Stenoglottis Lindl., Companion Bot. Mag. 2: 209 (1837).
Terrestrial, lithophytic or epiphytic herb with swollen fleshy roots. Leaves several to many, in a basal rosette. Scape erect with a few scattered sheaths. Inflorescence an erect lax or dense raceme, flowers sometimes sub-secund; bracts small, shorter than ovary. Flowers numerous, white, pink or lilac, usually with darker spots. Sepals briefly united to base of column and lip, otherwise free. Petals erect, oblique. Lip spurred or unspurred, longer than tepals, 3–5-lobed.Column very short and broad; anther-loculi parallel, canals absent; pollinia 2, with short caudicles and round viscidia; staminodes present, longer or shorter than the anther; stigmas club-shaped, erect; rostellum very short. Capsules erect, ellipsoid or cylindrical.

All species have a similar life cycle and can be treated in much the same way in cultivation. They do well at intermediate temperatures and moderate, shade, with good air movement; if ventilation is poor, they develop black blotching on the leaves, or the leaves may die back completely. Plants should be potted in a free-draining terrestrial mix of bark, perlag, perlite, peat, and some loam. They die back after flowering sometimes the leaves start to turn yellow before flowering is finished- and should then be kept dry and cooler until the new growth starts to show, usually after two or three months. Remove the old leaves when they have turned brown, as they may become a focus for rot.
The best time to repot is when the new growth is just starting; repotting should be done every real or at least every other real. At this time, old dead roots can be easily pulled away. Plants are easily divided, usually one or two tubers will fall away and can be potted up separately. Once the new growth is clearly visible, careful watering can be started; the rosettes soon develop in spring and summer, and then the inflorescences start to elongate.
According to Stewart (1989), the sequence of, flowering is first, Stenoglottis woodii, followed by S. fimbriata and S. zambesiaca, with S. longifolia flowering last of all in autumn and early winter. Provided plants are kept dry while resting, species of Stenoglottis are easily grown and do well as house plants, preferably on a windowsill where they do not receive direct sunlight. The individual flowers are not large, but they are numerous, and a plant remains in flower for several weeks, if not
The genus Stenoglottis was established by John Lindley in 1837, based on a plant of or S. fimbriata from Transkei in South Africa. The name is derived from the Greek words stenos (narrow) and glossa (tongue), referring to the shape of the free part of the lip. By the end of the nineteenth century, two more species had been described, but Fritz Kranzlin, revising the genus in 1901, considered that only one species should be recognized. Another species, S. woodii, was described in 1924. V. S. Summerhayes (1968) considered two or three species to belong to the genus, but Joyce Stewart (1989) recognized four species from southern and eastern tropical Africa. A fifth species has been transferred to the genus (McDonald 1995), and a sixth species from South Africa is soon to be described. The species are all rather similar.
