''Pellionia'' is a genus of flowering plants in the family Urticaceae. The flowers of Pellionia are white globules held on stalks above the plant, which respond to changes in temperature by releasing their pollen as little puffs of smoke.

Pellionia Repens
''Procris repens'' is a species of flowering plant in the nettle family, Urticaceae, commonly known as the ''watermelon begonia'' or ''sisik naga'', although the latter name may also refer various ''Pyrrosia'' species. ''P. repens'' is an interesting specimen to demonstrate the metamorphosis of chloroplasts (outward of cell) to amyloplasts (inward of cell) if studied with a microscope. Under its synonym ''Elatostema repens'' it has won the Royal Horticultural Society's Award of Garden Merit. ''E. repens'' var. ''pulchrum'' has also won the award. ''Procris repens'' is also commonly referred to as ''Pellionia repens,'' although this name is now regarded as a synonym of ''Procris repens''. Biology Description ''P. repens'' is a small herbaceous creeper that can reach 15 cm in height and 60 cm in length. Its leaves have toothed edges and are usually 2.5 to 10 cm in length and 2 to 5 cm in width. Its distinctive leaves have a pattern that resembles watermelon rinds or th ...

Urticaceae
The Urticaceae are a family, the nettle family, of flowering plants. The family name comes from the genus '' Urtica''. The Urticaceae include a number of well-known and useful plants, including nettles in the genus ''Urtica'', ramie (''Boehmeria nivea''), māmaki ('' Pipturus albidus''), and ajlai ('' Debregeasia saeneb''). The family includes about 2,625 species, grouped into 53 genera according to the database of the Royal Botanic Gardens, Kew and Christenhusz and Byng (2016). The largest genera are '' Pilea'' (500 to 715 species), '' Elatostema'' (300 species), '' Urtica'' (80 species), and '' Cecropia'' (75 species). '' Cecropia'' contains many myrmecophytes. Urticaceae species can be found worldwide, apart from the polar regions. Description Urticaceae species can be shrubs (e.g. '' Pilea''), lianas, herbs (e.g. '' Urtica'', '' Parietaria''), or, rarely, trees ('' Dendrocnide'', '' Cecropia''). Their leaves are usually entire and bear stipules. Urticating (stinging) h ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flowering Plant
Flowering plants are plants that bear flowers and fruits, and form the clade Angiospermae (), commonly called angiosperms. They include all forbs (flowering plants without a woody stem), grasses and grass-like plants, a vast majority of broad-leaved trees, shrubs and vines, and most aquatic plants. The term "angiosperm" is derived from the Greek words ἀγγεῖον / ('container, vessel') and σπέρμα / ('seed'), meaning that the seeds are enclosed within a fruit. They are by far the most diverse group of land plants with 64 orders, 416 families, approximately 13,000 known genera and 300,000 known species. Angiosperms were formerly called Magnoliophyta (). Angiosperms are distinguished from the other seed-producing plants, the gymnosperms, by having flowers, xylem consisting of vessel elements instead of tracheids, endosperm within their seeds, and fruits that completely envelop the seeds. The ancestors of flowering plants diverged from the common ance ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
