Synonymy: V. aquatica Bernh., Begr. Pflanzenart. 66 (1835), non S.F. Gray; V. salina Schür, Enum. Pl. Transsilv. 492 (1866); ?V. catenata Pennell, Rhodora 23:37 (1921) subsp. catenata; ?V. connata Raf., Med. Fl. 2:110 (1830); ?V. connata Raf. Subsp. glaberrima Pennell, Acad. Nat. Sc. Philadelphia Monog. 1:368 (1935).
Common name: Water speedwell, blue (or pink) speedwell.
Published illustration: Butcher ( 1961) A new illustrated British flora 2:fig. 1041 .
Biology: Terrestrial annuals; racemes terminal; bracts similar to the leaves, petiolate with a broad blade; pedicels long. Naturalised. (Species 7-8).
Taxonomic notes: South-eastern Australian specimens do not fit perfectly with V. anagallis-aquatica, having affinities also with V. catenata Pennell (syn. V. connata subsp. glaberrima Pennell), which is also widely spread in the Northern Hemisphere, and V. connata Raf. (see Pennell (1935) Acad. Nat. Sci. Philadelphia Monogr. 1:365) from North America. They resemble the first in their denser leaf toothing, fruiting pedicels often longer than the bracts, and erect fruiting sepals, but are allied to the second and third in their sessile lower leaves and capsules being wider than long. Vigorous but sterile hybrids between the first 2 species are common throughout Europe, but the Australian plants form capsules with abundant seed. Style length is shorter than documented for the Northern Hemisphere.
