CANELOS TO BANGS 169 
Note on the Vegetation of the Montana 
OF Canelos 
The circumstances under which I travelled pre- 
vented me paying any attention to the phaenogamous 
plants, nor did I throughout the journey see any 
large tree in flower, save two or three times a 
species of Laurel. After the first two days from 
Canelos, I was much struck by the abundance and 
variety of the ferns and mosses : every day I saw 
ferns new to me. The scarcity of tree-ferns was 
notable, since around Tarapoto, at the same alti- 
tude, I had seen such abundance and variety of them. 
Between Alapoto and Rio Verde I first came 
on a tree-fern growing gregariously ; it was a 
species of Cyathea, with a stout trunk, and I cannot 
distinguish it from a Tarapoto species. 
Among the stemless species was a handsome 
Marattia, and I was much struck by twining species 
of several genera. In an excursion since made 
(October) as far as Mount Abitagua, I have, how- 
ever, been able to gather several of these ferns. 
Among the mosses what I most remarked was 
the great abundance of Hookeriae, which was indeed 
equally notable on the Upper Bombonasa. 
The most abundant palm, as far as Mount 
Abitagua, was Iriartea ventricosa, and up to this 
point extends the Wettinia, but west of the 
Abitagua it entirely disappears. 
In descending the western side of that mountain 
I first saw the noble Wax palm, Iriartea andicita, 
which is said to exist in some abundance on the 
ridges running down south from Llanganati. Be- 
tween the Topo and Rio Verde there is a good
