Zamia madida is so named (Latin for ‘‘drenched”’) in 
allusion to the extraordinarily humid forest habitat which 
it prefers. The forests of the Golfo de Uraba area of 
northwestern Colombia have one of the heaviest rain- 
falls in all tropical America, receiving between five and 
six yards of rain a year. The plant is not uncommon in 
the region of Mutata, but it does not occur in colonies, as 
do many other species of Zamia. It is a majestic plant, 
sometimes as tall as a man, and grows erect, not spraw!l- 
ing, with the heavy ends of the leaves, on which the 
large leaflets are borne, slightly flexuous. 
Zamia madida is well characterized by the very con- 
spicuous swelling at the base of the leaflets. This swell- 
ing forms a strong collar which almost completely sur- 
rounds the apical part of the petiolule.
