22.407

紺蒲成就（紺蒲正云劒蒲此乃西域菓名其色紅赤腹圓三約橫文而佛頸成就彼相故云也今時俗謂頸圓有約為嬰節者是也）。

Endowed with kambu lines (紺蒲 is properly called 劒蒲 [kambu], which is the name of a fruit of the Western Regions; its color is red, its belly is round, and it has three transversal lines; because the Buddha’s neck is endowed with that mark, it is described this way. Nowadays, common people refer to a neck being round with creases as having rings of a child's throat, which is this).
