- Description
- Corynocarpus rupestris subsp. arborescens is a tall shrub or small tree growing to 12 m. The leaves are glossy, leathery, and 9 to 14 cm long by 4 to 6 cm wide, with entire margins, but can be spiny in the juveniles. The base is decurrent, there are 8 to 11 pairs of lateral veins. The inflorescence is 4 to 5 cm long, the flowers are on pedicels that are 3 to 5 mm long. The sepals are ovate, 3 to 4 mm long. The petals are oblong-spathulate, minutely fimbriate at the apex, 3 to 3.5 mm long and are white in colour. The staminodes are oblong, denticulate at the apex, 2 to 2.5 mm long by about 1 mm wide (Guymer, 1984). The fruit is red and is 1 cm in diameter with a point at one end (Harden, 2008).
Corynocarpus rupestris subsp. arborescens differs from Corynocarpus rupestris subsp. rupestris by the shorter inflorescence 4 to 5 cm long (versus 10 to 21 cm long), longer sepals, (3 to 4 mm long (versus 2 to 2.2 mm long), and the longer petals 3 to 3.5 mm long (versus 2.4 to 2.8 mm long) (Guymer, 1984). - Map
