Discussion The only species in a genus confined to California, Chaparral Pea contributes to the state's unique flora. Rarely reproducing from seed, it grows new stems from roots that spread, especially after fires. It is sometimes called Montana chaparral pea even though it is endemic to California. Two varieties are recognized. Chaparral pea is important browse for black-tailed deer.
