Reophytic plants are those that live close to fast flowing waters . Reophytic Dyckias are mostly found in Rio Grade do Sul and Santa Catarina the two southernmost Brazilian States. Fast flowing rivers are normally alpine ones These plants are only now being fully known and we have a lot to tell about them.
They grow attached to bare rocks and rarely but are found on coarse graveled areas. They frequently submerged by floods nd these waters feed them and also destroys them as they carry big drag woods, giant trunks...
They present a growing behavior similar to the those Chilean Deuterocohnias. They can form huge compact clumps of twin plants.
This massive clump of Dyckia brevifolia var.subidensis is made of the very same plant as they are all equal in every sense for they result from head divisions of one only plant.
I dare to say one plant and many heads. Just like the medusae from Greek mythology.
The smaller one is a non described new species and close to it the long known Dyckia brevifolia.
