Campomanesia lundiana

Campomanesia lundiana is an extinct species of the myrtle family ( Myrtaceae ). She was endemic in the Brazilian state of Rio de Janeiro. The specific epithet honors the Danish botanist Samsøe Lund, of the type material collected in 1825. Campomanesia lundiana described in 1892 by the Danish botanist Hjalmar Kiaerskou as Britoa lundiana and provided by Joáo Rodrigues de Mattos in the genus Campomanesia 1967.

Features

Campomanesia lundiana was a tree or shrub of non-recorded height. The young branches were dark reddish- brown with yellow, erect, silky smooth about 1.5 millimeters long hair and a shimmering and slightly metallic sheen. The dense pubescence disappeared with age. The inverted lanceolate leaves were 7 to 12 inches long and 2 to 3.6 inches wide. The upper leaf surface was along the midrib slightly pubescent and otherwise hairless. The lower leaf surface was weakly pubescent hairless up. The blade tip was pointed to pointed. The leaf base was wedge-shaped and sometimes blunt. The groove loose, weakly hairy or hairless petiole was 3 to 6 millimeters long and about 1 to 1.5 millimeters thick. The midrib and lateral veins were pressed on the upper leaf surface and protruding on the underside of leaves.

Status

Campomanesia lundiana is known only from the type material, the Samsoe Lund had collected in 1825 claims to be in the vicinity of Rio de Janeiro. However, since this region is quite well researched and the species was not rediscovered until today, it is also possible that the material from Minas Gerais comes as Samsoe Lund was mainly active as a collector in the state.
