Which genus of plants is endemic to Australia, Retama or Baeckea?
Retama Retama is a genus of flowering bushes in the legume family, Fabaceae. It belongs to the broom tribe, Genisteae. "Retama" broom bushes are found natively in North Africa, the Levant and some parts of southern Europe. "Retama raetam" and "Retama monosperma" have white flowers, while "Retama sphaerocarpa" has yellow flowers. It remains an open question in taxonomy whether the members of the "Retama" genus should be incorporated into the genus "Genista" (see Genisteae). The name traces itself to the Hebrew "רותם (Pronounced Rotem)"
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".
