Privet and Hermannia, are which type of plants?
Privet A privet is a flowering plant in the genus Ligustrum. The genus contains about 50 species of erect, deciduous or evergreen shrubs, sometimes forming small or medium-sized trees, native to Europe, north Africa, Asia, many introduced and naturalised in Australasia, where only one species extends as a native into Queensland. Some species have become widely naturalized or invasive where introduced. "Privet" was originally the name for the European semi-evergreen shrub "Ligustrum vulgare", and later also for the more reliably evergreen "Ligustrum ovalifolium" used extensively for privacy hedging, though now the name is applied to all members of the genus. The generic name was applied by Pliny the Elder (23–79 CE) to "L. vulgare". It is often suggested that the name "privet" is related to "private", but the OED states that there is no evidence to support this.
Ptychopetalum Ptychopetalum is a genus of two species of flowering plants in the family Olacaceae (not to be confused with the Oleaceae or olive family), native to the Amazon rainforest. The indigenous name for the genus is Muira Puama, "potency wood". The species are shrubs or small trees growing to about 14 feet in height. Its leaves are short-petioled, up to 3 inches in length and 2 inches in breadth light green on upper surface, dark brown on lower surface. The inflorescences consist of short axillary racemes of 4 to 6 flowers each. The root is strongly tough and fibrous, internally light brown with thin bark and broad wood, has a faint odor, and tastes slightly saline and acrid.
