When
picked up, these
plants from limestone outcrops were half-dry due to severe dryness. This
somewhat curious morph differed from typical G. robertianum (Geraniaceae): (i) the plant
was smaller, including the leaves and the
flowers, (ii) the different parts of the plant were
only sparsely hairy, and (iii) practically no smell was observed. The anthers
were
purple and the pollen grains of the dried plant are yellow. Some features of the plant
are slightly reminiscent of the closely related Central European G. purpureum
Vill.
Another expression of the variability of G. robertianum
was a stand that solely comprised white-flowered plants
(Finland, Lohja, Virkkala, 1984).
