Pothos subgenus Allopothos contains
several species with shingling habit (notably in Sarawak P. barberianus
and P. ovatifolius). While I have sometimes (and on occasion
memorably painfully) met with species harbouring ants (sometimes semut api -
fire ants) under the leaves it does not seem to be an obligate symbiosis in
action; in part it seems that species that are obligate symbionts have the
shingle-leaves somewhat convex in relation to the climbing surface, thus
providing a 'home' for the ants whereas these Pothos are all mainly
closely pressed to the climbing surface and only ocasionally are the leaves
sifficiently convex to enable ants to inhabit beneath them.

For the record the juvenile of Rhaphidophora
korthalsii, R. tenuis and R. beccarii are shingle-plants
and R. latevaginata remains shingling throughout its entire life also
occasionally harbour ants, as, too, does R. korthalsii and R.
tenuis in the dense fibrous degraded cataphylls, prophylls and petiolar
sheathes that clothe the active shoot tips.
