Pseudohydrosme buettneri’s common name should be “Büttner's false hydrosme”, but was misspelled in the Latin name as "buettneri" (''Buettner's). ''
