Holothrix

Two of the 46 Holothrix species are found in the Arabian peninsula while the rest are endemic to Africa. Of these 23 are found in South Africa. Plants have one or two round to egg shaped leaves pressed to the ground. The leaves are normally covered in fine hairs. The inflorescence is terminal and normally the flowering stem is also covered in hairs. The flowers are generally small. The lip is generally 3-lobed, more often with multiple lobes giving a distinct star-like look to the flowers. Flower colour ranges from greenish to white, some with striking lip markings. Plants are terrestrial or lithophytic and have a definite dormant period - normally during the dry season.
