The itinerary of the Miilford Expedition was fully described, 

 and a general account of the floral features of the regions trav- 

 eled was given in the Journal of The New York Botanical Gar- 

 den for August, 1922, pages 101-112. For the benefit of those 

 who have not this publication at hand, the following brief resume 

 is presented. 



Collections began in early July at Pongo de Quime, a settle- 

 ment just across the crest of the eastern Cordillera, at an alti- 

 tude of some 15,000 feet, about 40 or 50 miles east of Eucalyptus, 

 a station on the xVntofagasta-La Paz Railroad, and at the head 

 of the Quime River. As a matter of fact, the very first plants, 

 cactus and Caiopliora, were collected at a point more than a 

 thousand feet higher. At that season, the beginning of winter, 

 and at that altitude, the edges of the streams in the vicinity were 

 ice-bound, but these plants, cuddled under the edges of rocks, and 

 exposed to strong sunshine, managed to expand their brilliant 

 blossoms. The journey from Pongo to Canamina, having an 

 altitude of 3,500 to 4,500 feet, lay alternately along the valley 

 streams and across high ridges, and occupied about four days. 

 During this time, I was extremely ill and without any great hope 

 of surviving to reach my destination, so that collecting was im- 

 l^ossible and but little note could be taken of my surroundings. 

 Dr. White, who followed a few days later, made a small but inter- 

 esting collection along this route. From Canamina to Espia, 

 about 500 feet lower, the journey lay along the Canamina and 

 Meguilla Rivers. Both at Canamina and along this route, we 

 made rather extensive collections. At Espia, where the Meguilla
