Discussion

Very rarely, specimens of Hypoxis hirsuta have cylindrical ovaries and/or bracts nearly equaling the pedicels. These specimens are recognized by the umbelliform inflorescence typical of H. hirsuta. The condition appears to be pathological and is associated with a lack of seed development.
