From the Atlantic forest, Rio de Janeiro.
It was growing at the foot of and on rocks, leaves all round, hairy, only clearly visible from certain angles.
A beauty, I wish it had ripe seed pods! Rolling my eyes.

I've looked at all the Begonia species on plantillustrations, the only one which looks like this beauty is Begonia albococcinea but I don't see that in the list for the area, the leaves don't look hairy either and the flower petals are a little more pointed.

Selecting the region on Flora do Brasil might make searching the species easier.

Yes, I've come about Begonia albococcinea too and found out its not to be found in the entire Brazil. 88 species Begonia for the region Janet! Blinking

I've I've looked at the ones they give Herbarium species of,
Begonia gehertii looked like a candidate but the leaf margin is not entirely closed like in mine
A google search gives many photos but now it is clear it cannot be the one..
https://www.google.be/search?q=begonia+gehrtii&rlz=1C1CHWA_n...

Begonia ibitiocensis looks similar except for the lack of hairs on leaves and flower stems, they are not red either..
https://www.google.be/search?q=begonia+ibitiocensis&rlz=1C1C...
the herbarium species looks too much damaged..

Ah how about Begonia paulensis..
http://reflora.cria.org.br/inct/exsiccatae/504147452f5354594...
Sighing! also not..

I think I have found it; Hurray! Begonia concinna..only found one bad photo on the web but the leaf margin is entire and closed, the leaf petioles look reddish and I think I can see hairs on the leaf to the utter middle right, that angle is were the hairs are clearly visible..
The plant is in the list!

It certainly does look like Begonia concinna! It's a pity there's no shots of the flowers.

I found it on Tropicos but there's no images.

http://www.tropicos.org/Name/50222658

I searched the reference it's published in, tried to translate but got the same so it must be ancient latin. Hilarious!

http://archive.org/stream/systemavegetabil42linn/systemavege...

I can understand most of the wording, e.g. "foliis peltatis oblique" means foliage is peltate and oblique.

The original book ..

http://www.biodiversitylibrary.org/item/15255#page/1/mode/1u...

54. Begonia concinna Schott. B. acaulis, foliis peltatis oblique el-

lipticis acuminatis integerrimis utrinque pilofis,
florum cf petalis exterionbus orbiculatis, fructuum
alis bitns fubparallelis rotundatis , tertia maxima
obtura.
