Denscantia calcicola (Rubiaceae), A New Species from Limestone Outcrops in the Brazilian Caatinga
Abstract—
The first new species of Denscantia from the caatinga biome is described and illustrated. Denscantia calcicola is easily distinguished by its plicate‐nerved and scabrous leaves, axillary inflorescences with 7‐15 glomerules, calyx tube 0.85‐1.2 mm long, bifid stigma and pollen grains with only one endocingulum.
