Research undertaken in the late 1970s and early 1980s documented 5067 species of which 5041 were angiosperms and the remaining 26 species were gymnosperms. [1] The Terai area has hardwood, bamboo, palm, and sal trees. [2] Notable plants include the garden angelica, Luculia gratissima, Meconopsis villosa, and Persicaria affinis.
The fossil history of flowering plants records the development of flowers and other distinctive structures of the angiosperms, now the dominant group of plants on land.The history is controversial as flowering plants appear in great diversity in the Cretaceous, with scanty and debatable records before that, creating a puzzle for evolutionary biologists that Charles Darwin named an "abominable ...
Angiosperms 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. [8] 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.
Flower of Liriodendron tulipifera, a Mesangiosperm. Mesangiospermae is a clade that contains the majority of flowering plants (angiosperms). Mesangiosperms are therefore known as the core angiosperms, in contrast to the three orders of earlier-diverging species known as the basal angiosperms: Nymphaeales (including water lilies), Austrobaileyales (including star anise), and Amborellales.
The butterflies are mostly gregarious, are fond of following the course of small streams, above which they float up and down, also frequently gambol round high flowering forest-trees and love to settle in the late afternoon on projecting twigs, mostly in pairs, so that one might think they were beginning family life.
Asclepias syriaca, commonly called common milkweed, butterfly flower, silkweed, silky swallow-wort, and Virginia silkweed, is a species of flowering plant. [2] [3] It is native to southern Canada and much of the United States east of the Rocky Mountains, excluding the drier parts of the prairies. [4] It is in the genus Asclepias, the milkweeds ...
