''Chionographis'' species are perennial flowering plants that grow from [rhizome](/source/rhizome)s.  They produce a basal [rosette](/source/rosette_(botany)) of [evergreen](/source/evergreen) leaves, from the center of which emerges a flowering [scape](/source/scape_(botany)).  The scape produces a spike of many small white flowers.  The flowers are [zygomorphic](/source/zygomorphic) in shape, and when [perfect](/source/plant_sexuality) have six [tepals](/source/tepals), one [pistil](/source/pistil), and six [stamens](/source/stamens).  However, not all individuals have perfect flowers.  Many populations feature [gynodioecy](/source/gynodioecy),<ref>{{cite journal |doi=10.1086/297130 |author=Masayuki Maki and Michiko Masuda |year=1993 |journal=International Journal of Plant Sciences |title=Spatial Autocorrelation of Genotypes in a Gynodioecious Population of Chionographis japonica var.
