Found in Minas Gerais, Espirito Santo, Rio de Janiero, Sao Paulo, Parana, Santa Catarina and Rio Grande do Sul States of Brazil at an altitude of 50 to 1200 meters as a small sized, warm to cool growing epiphyte with large, ovoid, strongly compressed, clustered, deeply sulcate in time pseudobulbs partially enveloped by dry scarious bracts and carrying 2 to 3 apical, large, coriaceous, oblong-lanceolate, acute above, attenuate below leaves that blooms on a erect or arching, 2 1/2' [75 cm] long, many [40 to 80] flowered, strongly branched, mottled with dull crimson, paniculate inflorescence occuring in the fall and winter.

The O crispum complex includes O praetextum, O curtum and O gravesianum, and all are now considered to be synonyms of this name but I have left them separate as they have been known as separate species for centuries.
