most plants found other then ficus are grasses, bromes and orchids. not much more then that. not many short busy plants other then ferns.
the weeds or grasses are creeping by nature and enjoy the leaf litter. moss is good too for the ground.
the phants are found in close distance to water; streams, where there are taller plants but near the bushy area where they inhabit it's mostly flat with
grasses, leafs, etc. a fern or so but nothing with big leafs. those plants happen close to the water.
there is a video that you can about madagascar and many sites have owners with many photos and personal notes on the terrain, flora and such that can help. if you want to learn more look for images Ranomafana and Andasibe as well as other areas they've been seen.
