👉 Pseudotetrastemma is a type of plant in the family Asteraceae, found primarily in Australia and New Zealand. It contains a single flower head with four petals, which are arranged in a symmetrical pattern around the base of each petal. This unique structure allows for the development of various forms such as pseudotetrapetalous, pseudopetalous, or pseudotetrastemata, depending on the number and arrangement of petals.
