240 NOTES OF A BOTANIST 
a species of Lucuma, producing an edible fruit ; 
that name is applied to many species of Lucuma 
and Achras, all natives of warm or hot countries. 
Another evidence of the approach to a hot climate 
was in the existence of a species of Echites, 
twining among the bushes, and in an epiphytal 
Marcgraviacea, quite similar in its long scarlet 
spikes to Norantea guianeitsis, though the bracts 
are small patellae, not elongated sacs, as in that 
species. A very odoriferous Citrosma, with large 
thin leaves, three together, is known by the name 
of Guayiisa, and is often taken in infusion, like the 
Guayusa of Canelos, which, however, is a species 
of Ilex. 
There were a good many herbs, of species not 
seen elsewhere. One Composita, with virgate 
stems 12 feet high, large alternate lobed leaves, 
and from each axil a small leafy ramulus bearing at 
its apex a corymb of white radiate flowers, was very 
ornamental. Orchideae were tolerably abundant, 
but prettier even than these were two Bromeliaceae; 
the one seemed at first sight merely a mass of long 
scarlet flowers growing out of the moss on'old trees 
and stones, for the leaf-sheaths are imbricated into 
a little bulb, and the blade is reduced to a spine ; 
the other (apparently an ^^chmea) has broadish 
soft leaves and large violet flowers looking at 
a distance more like those of an Iris or an 
Amaryllidea. 
On the 4th of August my company started for 
the forest, our destination being the Rio de Puma- 
cocha, a large stream rising in Azuay and falling 
into the Chanchan at about 4000 feet altitude, on 
the farther side of which much Red Bark has been
