Distribution and habitat.
Plants were known only from central Ecuador, prov. Los
Rios
, Guayas, Esmeralda, and Pichincha, epiphyte on
Theobroma
or similar trees, in shaded warm forests from 200-1500 m. This is the first report for Peru.
Notes.
The closest species we could compare to is
P. topoensis
Yunck., also from Ecuador, which is similar in its epiphytic, pendent, or assurgent habit with small, succulent, alternate ovate leaves, cordulate at the base and 7-plinerved, compared to the obtuse, subtruncate based and noticeable 3-nerved leaves of
P. cacaophila
.
Peperomia nitida
Dahlst. from Brazil,
Sao
Paulo (Campinas), a widely cultivated species, is similar but with larger, light green cordulate-based leaves, only stems slightly reddish.
Peperomia portobellensis
Beurl. from Panama is also similar in shape but with slightly larger leaves. No material other than the types of these species was available for further comparison.
This species belongs to
Peperomia subg. Micropiper
(Miq.) Miq. (
Frenzke et al. 2015
).
