CULT.: Hort. Kew., 31 Jul 1878, labeled "Anthurium Dechardi Andre." 



Vernacular names: Colombia (Vaupes) : "pee-ka-sa-la-ree" (Gwanano) ; 

 " a-na-too-roo, " "to-mee-ka-ma-re" (Kubeo) ; "pee-a-ro," "ka-po" (Tukano). 

 Trinidad: "Arum Lily." Venezuela: "picaton" (Delta Amacuro) ; "saca frio" 

 (Merida); "vainilla" (Monagas, Sucre). 



This is a very distinct species, widely separated geographically from closely 

 related species by the Andes and the Pacific Ocean. The original material sent 

 to Kew in 1789 apparently w 7 as not a "native of the \Vest-India Islands," as 

 stated YnJBurtis's Botanical Magazine (pi. 603. 1803). Not a single collection 

 from any West Indian island is known, except from Trinidad, which is floristically 

 related to continental South America rather than to the Antilles. It would 

 therefore seem that the British colonials passed the plant from Trinidad to 

 St. Vincent before it was sent to England. 



In this genus 8. cannae folium is the most widely distributed species, but 

 it varies remarkably little except in size, despite its wide range. In Trinidad 

 the species reaches its maximum stature, and the leaves are proportionally 

 broader (about twice to two and one-half times as long as wide). The specimens 

 found near the Rio Orinoco from Puerto Ayacucho to Cerro Duida are small ; the 

 smallest specimens seen were collected on the slopes of the sandstone tabletop 

 mountains of Venezuela (in which the leaf -ratio varies to four times as long as 

 wide ) i 



This species differs from S. commutation by its narrower leaves which are 

 typically oblanceolate and widest above the middle. The spathe is commonly 

 wider in this species than in S. laeve.
