Holothrix incurva inflorescence and scape

The inflorescence of Holothrix incurva seen here is fairly lax and not cylindrical. Its lemon-yellow flowers face in one direction, an arrangement called secund. The inflorescence becomes about 4 cm long. The total flower stems grow only about 12 cm tall, annually from ovoid perennial tubers. The stem is densely covered in soft, pale hairs. The ovaries of the flowers are short.

The sepals are small, greenish and fleshy, tapering to pointed, hairy tips. The lateral petals are narrowly thread-like, although slightly wider at the base, diverging above the flower centre. The lip below the flower centre, where the broad column resides, is five-lobed, its lobes thin, linear, emerging from a shared broad base about as long as the lobes. The spur below the lip is broadly conical (iNaturalist; iSpot; www.africanorchids.dk; www.pacificbulbsociety.org).
