Gypsophila

Gypsophila L.

Gypsophila is a genus of ca. 150 species, mainly distributed in Eurasia (by far most diverse in Asia). One species, Gypsophila muralis L., is a very rare native in Belgium (Lambinon & Verloove 2012). In recent times it probably more often occurs as an alien, for instance as a pavement weed in cities (see also Clement 2000, van der Meijden 2005). Several species of Gypsophila are cultivated as ornamentals (mainly as cut flowers or for rock gardens). Walters (1989) and Jäger & al. (2008) provide an up-to-date overview for Europe.

Gypsophila is here still accepted in its traditional sense. While the majority of the Gypsophila species form a clade, Gypsophila in its entirety appears to be non-monophyletic. Recent molecular data demonstrated that Vaccaria, a small genus of one to four species that was thought to be closely related to Saponaria (Bittrich 1993), was found nested within Gypsophila, and a small clade of Saponaria is sister to the Gypsophila/Vaccaria clade (Greenberg & Donoghue 2011).


1       Perennial with +/- woody stock and non-flowering shoots === 2

         Annual, without non-flowering shoots === 4

2       Stem prostrate to decumbent === Gypsophila repens

         Stem erect === 3

3       Leaf base clasping. Calyx and pedicels glandular pubescent. Petals usually pinkish, 4-6 mm long === G. scorzonerifolia

         Leaf base not clasping. Calyx and pedicels glabrous. Petals usually white, 3-4 mm long === G. paniculata

4       Leaves linear, at most 2 mm wide. Petals ca. twice as long as calyx (native) === G. muralis

         Leaves lanceolate, at least 3 mm wide. Petals ca. 3-4x as long as calyx === 5

5       Plant glabrous. Leaves 3-10(-15) mm wide === G. elegans

         Plant glandular or pubescent (at least in part), never completely glabrous. Leaves usually wider === 6

6       Plant glandular hairy in the middle part of the stem. Leaves 10-25 mm wide. Calyx 4-7 mm === G. pilosa

         Plant viscid between the upper internodes. Leaves 1-15 mm wide. Calyx 3-4 mm === G. viscosa
