XVIII CANELOS TO BANGS 167 
Among the species already known may be men- 
tioned the fine Hookeria pendula, discovered by 
Humboldt and Bonpland in New Granada, and the 
Hemiragis aiirea (Lam.), Brid., which adorned the 
trunks of trees with its great clusters. ... 
The most precious of the Hepaticae are often, as 
we know, very minute ; in order to find them a 
scrupulous search made without haste is necessary. 
In spite of that, he found some novelties, and among 
them an unpublished genus, the Myrio-colea h^roi^ata, 
represented on Plate xxii. of his book,^ which is 
perhaps the most interesting that he has ever found. 
It was growing on bushes watered by the stream 
of the Topo, and it is the only agreeable souvenir 
he preserves of that river. All the Hepaticae 
gathered in the valley of the Pastasa at a height 
from 5500 down to 1000 feet, that is to say, from 
the cataract of Agoyan downwards, belong to the 
forest of Canelos, and, as will be seen from his 
book, they are very numerous. 
Bafios lies just at the foot of Mount Tungu- 
ragua, and upon its wooded sides there was plenty 
to occupy the author, but he did not cease thinking 
of the beautiful ferns he had seen on the other side 
of the Topo, and as soon as paper arrived from 
Guayaquil he made preparations for again pene- 
trating into the forest. With four cargueros, his 
servant, and provisions for twelve days, he took the 
Canelos road on the 6th of October. But the rains 
had not yet abated on the eastern side of the Cor- 
dillera, and when he arrived at the Topo he found 
crossing impracticable. Two nights he waited on
