The specific epithet honors the Danish botanist Samsøe Lund , who collected the type material in 1825.

features

Campomanesia lundiana was a tree or shrub of unknown height. The young twigs were dark reddish-brown with yellow, erect, silky-soft hair about 1.5 millimeters long and a shimmering and somewhat metallic sheen. The thick hair disappeared with age. The obscure lanceolate leaves were 7 to 12 inches long and 2 to 3.6 inches wide. The upper side of the leaf was lightly downy-haired along the midrib and otherwise hairless. The underside of the leaf was slightly downy to hairless. The tip of the leaf was pointed to pointed. The leaf base was wedge-shaped and sometimes blunt. The rutteless, slightly hairy or hairless petiole was 3 to 6 millimeters long and about 1 to 1.5 millimeters thick. The central rib and the side veins were indented on the upper side of the leaf and protruded on the underside of the leaf.

status

Campomanesia lundiana is only known of the type material which Samsoe Lund claims to have collected in the vicinity of Rio de Janeiro in 1825. Since this region has been researched quite well and the species has not yet been rediscovered, it is also possible that the material came from Minas Gerais, as Samsoe Lund was mainly a collector in this state.
