Calypso bulbosa (L.) Oakes
Orchidaceae (Orchid Family)
USDA Symbol: CABU
Calypso bulbosa is chlorophyllous but also hemi-mycoheterotrophic; that is, it makes it own food, but also utilizes at least one fungus species to provide some of its carbon intake. The known fungi involved is Thanatephorus ochraceus, a saprotroph.
A single mostly pink bilateral pendant flower with an inflated, slipper-like lip petal hangs at tip of an erect, reddish flower stalk that grows above 1 basal leaf.
This short perennial rises from a small tuber and is the only species in this genus. Named for the sea nymph Calypso of Homers Odyssey, who detained the willing Odysseus on his return from Troy; like Calypso, the plant is beautiful and prefers secluded haunts.
