Size, viability and germination were studied in a sample of 2000 seeds from two individuals of the relict endemic Abies pinsapo Boiss. growing in Serrani?a de Grazalema (southern Spain). Seed mass and viability showed considerable variation both within and among trees. A large proportion of unfilled, mostly empty seeds lighter than 60 mg was found with a germination rate as low as 8 %. Seeds heavier than 60 mg germinated at much higher rate (33 %). As a whole, 26% of all seeds (N= 1280) germinated.Seeds with manually injured testas loose virtually all germination capacity (0.2 %). Seeds germinate soon after dispersal if the necessary conditions are met, while germination seems unlikely on subsequent years.
