Sainfoin
Sainfoin, or SAINTFOIN, ie. "holy hay" (Onobrychis sativa), is a handsome leguminous plant, with pinnate leaves, dense pyramidal racemes of pink papilionaceous flowers, marked with lines of a deeper shade, and wrinkled one-seeded pods. It is doubtfully native on the chalk downs of south-east England, and, though native to Central Europe, is often an escape from cultivation. It is much grown as fodder for milch-cows and for sheep during winter.
