Quillaja Saponaria 2c
''Quillaja'' is a genus of flowering plants, the only extant genus in the family Quillajaceae with two or three known species. It was once thought to be in the rose family, Rosaceae, but recent research shows it belongs in its own family. The inner bark of the soap bark tree (''Quillaja saponaria, Q. saponaria'') contains saponin, which is a natural soap. Members of this genus are trees that grow to about .

Quillaja Saponaria
''Quillaja saponaria'', the soap bark tree or soapbark, is an evergreen tree in the family Quillajaceae, native to warm temperate central Chile. In Chile it occurs from 32 to 40° South Latitude approximately and at up to 2000 m (6500 ft) above sea level. It can grow to 15–20 m (50–65 ft) in height. The tree has thick, dark bark; smooth, leathery, shiny, oval evergreen leaves 3–5 cm long; white star-shaped flowers 15 mm diameter borne in dense corymbs; and a dry fruit with five follicles each containing 10–20 seeds. Characteristics The inner bark of ''Quillaja saponaria'' can be reduced to powder and employed as a substitute for soap, since it forms a lather with water, owing to the presence of a glycoside saponin, sometimes distinguished as quillaia saponin. It's also applied as an agricultural spray adjuvant. The same, or a closely similar substance, is found in soapwort (''Saponaria officinalis''), in senega root (''Polygala senega'') and in ...

Dakotanthus
''Dakotanthus cordiformis'' is an extinct species of flowering plant from the Cretaceous Western Interior Seaway of North America. History Five-chambered fruit from the Cretaceous Dakota Sandstone were monographed as early as 1874 by Leo Lesquereux for the United States Geological Survey. In 1892, Lesquereux published one such fossil as ''Carpites cordiformis''. James Basinger and David Dilcher (1984) re-examined flower fossils from the Dakota Formation in Nebraska and published them as the "Rose Creek flower", one of the earliest recorded bisexual flowers, after the Rose Creek Pit of the Dakota Formation. In 2018, "Rose Creek flower specimens" were again re-examined and renamed ''Dakotanthus cordiformis'' with a noted similarity to the extant family Quillajaceae Quillajaceae is a family of flowering plants.

Juan Ignacio Molina
Fr. Juan Ignacio Molina (; (June 24, 1740 – September 12, 1829) was a Chilean Jesuit priest, naturalist, historian, translator, geographer, botanist, ornithologist, and linguist. He is usually referred to as Abate Molina (a form of Abbot Molina), and is also sometimes known by the Italian form of his name, Giovanni Ignazio Molina. He was one of the precursors of the theory of the gradual evolution of species, 44 years before Darwin, who repeatedly quoted him in "The Origin of Species". Biography Early years Molina was born at Guaraculén, a big farm located near Villa Alegre (General Captaincy of Chile), where he lived until he was 5 years old. In the current province of Linares, in the Maule Region of Chile. His parents were Agustín Molina and Francisca González Bruna.

Flowering Plant
Flowering plants are plants that bear flowers and fruits, and form the clade Angiospermae (), commonly called angiosperms. The term "angiosperm" is derived from the Greek words ('container, vessel') and ('seed'), and refers to those plants that produce their seeds 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 (). Like gymnosperms, angiosperms are seed-producing plants. They are distinguished from gymnosperms by characteristics including flowers, endosperm within their seeds, and the production of fruits that contain the seeds. The ancestors of flowering plants diverged from the common ancestor of all living gymnosperms before the end of the Carboniferous, over 300 million years ago. The closest fossil relatives of flowering plants are uncertain and contentious. The earliest angiosperm fossils ar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
