Voucher specimens are deposited in the Economic Her- 
barium of Oakes Ames, the Gray Herbarium (both at Harvard 
University) or the Herbario Nacional de Colombia in Bogota— 
or in several of these institutions. 
The families are arranged in accord with the system of Engler 
& Prantl; the genera are arranged alphabetically under the 
families. 
GRAMINEAE 
Hierochloe redolens R. Brown, Prodr. (1810) 209. 
COLOMBIA: Departamento de Santander, vicinity of La Baja, alt. 2200-2600 
m. January 14-28, 1927. FE. P. Killip et A. C. Smith 18395. 
Departamento del Norte de Santander, vicinity of Mutiscua, alt. 4000 m. 
February 20-22, 1927. E. P. Killip et A. C. Smith 19678. 
According to Killip and Smith, the itamo real is a valuable 
remedy in Santander, ‘“‘much used by aged people”’ and “‘one of 
the most valuable of medicinal plants, used for many diseases.”’ 
Coumarin has been reported from the genus Hierochloe 
(Gibbs, R. D.: Chemotaxonomy of Flowering Plants 3 (1974) 
1899) and many species, including H. redolens, have a strong 
odour of coumarin. 
PALMAE 
Jessenia polycarpa Karsten in Linnaea 28 (1856) 388. 
Throughout the Colombian area of the Llanos and the Col- 
ombian basin of the Amazon, this palm has the reputation of 
yielding an oil valuable for treating pulmonary problems. The 
oil from the pericarp is an excellent edible oil, and progress is 
now being made towards the domestication of this wild palm. 
There have been studies on the bromatology of the oil, but 
investigations concerning the widely accepted belief in the 
efficacy of the oil to relieve pulmonary troubles have not yet 
been initiated. The Maku Indians of the Rio Piraparana in the 
Vaupés employ the oil as a vermifuge (Garcia-Barriga, H. 
Flora Medicinal de Colombia 1(1974) 144-146)—a medicinal 
use still to be scientifically examined.
