Where is Serra do Cipo, Brazil?

[Margaret L. Baker]

We are currently working with number of plants collected from Serra do Cipo
in the state of Minas Gerais, Brazil. Can anyone help us locate it?

Just so no-one wastes any time, we've checked the Board of Geographic names
gazeteers, the Times atlas, Websters Geographic Dictionary, etc. but we
haven't found it listed anywhere.

Can anyone help us with longitude and latitude or even an approximate
location description like "100 miles SE of Rio".  Anything anyone can tell
us is more than we have now.

Thanks!  Marg.
