Carajasia is described as a new genus of Rubiaceae. It is so far known only from the mountain summits of Serra dos Carajas (Para, Brazil), where it is part of a shrubby vegetation surrounded by tropical rainforest. The new genus belongs to the tribe Spermacoceae and is positioned within it to the Spermacoce clade. Carajasia is unique within the clade in having a very particular combination of characters: flowering branches with two axillary flowers per node, homostylous flowers, corollas with a… Expand
