XXVIII HIDDEN TREASURE 499 
The parts of the map covered with forest are 
represented by scattered trees, among which the 
following forms are easily recognisable : — 
£ 
No. I is the Wax palm (Palma de Ramos of the 
Quitonians ; Ceroxylon andicola, H. et B.), which 
I have seen on Tunguragua up to 10,000 feet. 
Nos. 2 and 3 are Tree-ferns (Helechos) — the former 
a Cyathea, whose trunk (sometimes 40 feet high) 
is much used for uprights in houses ; the latter an 
Alsophila with a prickly trunk, very frequent in 
the forest of Canelos about the Rio Verde. No. 4 
is the Aliso [Betula acuminata, Kunth), one of the 
most abundant trees in the Ouitonian Andes ; it 
descends on the beaches of the Pastasa to near 4000 
feet, and ascends on the paramos of Tunguragua to 
12,000. But there is one tree (represented thus ■^), 
occupying on the map a considerable range of 
altitude, which I cannot make out, unless it be 
a Podocarpus, of which I saw a single tree on 
Mount Abitagua, though a species of the same 
genus is abundant at the upper limit of the forest 
in some parts of the Western Cordillera. A large 
spreading tree is figured here and there in the 
forest of Canelos which may be the Tocte — a true 
Walnut (Juglans), with an edible fruit rather larger 
than that of the European species. The remaining 
trees represented, especially those towards the 
upper limit of the forest, are mostly too much alike 
to admit of the supposition that any particular 
species was intended by them.
