Botanical Garden survived. It was first seen by him about 10 miles below Cuzco, along 

 the railroad running to Juliaca, and was frequently observed a long distance below Cuzco, 

 being easily recognized by its scarlet flowers, which in September were just appearing. 



In June 19 14, Kllwood C. Erdis collected living specimens 40 miles west of Cuzco, at 

 2,450 meters altitude, but these died. In November of the same year he again collected 

 the species, this time in flower. 



In May 1915, O. F. Cook and 

 G. B. Gilbert collected the plant at 

 Ollantaytambo, Peru, at an altitude 

 of about 3,000 meters. These spec- 

 imens were accompanied by both 

 flowers and fruit, and some good 

 habit and detail photographs were 

 taken. 



Figure 154 is from a photo- 

 graph taken by O. F. Cook at 



Ollantaytambo, Peru, in 1915; 

 figure 155 shows portions of the 



plant photographed.
