Sinningia curtiflora

In Brazil, I collected seed of Sinningia curtiflora seed from a meadow where the plants were growing in full sun.  There were dozens of plants, all with an abundant crop of seeds.  Like other full-sun sinningias, S. curtiflora keeps its tubers well below soil level.

One plant can have many tubers, connected either by thick roots (brown in the picture) or by underground runners or rhizomes (white in the picture).  A disconnected rhizome is seen at the lower right.
