Dyckia brevifolia in its habitat

Dyckia brevifolia on the Itajaí-açu river  rocks.
Notice the drift wood left by the last flood.
Brevifolia stays submerged for more than weeks, during floods!
Did you know of this?

Dyckia brevifolia just grows where the river cascades and exposes bare rocks.

Above you can spot drift trash (plastic pots).
This is a regrettable idea!
This bush above is singular and it is a reophytic one as the brevifolia is.
This is Raulinoa echinata, described by Raulino Reitzii, the same botanist that described Dyckia ibiramenisis
also found close by this region. Just a few kilometers away and in another river a tributary of this one you see here. Raulinoa echinata is a genus with this single one species.  Dyckia reizii was also described by this same botanic preacher, a Catholic father, Raulino Reitz.
Raulino Reitz was our famous Bromelia man.

This was my first Dyckia.
My mother who was born in 1912 used to tell me about them and the hummingbirds that
came to visit their yellow flowers while my aunt Maria washed the clothes on the rock of a creek,
a nearby one tributary named Ribeirão do Cocho.
There is one regional Dyckia brevifolia variety named Ribeirão do Cocho.
Ribeirão means creek and Cocho means tank (where we can do the laundry)
