Colombia. An agricultural colony established by the Colombian govern- 
ment in the valley of the middle Ric Ariguani on the southern slope of the 
Sierra Nevada de Santa Marta. The region has been alternately cultivated 
and abandoned by the Indians since pre-Columbian times and most of the 
present forest, which is again being cut over, isnot virgin. The region is well 
drained and highly accidented; the hills enclosing the valley rise to over 1,000 
meters above sea level. 
Don Diego (sea level), 11°15’ N., 73°43’ W., Magdalena, Colombia. An old 
plantation on the north coast at the mouth of the Rio Don Diego. The region 
is humid and heavily forested (Carriker). 
El Guayabalt (150 meters, approximately), 8°1’ N., 72°31’ W., Norte de Santander, 
Colombia. A station 14 kilometers by rail north of Cicuta on the railroad 
line to Puerto Villamizar. I+ is located on the banks of the Quebrada de la 
Florista, a tributary of the Zulia. The conditions are intermediate between 
the arid scrubland of Cicuta and the humid forests about Puerto Villamizar. 
Collecting may have been done at 1,000 feet above sea level, but the station 
itself is at a considerably lower altitude than Ciicuta with an elevation of 215 
meters (Osgood and Jewett). 
El Orinoco, Rio Cesar* (158 meters), 10°9’ N., 73°26’ W., Magdalena, Colombia.

area with many large open pastures on both banks, Cattle from the interior 
are driven here to graze during the dry season (December through May). 
El Panorama, Rio Aurare (sea level), Zulia, Venezuela. A site on the Rfo Aurare, 
southeast of Altagracia. It is on the higher ground of the arid region adjacent 
to the swamps and manglars on the east side of Lake Maracaibo (Osgood 
and Jewett). 
El Salado* (430 meters), 10°22’ N., 73°29’W ., Magdalena, Colombia. A col- 
lecting station on the mule trail about halfway between Pueblo Bello and

site is in the center of a broad belt of forest and rastrajo which separates the 
savannas of the Rio Cesar Valley from those of Pueblo Bello. 
Encontrados (10 meters), 9°4’ N., 72°14’ W., Zulia, Venezuela. A town at the 
junction of the Rfos Zulia and Catatumbo in the humid tropical plain south-

west of the main channel of the Rio Cesar. Camp about 5 kilometers east 
of El Orinoco. Heavily forested and more frequently flooded than the El 
Orinoco area. 
Guamalito* (600 meters, approximately), 8°34’ N., 73°27’ W., Norte de Santander, 
Colombia. A station about 3 kilometers below the town of El Carmen; 
it is in the semiarid deforested valley of the Rio del Carmen on the western 
slope of the Sierra de Periji. Some dry forest exists in the ravines of the 
opposing slopes of the valley but a more humid and heavier forest occurs on 
the summits and outer slopes of the ranges forming the valley. Much of 
the collecting was done in these forests, to an altitude of 1,000 meters. 
La Gloria* (45 meters), 8°37’ N., 73°48’ W., Magdalena, Colombia. River port 
on the right bank of the Magdalena. Collecting was done at Puerto Sagoc 
about 2 kilometers lower down. This region, in the valley between the foot

middle Rio Magdalena before it joins the Cauca and spreads into the vast 
flood plain of its lower course.
