A novelty more than anything else, and not widely grown, O. arachnoidea is notable for the extremely fimbriate calyx, which gives the appearance of a wooly spider's web (hence the "arachnoidea"). The tiny lavender flowers have a distinctly orchid-like appearance.
This plant was awarded as "Best New Introduction" at the AGGS Convention in Baltimore in 1991. Jim Roberts, who grew this specimen, reports that the plant prefers high humidity and low light, and in those conditions the leaves are covered in fine white hairs. With lower humidity (under which this plant was grown) the hairs on the leaves are less prominent.
