Are you sure the LIMIT clause is ignored? From [1] "The DESCRIBE form takes *each of the resources identified in a solution*, together with any resources directly named by IRI, and assembles a single RDF graph by taking a "description" which can come from any information available including the target RDF Dataset." (emphasis mine) The relation between the LIMIT value and the size of the resulting model is a lower bound, I suppose. Damian [1] <http://www.w3.org/TR/rdf-sparql-query/#describe>
