Walte palm

The Essence

"Wettinia maynensis is a solitary, crownshafted palm of the eastern Andean foothills, ranging from southern Colombia through Ecuador into Peru. It stands on the low basal cone of stilt roots that gives the genus its collective name, the stilt palms, and carries a smooth, light-grey stem of 6-15 m topped by a tall green crownshaft and only a few large, dark green pinnate leaves. An unusual clustering-stemmed population is known from southern Ecuador, in Zamora-Chinchipe. Its most distinctive feature is reproductive: three to nine inflorescences emerge together at a single node, usually one large central pistillate inflorescence flanked by several smaller staminate ones. A phenology study that followed 101 adult palms for 2.3 years in the Colonso Chalupas Biological Reserve, in the Ecuadorian Piedmont, found flowering throughout the year, infructescences highly synchronised (80%) for almost six months, up to seven infructescences per palm, and five to eight months between fruit formation and dehiscence; compared with other Wettinia species it had the lowest male-to-female inflorescence ratio and the highest infructescence production, but fewer fruits per year. The fruits are minutely warty and hairy and hang in four to eight sausage-like clusters; monkeys and peccaries eat them when ripe, which makes the palm a hunting-attractant plant. The IUCN assessed the species as Least Concern in 2022, recording a stable population, presence in at least one protected area, and local-only use and trade. Palmpedia and Trebrown both describe it as common in the wild but not known in cultivation."

Wettinia maynensis is among the most intensively documented useful palms of the Ecuadorian and northern Peruvian Amazon, appearing in more than twenty ethnobotanical studies compiled in Palmweb's use records. Those records document palm heart eaten by Shuar, Huaorani, Quichua, Secoya, Cofán and Aguaruna people, and the fruit eaten by Shuar, Huaorani and Quichua; stems worked into house posts, floors and split-trunk boards, and into blowguns and spears; leaves used for thatch; stems burned as firewood; and seeds used for personal adornment and handicraft. The Canelos-Quichua use the roots as a kitchen tool to grate manioc and plantain, and felled trunks are deliberately left to breed edible palm-weevil larvae, probably Rhynchophorus palmarum, which are eaten and also used as fish bait. Balslev et al. (1997) record a Quichua medicinal use of the palm heart, known as quili yuyu, against intestinal infections caused by parasites; POWO likewise lists a medicine among this species' uses, alongside animal food, environmental uses, fuel and food. In Byg and Balslev's survey of the Nangaritza valley, this single species drew 64 thatch, 57 house-post, 43 firewood and 17 spear reports.
