The inflorescence of Neobolusia tysonii is lax, bearing from two to twelve spaced flowers. The stem is not quite straight, undulating slightly from flower to flower, the flowers veering half-heartedly away from it. This soft green stem of the inflorescence is faintly longitudinally ribbed, visible in the photo.
The erect floral bracts are pointed and small, green with purplish margins in picture. They become up to 1.3 cm long.
The spoon-shaped white flower lips have irregular margins, appearing stalked.
Blooming occurs in summer (Pooley, 1998; www.africanorchids.dk).
