Meristic and Organogenetic Variation in Ruppia occidentalis and R. maritima

open access: yesInternational Journal of Plant Sciences, 1993
Floral meristic and organogenetic variation was sampled in Ruppia occidentalis from an alkaline lake of the Nebraska Sandhills and in Ruppia maritima var. rostrata from a saline, non-Sandhills lake nearby. The androecium is meristically stable, always having two stamens, but the gynoecium is not. Seventy-two percent of the flowers of R.
