Passiflora tetrandra - kohia, New Zealand passion flower

Passion flower family: Passifloraceae

Passiflora tetrandra is a perennial climber with glossy bright-green leaves. Climbing is assisted by  touch-sensitive tendrils that grow out from the stem at the base of each leaf. Flowers of this genus are distinguished by the presence of a showy whorl (the ‘corona’) of tubular thread like structures  between the petals and stamens. Passiflora is a large pan-tropical genus of about 500 species. The species name is derived from the fact that the flowers have parts in fours (tetra=four) an exception to a genus that is characterised by flowers with parts in fives.
An endemic species found in lowland forest from the North Island to the Banks Peninsula on the South Island.
