Does the genus Colquhounia or Prostanthera contain more species?
Prostanthera Prostanthera, commonly known as mintbush or mint bush, is a genus of flowering plants of the family Lamiaceae. There are about 90 species within the genus, all of which are endemic to Australia. The word is derived from the Greek for an appendage. Within the flowers are small spur-like appendages on the anthers.
Psychotria capensis The Bird-berry ("Psychotria capensis" ) is a southern African evergreen shrub or small tree. It belongs to a genus which is used medicinally in many regions, 'Psychotria' being from the Greek for 'rejuvenating', in reference to the healing properties of certain species. Kew lists some 2,000 species of "Psychotria" growing throughout the warmer regions of both hemispheres, but only two of them occur in southern Africa, namely "P. capensis" and "P. zombamontana".
