| ALTITUDES. 
All the species of this genus belong to the high alpine flora of the Andes; in the 
northern regions they are not found below about 3,900 m. and in Chili they only occur 
above an altitude of 2,500 m. 
With regard to exact altitudes the information is somewhat meagre, but some 
definite measurements in connection with the flora have been made by Whymper, 
Conway, Fitzgerald, Fries, and others. Whymper collected plants of N. phyllanthos 
and N. Jamesonii in Ecuador, and found plants of the former species on Antisana at 
from 4,600 to 5,000 m.* ; 
Conway's plants from the high Andes of Bolivia have been published in the Journal 
of the Linnean Society f, and it is worthy of note that Nototriche flabellata was the 
highest plant found by him; it occurred at an altitude of 5,640 m. (18,500 ft.), between 
the mountains Illimani and Illampu at about 16° S. lat. i 
In Ecuador, according to Whymper f the line of permanent snow is somewhat 
variable, being as low as 14,300 ft. on some mountains, but from the data supplied it 
appears that the snow line may be considered to lie between 14,500-15,500 feet (4,420-
