Begonia eiromischa

Begonia eiromischa (English common name: Woolly - stalked Begonia ) is a most likely extinct species of the genus Begonia ( Begonia ). The first description by the English botanist Henry Nicholas Ridley was published in 1917.

Features

Begonia eiromischa had a brief and vigorous rhizome. The fleshy, pointed leaves were wrong sign and kidney-shaped. The smooth surfaces of leaves were deep green. The length and width of the leaf blade was 7.6 to 8.9 centimeters. There were seven veins. The thick, woody, densely covered with a red fluff layer petioles were 5.1 to 7.6 inches long. The smooth, red inflorescence axis was approximately 12.7 inches long. The approximately 1.27 inches wide, rose-colored flowers were arranged in two branches. The two sepals were circular. The linear petals were very narrow. The three-part style two-piece formed branches. The 1.5 -inch-long fruits had very short and rather thin rear wing.

Occurrence and habitat

Begonia eiromischa was endemic to Pulau Betong near the island of Penang, which is part of Peninsular Malaysia. She grew up on granite rock at a height of 170 m in the neighborhood of dipterocarp forests.

Extinction

Begonia eiromischa is known only from two collections made from the years 1886 and 1898. The habitat of this species is completely destroyed by agricultural change. Despite intensive searches in the 1980s, this species could not be detected. In 2007, she was therefore declared by the IUCN for " extinct ".
