Montia fontana L. in Nederland

Seeds of all specimens of Montiafontana L. from several herbaria in the Netherlands were studied scanning electron microscopically. Four main seed types could be recognised (fig. 1,2), corresponding with the types often used for dividing the M. fontana complex in species, subspecies or varieties. These main types are connected by intermediates and together they form a series of gradual variation. No other characters could be found that show a correlation with the seed types. Hence the authors refrain from a formal infraspecific subdivision of M. fontana.
