Overview
Caespitose to creeping or trailing epiphytes, lithophytes, or rarely terrestrials. Pseudobulbs ovoid to cylindric, often angled, usually glossy, subtended by clasping papery bracts. Inflorescences erect or pendent racemes, produced with the emerging new growth or from mature pseudobulbs, the floral bracts often conspicuous and enveloping the ovary. Flowers cupped or spreading, produced simultaneously or in succession, usually fragrant, white, yellow, or pale brown. Sepals and petals free, spreading, the petals usually narrower than the sepals, the dorsal sepal often concave and arching over the column. Lip three-lobed, usually +/- tubular, the callus of toothed or variously textured keels often associated with warty outgrowths on the midlobe. Column straight or arching, without foot, with conspicuous wings usually continuous with a large hooded clinandrium; pollinia 4, in two pairs, naked.
Etymology
From the Greek koilos, meaning hollow, and gyne, meaning pistil or woman, referring to the deeply excavated stigma.
Distribution
A genus of about 100 species throughout the Asian tropics.
Care and Culture Card
See basic growing conditions and care information below.
Grow plants of Coelogyne in a medium-grade epiphyte mixture in azalea pots or baskets. Most species of Coelogyne will thrive given intermediate temperatures with the exception of Himalayan species which require cool-intermediate to cool temperatures. Provide bright light levels and regular watering throughout the year. Most species bloom best when pot-bound and care should be taken to avoid excessive root disturbance when repotting. Often flowering is delayed a season or two following division and repotting that disrupts the integrity of the root mass.
