Adriana Hoffmann Jacoby
Born 1940. Standard IPNI form: A.E.Hoffm.

As a Chilean botanist and environmentalist, Adriana Hoffmann Jacoby has authored over a dozen books on the flora of Chile and has identified and classified more than 100 new species of cacti. She was Chile's Environment Minister in 2000 and 2001. She has advocated for the sustainable management and protection of Chilean forests, leading opposition to illegal logging in her role as coordinator of Defensores del Bosque Chileno (Defenders of the Chilean Forest) since 1992.

Hoffmann was recognized by the United Nations in 1997 as one of the 25 leading environmentalists of the decade for her efforts to protect Chile's forests. In 1999 she won the National Environmental Prize in the category of Environmental Education, awarded by Comisión Nacional del Medio Ambiente (CONAMA). For her research into Chilean flora and her work in environmental education, Hoffmann received the Luis Oyarzún Award from the Austral University of Chile in 2003. She received a Fellow Award from the Cactus and Succulent Society of America in 2009.

Hoffmann has also served on the judging panel for the United Nations Environment Programme's Sasakawa Prize.

Walking Palm

Socratea exorrhiza

Socratea exorrhiza

Some facts on this palm:

Height: Up to 25 meters.

Stem diameter: Up to 16 cm.

Leaves: Greenish blue up to 1 meter long.

Fruit: Yellow, round to oval in shape; about 3 cm. in diameter.

Habitat: Rain forests in tropical Central and South America. Requires warm, sheltered climates that are very humid as well as moist soils.

Range: Brazil, Panama, Nicaragua and Hawaii.

First described: By the German botanist and explorer Carl Friedrich Philipp von Martius, who originally named it Iriartea exorrhiza.


A walking tree? I agree: it isn't a common sight, yet Socratea exorrhiza can walk. Well, sort of. This tree's roots grow from the base of the trunk high above ground, making it appear as though it is standing on stilts. New roots constantly emerge from a higher point than older ones below. Over time the tree levitates itself off the ground, while the lower, older roots rot and fall away. The new roots grow towards better light and consequently the tree's position changes horizontally as well. The process is very slow and the palm does not seem to visibly walk, but over a period of a year, it can actually move up to 1 meter from its original position. The genus Socratea contains five species of walking palms found in tropical America. It belongs to the Arecaceae or "palm trees" family which has around 2600 species.
