Wettinia Explained

Wettinia is a genus of flowering plants in the palm family Arecaceae. The genus, established in 1837, contains some 20 species, but more seem to await discovery considering that 4 species - W. aequatorialis, W. lanata, W. minima and W. panamensis - were described as late as 1995. The genus is broadly divided into two groups. One group has the fruits tightly packed, while the other, formerly classified as genus Catoblastus, has fruits scattered along the inflorescence branches. It is not known whether these groups are both monophyletic. The genus is named after Frederick Augustus II of Saxony, of the House of Wettin.[1]

Morphology

Palms of the genus Wettinia are monoecious, medium-sized to large, and typically solitary-trunked. They have a low, dense cone of brown or black stilt roots, and pinnate leaves. The rope-like inflorescences of the plant emerge from leathery spathes, and grow in a circular pattern around one or more trunk rings beneath the crown shaft. They are unisexual, fleshy, and cream colored or white. The fruit is small to medium-sized and elongated, green to bluish black in color. It grows either dispersed along the branches or in a tightly packed ellipsoid or sausage-like cylinder.

Distribution

Members of this genus are found in Panama and in northern and northwestern South America (Venezuela, Colombia, Ecuador, Peru, Bolivia, northwestern Brazil).[2] Although none of the species are frost-tolerant, they are found primarily in cooler and higher-altitude locations, up to 2,200 m in the case of Wettinia kalbreyeri, and are particularly prevalent along the foothills of the Andes.
