Gomidesia cambessedeana

Myrcia neocambessedeana ( Replaced synonym: Gomidesia cambessedeana O.Berg ) is an extinct species of the myrtle family ( Myrtaceae ). She was endemic in the Brazilian state of Rio de Janeiro.

Features

Myrcia neocambessedeana was a woody plant of non-recorded plant height. The young twigs, the leaves, the flowers and the buds were hairy rust. The against-constant and nearly seated leaves were divided into petiole and leaf blade. The petioles was 1.3 mm long. The paper-like leaf blade was at a length of 88-97 mm and a width 20.3 to 22.6 mm ovate - lanceolate with gradually tapered at the top. The little bent leaf margin was ciliated and covered with scattered, transparent stains. The upper leaf surface was bare, hairy, the lower leaf surface sparsely. The midrib was pressed on the upper leaf surface, protruding on the underside of leaves and covered with dense hair curry comb.

The flowers were placed in 50.8 mm long, racemose inflorescences. The erect, hairy flower buds were 4.5 mm long. The sepals were pointed - lanceolate. The four egg-shaped ovary were zweikämmerig. The stylus was 6.8 mm long.

The heyday was in December.

Status

Myrcia neocambessedeana has been known only from two flowering branches from the collection of the botanist Karl Beyrich from 1825. The species was discovered in a forest near Santa Anna in the Brazilian state of Rio de Janeiro. In 1998, she was taken by the IUCN Red List of extinct plant species.

System

1857 Otto Karl Berg described this species under the name Gomidesia cambessedeana in Flora Brasiliensis by Carl Friedrich Philipp von Martius. 2010, the genus Gomidesia synonymised with the genus Myrcia and renamed this taxon in Myrcia neocambessedeana.
