Figure 6.
Type collection: E. P. Killip & A. C. Smith 26153, "Dept. Junin, Pichis Trail, Santa Rosa, alt. 625-900 meters; dense forest," Peru; 6, 7 Jul 1929 (holotype U S , isotype N Y ) . Known only from the type collection, which was originally referred to the genus Steno.s2)ermatium by Krause; it is clearly a Spathiphyllum.
While represented by a single collection of two plants, S. minor is distinctive and is described as new without reservation. It is low in stature, and has proportionally rather broad leaves as compared to the other species whose locules are uniovulate (S. gracilis and S. peifulinervum). S. minor shows a strong relationship to the species of the sandstone areas of Guayana, especially to S. neblinae, but differs in the uniovulate condition of its locules.
