Blutaparon rigidum

Blutaparon rigidum is an extinct species of the family of Amaranthaceae. She was endemic to the Galapagos Islands.

Features

Blutaparon rigidum was a small shrub with a lush and dense branching. The internodes were 5-12 mm long and smooth. The 3 to 4 mm long and 1 mm wide leaves were commended shaped and mucronate. They had a broad base and completely covered the stems. The leaf axils were covered with woolly hairs. The inflorescence was oblong and consisted of terminal spikes, which reached a length of 6 to 17 mm and width of 5 to 6.5 mm. The support sheet cover page and the perianth were white. The support sheet was ovate - heart-shaped and about 2 mm long. The bracteoles ovate - lanceolate were, keeled and 2.5 to 2.7 mm long. The apex was often bent to the inflorescence axis towards. The 2,6 to 3 mm long segments of the perianth oblong- ovate and were dull. The two side and the inner segments were keeled dull. The stamens were about 2.3 mm, 0.8 mm, the dust bag and the punch about 1.7 mm long. There were two 0.3 mm long scars that were oblong- triangular.

Status

Blutaparon rigidum has been known only by two collections from the Galapagos island of San Salvador. The first edition of Art in 1891 by Georg Hermann Carl Ludwig Baur and the second time 1905/1906 by Albert Newton Stewart was collected. Since then, the plant is considered to be extinct, which was confirmed by a search operation in 2000. Possible Aussterbeursache overgrazing by goats and donkeys are suspected.
