are those suffruticose plants which we have met with at the 
greatest elevation on the volcano of Purasé, near wi. ona 
and on that of Antisana. 
* At the height of 4100 kidi (2103 toises;) the alpine 
plants give place to the Grasses, of which the region extends 
to 4600 métres, (2360 toises.) The Jaravas, the Stipas, a 
multitude of new species of Panicum, Agrostis, and Dactylis 
cover the soil; and present, at a distance, a golden carpet, 
which the inhabitants call pajonal. The. snow falls occa- 
sionally in this region of Grasses. 
* At 4600 métres, (2360 toises,) there are no bue 
gamous plants under the Equator. From this line to that 
of perpetual snow, the Lichens alone cover the rocks. 
Some even appear to conceal themselves under the eternal 
ice; for at 5554 métres. (8850 toises) of elevation towards 
the summit of Chimborazo, I have found upon a projecting 
rock Umbilicaria pustulata, and Verrucaria geographica : 
these are the last organized forms that we have observed 
attached to the soil at these great heights." 
From this interesting statement, it will be seen that our 
Guzmannii is reckoned amongst the most 
elevated of the phzenogamous plants; and, indeed, in the 
. Nova Genera, it is stated to have been gathered by Guzman 
upon the mountain Chorazon, district of Quito, at an eleva--
