Abstract


Bulbostylis cangae is a new species of Cyperaceae, thus far only known for the cangas of the Serra dos Carajás (Pará State, Brazil), herein described and illustrated. We provide a detailed description, taxonomic comments, distribution data, habitat, and conservation status of the species. Bulbostylis cangae is characterized mainly by presenting a thickened base, forming a caudex covered by persistent senescent sheaths. The new species is morphologically similar to Bulbostylis medusae, but differs by presenting trichomes on the sheath apex castaneous, glumes membranaceous, cordiform achene and discoid stylopodium.
