《梦溪笔谈·药议》
又如筀竹笋，有二月份生的，有三四月份生的；还有五月份才生的，叫做晚筀。水稻也有七月份熟的，有八九月份熟的；还有十月份熟的，叫做晚稻。
始筀竹笋，有二月生者，有三四月生者，有五月方生者，谓之晚筀；稻有七月熟者，有八九月熟者，有十月熟者，谓之晚稻。
For example, tender shoots of a certain type of bamboo appear in February, March or April; and there are also those which appear in May, called late bamboo shoots. Rice crops may ripen in July, August or September; and there are also those which ripen in October, called late rice.
