Generative characteristics

The terminal inflorescences are semi-erect to pendulous.

The hermaphroditic flowers are radial symmetry and five-fold with a double flower envelope (perianth). There are five sepals . The five petals are pink to purple in color. There are two circles with five stamens each. The Upper constant ovary has five chambers, each with an ovule .

The fruits contain one to five seeds.

Systematics and distribution

The genus Purdiaea was established by Jules Émile Planchon in 1846 in the London Journal of Botany , volume 5, p. 250, plate 9. The generic name Purdiaea honors the Scottish botanist William Purdie (1817-1857).

It had previously been placed in the Cyrillaceae family ; after phylogenetic findings about the closer relationship with the genus of cinnamon ( Clethra ), however, it was moved to the family of Scheineller plants (Clethraceae).

There are about 14 species in the genus Purdiaea , twelve of which are endemic to Cuba . Two other species are native to South America , one species is native to Central America ( Belize , Guatemala, and Panama ).

Here is the list of Cuban species according to R. Berazaín Iturralde and the two other species:

Purdiaea belizensis (ACSm. & Standl.) JLThomas (Syn .: Schizocardia belizensis A.C.Sm. & Standl. ): It occurs in Guatemala, Honduras, Belize and Panama.
