Ipomopsis Polycladon
''Ipomopsis polycladon'' is a species of flowering plant in the phlox family known by the common name manybranched ipomopsis. It is native to much of the western United States and northern Mexico, where it grows in sandy soils such as those of the deserts. This is an annual herb producing a number of horizontal red stems extending outward from the short central stem. Leaves appear at the ends and axils of branches. Each leaf is multilobed, and mostly green but often red-tipped, and less than 2 centimeters long. Stems and leaves are covered with woolly glandular hairs. The long stem branches bear inflorescences of leaflike bract In botany, a bract is a modified or specialized leaf, especially one associated with a reproductive structure such as a flower, inflorescence axis or cone scale. Bracts are usually different from foliage leaves. They may be smaller, larger, or of ...s which are green with sharp-pointed red tips, and tiny white flowers a few millimeters across. External ...

John Torrey
John Torrey (August 15, 1796 – March 10, 1873) was an American botany, botanist, chemist, and physician. Throughout much of his career, he was a teacher of chemistry, often at multiple universities, while he also pursued botanical work, focusing on the flora of North America. His most renowned works include studies of the New York flora, the Mexican Boundary, the Pacific railroad surveys, and the uncompleted ''Flora of North America''. Biography Torrey was born in New York City, the second child of Capt. William and Margaret (née Nichols) Torrey.Robbins, C. C. (1968). John Torrey (1796–1873), His Life & Times.

When he was 15 or 16, his father received an appointment to the state prison at Greenwich Village, New York, where he was tutored by Amos Eaton, then a pri ...

Verne Edwin Grant
Verne Edwin Grant (1917-2007) was an American botanist Botany, also called , plant biology or phytology, is the science of plant life and a branch of biology. A botanist, plant scientist or phytologist is a scientist who specialises in this field. The term "botany" comes from the Ancient Greek wo ... and writer. Grant was born in San Francisco, California. In 1940 he received his BA in Botany and in 1949 his PhD in Botany and Genetics from the University of California, Berkeley. He was the Professor of Botany for the University of Texas at Austin from 1970 to 1987. His book ''The Origins of Adaptations'' (1963) discussed the main themes of the modern synthesis such as genetic drift, modes of speciation, natural selection and population genetics. However, Grant did not describe these mechanisms of evolution as " Neo-Darwinism" or the synthetic theory, instead he referred to these mechanisms as the "causal theory." The book was awarded the 1964 Phi Beta Kappa Award i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gilia
''Gilia'' is a genus of between 25 and 50 species of flowering plants in the Polemoniaceae family and is related to phlox. These Western native plants are best sown in sunny, well-draining soil in the temperate and tropical regions of the Americas, where they occur mainly in desert or semi-desert habitats They are summer annuals, rarely perennials, growing to 10–120 cm tall. The leaves are spirally arranged, usually pinnate (rarely simple), forming a basal rosette in most species. The flowers are produced in a panicle, with a five-lobed corolla, which can be blue, white, pink or yellow. ''Gilia'' species are used as food plants by the larvae of some Lepidoptera species including ''Schinia aurantiaca'' and ''Schinia biundulata ''Schinia biundulata'' is a moth of the family Noctuidae. It is found in western North America, including Arizona, California, Idaho, Nevada, Oregon, Texas and Utah. The wingspan is 20–22 mm. Food ''Gilia cana'' is used as an ...

Polemoniaceae
The Polemoniaceae (Jacob's-ladder or phlox family) are a family of flowering plants consisting of about 25 genera with 270–400 species of annuals and perennials native to the Northern Hemisphere and South America, with the center of diversity in western North America. Only one genus (''Polemonium'') is found in Europe, and two (''Phlox'' and ''Polemonium'') in Asia, where they are confined to cool temperate to arctic regions; both genera also occur more widely in North America, suggesting relatively recent colonization of the Old World from North America. The family can be distinguished from most other eudicot families by the ovary made up of three fused carpels (usually with three chambers, but with one chamber in some species). The members of the family have five sepals, five petals fused, and five stamens that alternate with the lobes of the corolla. For decades, most sources used a classification of the family published by Grant in 1959, but new evidence, including mol ...

Inflorescence
An inflorescence is a group or cluster of flowers arranged on a stem that is composed of a main branch or a complicated arrangement of branches. Morphologically, it is the modified part of the shoot of seed plants where flowers are formed on the axis of a plant. The modifications can involve the length and the nature of the internodes and the phyllotaxis, as well as variations in the proportions, compressions, swellings, adnations, connations and reduction of main and secondary axes. One can also define an inflorescence as the reproductive portion of a plant that bears a cluster of flowers in a specific pattern. The stem holding the whole inflorescence is called a peduncle. The major axis (incorrectly referred to as the main stem) above the peduncle bearing the flowers or secondary branches is called the rachis. The stalk of each flower in the inflorescence is called a pedicel. A flower that is not part of an inflorescence is called a solitary flower and its stalk is al ...

Bract
In botany, a bract is a modified or specialized leaf, especially one associated with a reproductive structure such as a flower, inflorescence axis or cone scale. Bracts are usually different from foliage leaves. They may be smaller, larger, or of a different color, shape, or texture. Typically, they also look different from the parts of the flower, such as the petals or sepals. A plant having bracts is referred to as bracteate or bracteolate, while one that lacks them is referred to as ebracteate and ebracteolate, without bracts. Variants Some bracts are brightly-coloured and serve the function of attracting pollinators, either together with the perianth or instead of it. Examples of this type of bract include those of ''Euphorbia pulcherrima'' (poinsettia) and ''Bougainvillea'': both of these have large colourful bracts surrounding much smaller, less colourful flowers. In grasses, each floret (flower) is enclosed in a pair of papery bracts, called the lemma (lower bract) and p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
