Ever since Guyana became a Republic on 23 February 1970, the national flag is hoisted ceremoniously each year on Mount Ayanganna on the eve of the country's Republic Anniversary by members of the Guyana Defence Force (GDF).
On most mountains there are only 1–2 species from this genus, but 5 are known from Mount Ayanganna and the neighbouring Mount Wokomung has 6 species.
