Catasetum blackii is a species of Catasetum found in South America.
Plant blooms from spring to summer with fifteen 7.5 cm wide flowers.
Plant is found growing along the Sao Francisco River in SW Bahia and Northern Minas Gerais States of Brazil at elevations of 600 to 800 meters
Grow in intermediate conditions with partially bright light. Water regularly during growing season and when plants drop leaves during dormancy reduce watering. During dormancy only water about twice a month to keep pseudobulbs from shriveling. Resume watering normally when new growths occur in spring. Plants can die easily from over watering. Plants are usually grown in bark with perlite, cork, full sphagnum moss, and tree fern
