Leatherstem Erect, perennial, shrubby plant with simple or somewhat lobed leaves. Spurge family. Toxic agent is a phytotoxin (large protein molecules that may act as antigens or as proleolytic enzymes. Sheep and goats.

Abnormal Leaf-flower (Phyllanthus abnormis) Small, bushy annual or short-lived perennial herb. Toxic agent unknown. Sheep, cattle and goats, sheep and goats are more resistant than cattle.

Guajillo (Acacia berlandieri) Shrub to small tree in the legume family with few or no prickles. Sheep, goats and possibly cattle are poisoned. Leaves contain sympathomimetic amines, principally N-methyl- B-phenethy-lamine and tyramine.
