某網站說: "The seeds are 36 x 25 mm and have a large papery wing and are dispersed by wind, in spring, when the female cone disintegrates. In their natural habitat, many seeds are lost to fungal infection and to small desert animals that feed on them. The seeds remain viable for a number of years. They germinate only if fairly heavy rain is spread over a period of several days. As these conditions rarely occur, it often happens that many plants in some colonies are the same age, as they all germinated in the same good year. The seedlings, once established,depend on the fog for survival until the next rains occur."
