Seed Storage
Storage behavior of this species is orthodox (desiccation tolerant seeds); dry to 15-20% eRH and store at -20 °C.
Germination requirements
The seeds of this species have non-deep dormancy. Sterilize seeds before placing them on wet germination paper. Place seeds 14 days in 4ºC for breaking dormancy. Then germinate under alternating temperature regime of 15/20 ºC (the higher temperature for 16 hours in light and the lower one for eight hours in dark).
Morphology
Fruit type: Achene
Fruit shape: Elongated obpyramidal, apex truncate with short crenate corona, gradually narrowed toward base, truncate, surface longitudinally furrowed, glabrous, surface slightly lustrous, pale brownish yellow.
