Are Widdringtonia and Solandra in the same family?
Widdringtonia Widdringtonia is a genus of coniferous trees in the Cupressaceae (cypress family). The name was Austrian botanist Stephan Endlicher's way of honouring an early expert on the coniferous forests of Spain, Capt. Samuel Edward Cook or Widdrington (1787-1856). There are four species, all native to southern Africa, where they were known in the past as "cedars" (to which they are not related) but are now known as African cypresses.
Benthamiella Benthamiella is a genus of plants in the Solanaceae family, native to Patagonia in southern South America. Its species have been described as "attractive, small, cushion plants".
