Veronica anagallis-aquatica | |
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]
Althaea officinalis, the marsh mallow or marshmallow, is a species of flowering plant indigenous to Europe, Western Asia and North Africa, which is used in herbalism and as an ornamental plant. A confection made from the root since ancient Egyptian times evolved into today's marshmallow treat, but most modern marshmallow treats no longer contain any marsh-mallow root.
Veronica persica is a flowering plant in the family Plantaginaceae. Common names include birdeye speedwell, common field-speedwell, Persian speedwell, large field speedwell, bird's-eye, or winter speedwell. It is native to Eurasia and is widespread as an introduced species in the British Isles, North America, eastern Asia, including Japan and China, and Australia and New Zealand.
Veronica arvensis, common names: wall speedwell, corn speedwell, common speedwell, rock speedwell, field speedwell, is an annual flowering plant in the plantain family Plantaginaceae. The species is native to Europe and a common weed in gardens, pastures, waste places, and cultivated land.
Veronica agrestis, the green field-speedwell is a species of flowering plant in the Plantaginaceae (Plantain) family. It is native to Europe, western Asia and North Africa, and has been introduced to eastern North America, India and some other countries.
Veronica hederifolia, the ivy-leaved speedwell, is a flowering plant belonging to the family Plantaginaceae. It is native to Europe, western Asia and north Africa and it is present in other places as an introduced species and a common weed. Solitary blue flowers occur in leaf axils, each with a corolla up to one centimetre (0.4 in) wide. The fruit is a dehiscent capsule.
Veronica polita, the grey field-speedwell is a species of flowering plant in the Plantaginaceae (Plantain) family. It is native to Europe, south western Asia, North Africa, the Arabian Penninsula and a few nearby countries, and has been introduced to many countries worldwide particularly as a weed of cultivation.
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.
Crassula aquatica is a succulent plant known by the common names water pygmyweed, common pygmyweed and just pigmyweed. It is an annual plant of salt marshes, vernal pools, wetlands, and other fresh to brackish water bodies. It is at least partially aquatic, living in areas which are submersed much of the time. It also lives along muddy banks and in tidally-active areas of estuaries.
Oenothera suffrutescens is a species of flowering plant in the evening primrose family known as scarlet beeblossom and scarlet gaura.

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.

Petrorhagia dubia is a species of flowering plant in the family Caryophyllaceae known by the common name hairy pink. It is native to southern Europe and the Mediterranean Basin, but it is known on other continents, including Australia and North and South America, as an introduced species and sometimes a weed. It is an annual herb growing 25 to 60 centimeters tall, but known to reach 90 centimeters in height. The leaves are up to 6 centimeters long, sheathing the stem at the bases. The inflorescence bears a head-like cluster of flowers, their bases enclosed in a large, expanded mass of wide, claw-tipped bracts. The flower corollas are each further encased in a tubular calyx of sepals. The petals are bright pink to magenta or lavender in color with darker veins. Each is heart-shaped or divided into two lobes at the tip. The fruit is a capsule containing many tiny seeds.
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.
