Description and Ethnobotany
| Growth Form | Terrestrial orchid with erect growth habit. |
|---|---|
| Foliage | Bright green leaves (5 - 8 cm long) with whitish green venation. The velvety leaves are narrowly ovate to elliptic with entire leaf margin. |
| Stems | Succulent |
| Flowers | Small flowers of white petals with yellow center. They are arranged in spike inflorescences borne on long stalks (30 cm long) |
| Cultivation | This orchid is easy-to-grow. It should be planted in fertile, well-drained, but moist soil (eg., potting mix for African violets or a mixture of fine bark, coconut peat and isolite). Plants grow well in partial shade to shade (85 - 90%). It prefers moist air, so place potted plants next to other plants to increase humidity. Avoid overwatering which leads to root rot. |
| Etymology | The species epithet "discolor" means that the plant is composed of 2 different colours. |

Plant Care and Propagation
| Light Preference | Semi-Shade, Full Shade |
|---|---|
| Water Preference | Moderate Water, Occasional Misting |
| Plant Growth Rate | Moderate |
| Rootzone Tolerance | Moist Soils, Well-Drained Soils |
| Planting Remarks | Use a well drained yet moisture retentive media for this species; although they can be grown as potted plants outdoors in shaded areas (e.g. under the shade of trees) under our local conditions, this species tends to perform better under cooler conditions (less than 25'c). It can be prone to attack by snails and slugs when grown outdoors. Do not allow media to become too wet and soggy as this can cause the plants to rot. |
