Grown by Ron Myhr
This interesting species is a relatively new introduction, as yet without a formal name -- it was found in the vicinity of Rio das Pedras, in Brazil, hence the temporary descriptive name. It is one of the small group of micro-miniature Sinningias, along with S. pusilla, S. concinna and their forms and hybrids. Note the patterned and scalloped leaves, unlike those of concinna or pusilla. Overall, S. sp. "Rio Das Pedras" is somewhat larger than the other micro-minis. There have been no reports, at this writing, of hybrids involving this species.
