Veronica anagallis-aquatica is a species of flowering plant in the family Plantaginaceae known by the common names water speedwell, [2] blue water-speedwell, [3] brook pimpernel.
An upright, short-lived perennial flower of medium height (50 cm) or sometimes tall (1 m), with spikes of many (20-40(60)) pale violet-bluish flowers (5–10 mm diam) with darker veins of the same colour, having four lobes that resemble petals. These flower spikes arise from the stem where leaves emerge. The leaves are opposite, rather elongated and pointed at the tip, clasping the stem, and serrate-toothed in the end half, except for the lowermost that are often stalked and lacking in teeth. Aside from reproducing by seeds, the plant sends out rooting branches that spread it vegetatively early in its growth, whilst its main stems curve along the ground rooting before rising upwards to flower, and in floods pieces will break off and root further downstream. [4] [5]
Important identification characteristics of V. anagallis-aquatica are: flower colour (purply-blue), bracts (usually much shorter than the flower stalk, and narrow), fruit (somewhat elongated), sepals (not spreading wide open on fruiting), fruiting stalks (base not spreading at a very wide angle) and leaves (somewhat broadish, and lowest stalked). [6]
Similar plants include -
V. catenata flowers are white or pale pink with rosy pink veins, bracts reaching the flowers, fruits broader than long, sepals spread wide open at fruiting, fruiting stalk bases forming a large angle to the stem (c. 90 deg), leaves somewhat narrow-looking and the lowest leaves unstalked. [6]
V. x lackschewitzii has almost no fruits forming, and the plant is usually noticeably large and robust with large floral spikes. [7]
It is native throughout the old world from southern Africa to Eurasia, and is introduced elsewhere. [8] It occurs in many types of moist and wet habitat, and it is semi-aquatic, often growing in shallow water along streambanks, in ponds, and in other wetland environments.[ citation needed ]
It is listed as threatened in Indiana, and as endangered in Massachusetts, New Jersey, and Tennessee. [9]

This page provides a glossary of plant morphology. Botanists and other biologists who study plant morphology use a number of different terms to classify and identify plant organs and parts that can be observed using no more than a handheld magnifying lens. This page provides help in understanding the numerous other pages describing plants by their various taxa. The accompanying page—Plant morphology—provides an overview of the science of the external form of plants. There is also an alphabetical list: Glossary of botanical terms. In contrast, this page deals with botanical terms in a systematic manner, with some illustrations, and organized by plant anatomy and function in plant physiology.
Erodium moschatum is a species of flowering plant in the geranium family known by the common names musk stork's-bill and whitestem filaree. This is a weedy annual or biennial herb which is native to much of Eurasia and North Africa but can be found on most continents where it is an introduced species.
Veronica serpyllifolia, the thyme-leaved speedwell or thymeleaf speedwell, is a perennial flowering plant in the plantain family. The species as a whole is native mostly to Eurasia & North America, and has three variants with their individual ranges; var. serpyllifolia has particularly spread beyond its native range.
Clematis occidentalis is a species of flowering plant in the buttercup family known by the common names western blue virginsbower or purple clematis. It is native to much of southern Canada and the northern United States.
This glossary of botanical terms is a list of definitions of terms and concepts relevant to botany and plants in general. Terms of plant morphology are included here as well as at the more specific Glossary of plant morphology and Glossary of leaf morphology. For other related terms, see Glossary of phytopathology, Glossary of lichen terms, and List of Latin and Greek words commonly used in systematic names.
Suaeda calceoliformis is a species of flowering plant in the family Amaranthaceae known by several common names, including Pursh seepweed and horned seablite.
Veronica filiformis is a species of flowering plant in the family Plantaginaceae. It is known by many common names, including slender speedwell, creeping speedwell, threadstalk speedwell and Whetzel weed. It is native to eastern Europe and western Asia, and it is known in many other regions as an introduced species.
Veronica scutellata is a species of flowering plant in the plantain family known by the common names marsh speedwell, skullcap speedwell, and grassleaf speedwell. It is native to temperate Asia, Europe, northern Africa, and northern North America in a variety of wet habitats.
Lysimachia foemina is commonly known as blue pimpernel or poor man's weatherglass, and was formerly called Anagallis foemina. It is a low-growing annual herbaceous plant in the genus Lysimachia of the family Primulaceae. In a comparison of DNA sequences, L. foemina was shown to be most closely related to L. monelli. It had been thought by many to be closest to L. arvensis, and some authors had even included L. foemina as a subspecies of L. arvensis, as Anagallis arvensis subsp foemina. These three species were among several transferred from Anagallis to Lysimachia in a 2009 paper.
Orobanche hederae, the ivy broomrape, is, like other members of the genus Orobanche, a parasitic plant without chlorophyll, and thus totally dependent on its host, which is ivy. It grows to 60 cm (2 ft), with stems in shades of brown and purple, sometimes yellow. The flowers are 10–22 mm (0.4–0.9 in) long, cream in colour with reddish-purple veins.
Oenanthe aquatica, fine-leaved water-dropwort, is an aquatic flowering plant in the carrot family. It is widely distributed from the Atlantic coast of Europe to central Asia.
Veronica montana or wood speedwell is a perennial species of flowering plant from the genus Veronica. It also belongs to the family Plantaginaceae.
Veronica catenata, the pink water speedwell, is a species of flowering plant in the family Plantaginaceae. It is native to Canada, the United States, Europe, the Azores, and northern Africa. As its common name implies, it prefers growing in or near marshes, rivers, lakes and ponds.
Veronica × lackschewitzii, the hybrid water-speedwell or Lackschewitz's speedwell, is a hybrid species of flowering plant in the Plantaginaceae family occurring spontaneously throughout Europe and in parts of North America. It is named after Paul Lackschewitz.
