分種相中，初問。次答，前示生相。七種者，青黃赤白黑紫縹（青黃之色）。所下，次明生種。離地得生，如柳榴類，其枝可栽者。從緣，即水土也。指律五種，即根枝節子雜種也。

In distinguishing the marks of seeds, the first is a question. Next is the answer, which first indicates the marks of living things. The seven types are green, yellow, red, white, black, purple, and pale blue-green (the color of bluish-yellow). From "That which..." onward, it next explains living seeds. Those that can grow when separated from the earth are like willows and pomegranates, whose branches can be planted. "From conditions" means water and soil. Pointing to the vinaya's five types, these are roots, branches, joints, seeds, and miscellaneous seeds.
