The distinct five stamens; joined at the base, shoot upward and extend into five finger like anther’s. Each anther opens along the side to reveal strips of pollen along the “knuckles” of the hand. The tips of the narrow anthers eventually curl to create the claw effect.

Propagation
Scarifying the hard seed coat can assist in germination. Soak the seeds for 24-36 hours. If you notice seeds floating just give it a soft stir to help them sink. However DO NOT remove the fuzzy orange tip on the seed. Sow the seeds in a well-drained potting mix, in a relatively tall pot, about 10 cm tall. Place the seed on top of the mix and cover with approximately 6 mm of mix, adding water throughout, but not making it soggy. Most seeds should germinate between 4-10 weeks however, slow seeds can take up to 5 months. Upon sprouting, the seeds should throw off their shell within 4 days. During this time, drip some water of the seed shell once or twice a day to keep the shell soft. If after 4 days they still have their shell, gently separate the shell with your nail. In about 2 weeks you can allow them some morning sun, gradually increasing the amount of time until around 4-5 months when they should be at full sun. In hotter climates, afternoon shade may be needed to prevent burning. Once they reach about 2-5 cm tall, transplant into larger pots. Deeper pots are preferred. The soil should stay moist through the cycle. The temperature should be kept moderate. It is recommended keeping it away from prolonged frost for the first two years.
