The leaves are up to 8 centimeters long and 7 wide. The inflorescence is a dense spike of many flowers. Each flower has long sepals tipped with bright purple and tubular corollas in shades of pink and purple. The fruit is a light brown, fuzzy nutlet about 2 millimeters long.
Horse chestnut: Its seeds, leaves, bark, and flowers have been used medicinally for many centuries for treating joint pain, bladder and gastrointestinal problems, fever, leg cramps, and other conditions. It may be useful for treating chronic venous insufficiency. The raw plant materials are toxic unless processed. [7] Ageratina altissima: White ...
Equisetum (/ ˌ ɛ k w ɪ ˈ s iː t əm /; horsetail) is the only living genus in Equisetaceae, a family of vascular plants that reproduce by spores rather than seeds. [2]Equisetum is a "living fossil", the only living genus of the entire subclass Equisetidae, which for over 100 million years was much more diverse and dominated the understorey of late Paleozoic forests.
The leaves are unstalked, slender, 2–10 centimetres (0.8–3.9 inches) long, and up to 1 cm (0.4 in) wide, with a coarsely toothed margin. They grow in an alternate spiral up the stem, and the lower ones wither early. The flower heads are produced in dense inflorescences and are 1 cm (0.4 in) in diameter.
Equisetum hyemale strobilus, at Darłówko on the Baltic Sea coast of Poland. Equisetum hyemale is native to central and northern Eurasia, including Iceland, Greenland, Kamchatka and Japan, where it forms clonal colonies in mesic (reliably moist) habitats, often in heavy clay or sandy soils in riparian zones of rivers and streams where it can withstand occasional flooding, but also in lime ...
Symplocos tinctoria (the common sweetleaf, [3] horse-sugar, or yellowwood) is a deciduous or evergreen shrub or tree. It is recognized by pith of twigs chambered; by foliage not notably aromatic when bruised, leaves finely hairy beneath. Shrubs or trees to 17 m tall by 36 cm diameter at breast height.

However, the leaves of Equisetum probably arose by the reduction of megaphylls, as evidenced by early fossil forms such as Sphenophyllum, in which the leaves are broad with branching veins. [ 4 ] The vascular bundles trifurcate at the nodes, with the central branch becoming the vein of a microphyll, and the other two moving left and right to ...
