I continued to draw the orchids in the morning.  After lunch, I went to Huasahuasi again with Saul.

First of all, we found a big plant of Oncidium aureum which I drew the previous day. 

Oncidium bicolor used to be called cacca-cacca in Quechua, the official language of Inca, however, nowadays this Oncidium aureum is called cacca-cacca.   The travellers would chew these bulbs for easing their thirst instead of descending to the bottome of the valley for water.
