Malouetia Tamaquarina (4ubl.) A. de Candolle 
Prodr. 8 (1844) 878. 
Malouetia Tamaquarina, widespread in Amazonian 
Brazil and in the Guianas, occurs in heavy densities in 
the trapecio amazonico of Colombia. It inhabits the low 
flood-land or rebalsa accompanying Hevea brasiliensis 
(Willd. ex Juss.) Muell.-Arg. It has an extremely abun- 
dant white latex which, according to persistent reports, 
was formerly used as an adulterant of Hevea rubber. The 
Peruvian name euchara-caspi (‘‘spoon-tree’’) is used by 
the inhabitants of the trapecio; the name refers to the 
custom of making spoons and other utensils from the 
soft, white wood of the treelet. 
The ripe fruit of Malouetia Tamaquarina forms, in 
season, a major part of the diet of the pajuz/, a bird na- 
tive to the region. There is a widely accepted belief in 
the upper Amazon that the bones of the pajui/, at the 
time of abundant fruiting of the euchara-caspi, are highly 
poisonous to dogs who may obtain and eat them. The 
poisoning agent is held to be the fruit. Such a generally 
accepted belief is, indeed, worthy of phytochemical in- 
vestigation.
