Holothrix is a genus of 55 orchid species in the Orchidaceae family. They are all found in Africa. They are mostly tuberous species that have minute flowers and one or two often hairy, round to oval leaves that grow flat on the ground. They usually flower during spring or summer but some do flower in autumn as well. Growing orchids from seed is a fairly specialized undertaking and it requires a bit of understanding of tissue culture techniques. If you have never grown orchids from seed we recommend that before attempting this you should first contact your local Orchid Society, or purchase a book on the subject, or both!

Holothrix aspera, commonly known as Nonnatjie, is a South African endemic orchid found growing in the Northern Cape and Western Cape provinces. It is synonymously known as Bucculina aspera or Holothrix confusa.
