綠杉林撿毬果 edible seeds of pines cone 松子

Pinus radiata female (ovulate) cone


松子（英語：pine nut、義大利語：pinoli）即松科植物的種子，又名松仁、松仁子或松子仁，可入藥、做菜，炒熟後可作小吃。 平日常食用的松子有從紅松的種子，也有來自義大利石松的種子，其形狀略有不同。

Pine nuts, also called piñón (Spanish: [piˈɲon]), pinoli (Italian: [piˈnɔːli]), or pignoli, are the edible seeds of pines (family Pinaceae, genus Pinus). According to the Food and Agriculture Organization, only 29 species provide edible nuts, while 20 are traded locally or internationally^[1] owing to their seed size being large enough to be worth harvesting; in other pines, the seeds are also edible but are too small to be of notable value as human food.^[1][2][3][4] The biggest producers of pine nuts are China, Russia, North Korea, Pakistan and Afghanistan.^[5]

As pines are gymnosperms, not angiosperms (flowering plants), pine nuts are not "true nuts"; they are not botanical fruits, the seed not being enclosed in an ovary which develops into the fruit, but simply bare seeds—"gymnosperm" meaning literally "naked seed" (from Ancient Greek: γυμνός, romanized: gymnos, lit. 'naked' and σπέρμα, sperma, 'seed'). The similarity of pine nuts to some angiosperm fruits is an example of convergent evolution.
