the three collections which are at present available. 
Cotomsia: Intendencia del Meta, Cordillera La Macarena (extremo 
nordeste), Macizo Renjifo, cumbre y alrededores. Alt. 1800-1900 m. 
‘En colonias. Sobre capa de hojas secas. Espddice purptreo.’’ Jan- 
uary 6-20, 1951, Jess M. Idrobo & Richard Evans Schultes 1162 (Tyre 
in Herb. Gray).—Same locality and date. ‘“Terrestrial. Spathe green, 
bent back. Leaf discolourous, very dark green above, lucid above, pale 
green and punctate beneath. Basic colour of spadix reddish brown. ’’ 
Jesus M. Idrobo & Richard Evans Schultes 957.—Intendencia del Meta, 
Sierra de La Macarena, Central Mountains, North Ridge. Alt. 1400 
m. ‘‘Dense humid forest. Terrestrial; leaves coriaceous. Spathe green, 
tinged with red; spike brown.’” December 25, 1949, W. R. Philipson 
& J. M. Idrobo 1926. 
Anthurium macarenense I. I’. Schultes & Idrobo 
sp. nov. 
Anthurio cabrerensi proxima sed principaliter lamina 
membranacea (non coriacea), apice abrupte et longe at- 
tenuata (non acuta), spatha atrosanguinea venis viridibus 
elongato-lanceolata spadici subaequali (non spatha cuprea 
ovato-lanceolata spadicis longitudinis # aequanti) differt. 
Anthurium macarenense would seem to be very closely 
allied to 4. cabrerense Engl. trom the Departamento del 
‘Tolima in Colombia, which is described and well illus- 
trated in Engler Pflanzenreich LV. 23B (Heft 21) (1905) 
208. 
The former species differs from the latter primarily in 
having a more delicate leaf-blade which is abruptly and 
attenuately tipped, and in having a spathe which differs 
in size, shape and color. 
Cotompia: Intendencia del Meta, Cordillera La Macarena (extremo 
nordeste), Macizo Renjifo, cumbre y alrededores. Alt. 1300-1900 m.
