The cows pictured here came to investigate the noise I made while searching for tadpoles. They stared impatiently and I sifted through samples, waiting until I left to continue their daily grazing.
A spiny Fabaceae, Mimosa pigra inhabits the margins of wetlands and is touch-sensitive. It’s flowers form a small, ball-like inflorescence and develop into seed-filled pods when fruiting. Among other characteristics, M. pigra is told from M. dormiens, another common spiny plant at wetland margins, in having curved spines along leaf rachis and more erect stems.
