A. corallina was previously known as A. mendesii and are often confused with A. dewinteri, which is much smaller. Their rich dark red flowers bloom in March and April. Leaves are longer, thinner and a more lighter green than A. dewinteri. Head to the mountainous regions of the middle Kunene where the river passes through the Baines Mountains in north-west Namibia to observe this plant. The sparse and difficult distribution range makes it well-protected. The high precipices they grow on are almost inaccessible, so they are not an endangered plant.
