Herniaria glabra L. en Crassula tillaea Lester-Garland op voetpaden in de duinen bij Bergen (N.-H.)

In May 1989 Herniaria glabra and Crassula tillaea were found in the dunes near Bergen on and along dry public paths. The species occur in a kind of vegetation showing little or no relationship with the vegetation-types for which they are considered characteristic in Dutch literature. Recently both species have also been found elsewhere in the Netherlands in habitats similar to those in the dunes near Bergen.
