Erythros is the Greek word for red. The genus Erythrina is derived from this word – an allusion to the colour of the flowers, such as this Erythrina lysistemon, photographed in the Addo Elephant National Park.
I have often mentioned the Erythrina caffra that towers over our back garden. Collectively, Erythrinas are known as coral trees these days, although some also refer to them as ‘lucky bean trees’. This is a reference to the bright red seeds that split from the black pods. These can be found scattered on the ground below the trees and are often collected simply to look pretty in jars, or to be made into necklaces or bracelets.
Combine erythros with phobia to form erythrophobia and you have the word to describe an extreme fear of blushing, or a hypersensitivity to the colour red. My dictionary also gives me erythrocyte, which is a blood cell of vertebrates that transports oxygen and carbon dioxide combined with haemoglobin.
Given all this information, could we then (just for fun) describe a particularly red sunset as an ‘erythrostic’ sunset? I present two examples, both taken in the Kruger National Park, for you to look at while you decide.
