It is little surprise that this plant is growing in Lisbon, Portugal; it is named after Henri Cayeaux, who was the director of the Botanic Garden of Lisbon during the late 19th / early 20th century. Considering Cayeux’s work with hybridization of other plants, it is very likely he was also the plant breeder responsible for this cross, thought to be between Dombeya burgessiae and Dombeya wallichii.
The common name for this plant is pink ball dombeya or pink snowball. One of its parents, Dombeya wallichii, has the common name of tropical hydrangea (though it is not a hydrangea).
