SOME OF THE MORE INTERESTING PLANTS IN THE CLARENS VILLAGE CONSERVANCY. No. 4

Members of the Iridaceae are a group characterized by long strap-like leaves and flower parts in 3’s or 6’s, and having only 3 stamens. The most well-known are the bearded irises found in many gardens. These are, however, not indigenous, having originally come from the northern hemisphere. 

Indigenous members of this family occurring in and around the Conservancy are genera such as Moraea, Gladiolus, Watsonia, Hesperantha, Schizostylis, Dierama, Crocosmia, Tritonia and Aristea. 

Moraea

(named after the wife of the Swedish botanist, Linnaeus).
Closest to the garden Iris, two Moraea’s occur here, viz: Moraea tripetala, dwarf and mauve and M. alticola, found in higher parts.
