The reproductive biology of Stellaria longipes Goldie (Caryophyllaceae) in North America

Stellaria longipes is a very variable species of circumpolar distribution and wide ecological amplitude. Individuals are herbaceous, perennial, and facultative outbreeders. Gynodioecy is very common. We studied the microsporogenesis and embryo development in both male sterile and male fertile genotypes. Male sterile plants are vigorous and set more seed than the bisexual genotypes.
