Bulbophyllum phalaenopsis, a rare species has very wide Phalaenopsis-like leaves. The flowers are very unusual in that they are carrion scented and smell of rotting flesh. Fortunately you have to get fairly close to the flowers to catch the scent. This orchid is easy to grow and would be treated as a phalaenopsis for culture.
Low to medium as for Phalaenopsis. Bright diffused light is best. Too much light will cause an intense reddening of the foliage.
50% or higher is ideal.
Do not allow it to become completely dry between watering.
