Seed Storage
The 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 are dormant. Sterilize seeds before placing them on wet germination paper. Place seeds for two weeks to two months at 4 ºC to germinate uniformly. Then germinate under an alternating temperatures of 20 ºC (16 hours of light) and 15 ºC (8 hours of darkness).
Morphology
Fruit type: Schizocarp (schizocarp is an indehiscent dry fruit that consists of two not compressed or compressed lateraly/dorsally carpels called mericarp)
