An inflorescence, in a flowering plant, is a group or cluster of flowers arranged on a stem that is composed of a main branch or a system of branches. An inflorescence is categorized on the basis of the arrangement of flowers on a main axis (peduncle) and by the timing of its flowering.
Juncaceae is a family of flowering plants, commonly known as the rush family. It consists of 8 genera and about 464 known species of slow-growing, rhizomatous, herbaceous monocotyledonous plants that may superficially resemble grasses and sedges. They often grow on infertile soils in a wide range of moisture conditions. The best-known and largest genus is Juncus. Most of the Juncus species grow exclusively in wetland habitats. A few rushes, such as Juncus bufonius are annuals, but most are perennials. Despite the apparent similarity, Juncaceae are not counted among the plants with the vernacular name bulrush.
Cymbidium, commonly known as boat orchids, is a genus of evergreen flowering plants in the orchid family Orchidaceae. Orchids in this genus are epiphytic, lithophytic, terrestrial or rarely leafless saprophytic herbs usually with pseudobulbs. There are usually between three and twelve leaves arranged in two ranks on each pseudobulb or shoot and lasting for several years. From one to a large number of flowers are arranged on an unbranched flowering stem arising from the base of the pseudobulb. The sepals and petals are all free from and similar to each other. The labellum is significantly different from the other petals and the sepals and has three lobes. There are about fifty-five species and sixteen further natural hybrids occurring in the wild from tropical and subtropical Asia to Australia. Cymbidiums are well known in horticulture and many cultivars have been developed. The genome of Cymbidium mannii has been sequenced to study epiphytism and crassulacean acid metabolism.
A frost flower or ice flower is formed when thin layers of ice are extruded from long-stemmed plants in autumn or early winter. The thin layers of ice are often formed into exquisite patterns, curling into "petals" which resemble flowers.
Habenaria, commonly called rein orchids or bog orchids, is a widely distributed genus of orchids in the tribe Orchideae. About 880 species of Habenaria have been formally described. They are native to every continent except Antarctica, growing in both tropical and subtropical zones.
This page provides a glossary of plant morphology. Botanists and other biologists who study plant morphology use a number of different terms to classify and identify plant organs and parts that can be observed using no more than a handheld magnifying lens. This page provides help in understanding the numerous other pages describing plants by their various taxa. The accompanying page—Plant morphology—provides an overview of the science of the external form of plants. There is also an alphabetical list: Glossary of botanical terms. In contrast, this page deals with botanical terms in a systematic manner, with some illustrations, and organized by plant anatomy and function in plant physiology.
Sarcochilus, commonly known as butterfly orchids or fairy bells is a genus of about twenty species of flowering plants in the orchid family, Orchidaceae. Plants in this genus are epiphytes or lithophytes and usually have short stems, leaves arranged in two rows, and flowers arranged along unbranched flowering stems. Most species are endemic to Australia but some are found in New Guinea and New Caledonia.
Draba cuneifolia is a species of flowering plant in the family Brassicaceae known as the wedgeleaf draba or wedgeleaf whitlow-grass. This annual plant is native to the southern half of North America where it grows in open, rocky fields and other disturbed areas. The plant forms a basal cluster of leaves, which are thick, widely toothed, and coated in stiff hairs. It bolts one or more erect stems which may approach 40 centimeters in maximum height. Each hairy stem bears an inflorescence of up to 75 small white flowers that continue at intervals down the stem as the stem grows in height. This family and its plants are easy to identify with its 4 petals and 4 sepals arranged like a "cross", either in an "X" or "H" shape, thus the name "Cruciferae". Mustards have 6 stamens usually 4 are taller and 2 are shorter. Fruits are either a long thin silique or short often rounded silicle.
Oenothera suffrutescens is a species of flowering plant in the evening primrose family known as scarlet beeblossom and scarlet gaura.
Laccosperma is a clustering genus of flowering plant in the family palm found in tropical Africa. Poorly studied and rarely cultivated, they are closely related to the genus Eremospatha and with it form a tribe in the Calameae characterized by dyads of hermaphrodite flowers. The genus name combines the Greek words for "reservoir" and "seed".
Kelloggia galioides is a species of flowering plant in the coffee family known by the common name milk kelloggia. It is a perennial herb that is native to the Western United States.
Zeltnera muehlenbergii is a species of annual herb commonly known as Monterey centaury and Muhlenberg's centaury. It is native to western North America from British Columbia to California and Nevada, where it commonly grows in forests and other moist places. This is an annual herb growing thin, erect, branching stems to heights anywhere between 10 centimeters and one meter. Oval-shaped leaves are arranged oppositely on the stem and are up to 2 or 3 centimeters long. The branching inflorescence bears many flowers, each with small bracts at its base. The flower has five oval-shaped petallike lobes each a few millimeters long.

Terms of plant morphology are included here as well as at the more specific Glossary of plant morphology and Glossary of leaf morphology.

Eriogonum rixfordii is an uncommon species of wild buckwheat known by the common name pagoda buckwheat. It is native to the Mojave Desert, where it grows in California's Death Valley and adjacent parts of Nevada.
Gilia leptantha is a species of flowering plant in the phlox family known by the common name fineflower gilia.
Erythranthe inconspicua, synonym Mimulus inconspicuus, is an uncommon species of monkeyflower known by the common name smallflower monkeyflower.
Pectocarya platycarpa is a species of flowering plant in the borage family known by the common names broadfruit combseed and wide-toothed pectocarya. It is native to the southwestern United States and northwestern Mexico, where it grows in many types of coastal and inland habitat, from mountains to desert. This is an annual herb producing a slender, rough-haired stem, generally upright to erect in form to a maximum height of 25 centimeters. The small, pointed linear leaves are alternately arranged, widely spaced along the stem. The inflorescence is a series of flowers, each on a curved pedicel. The flower has small green sepals and a tiny white corolla. The fruit is an array of four flattened, slightly curving nutlets lined with thin teeth.
Taeniophyllum, commonly known as ribbon roots or 带叶兰属 is a genus of about 240 species of epiphytic or lithophytic plants from the orchid family, Orchidaceae. Plants in this genus are more or less leafless with a very short stem and roots that are often flat, green and photosynthetic. The flowers are small, short-lived, flat or tube-shaped and arranged on short, thin flowering stems. Orchids in this genus are found in Africa, tropical and subtropical Asia, New Guinea, Australia and some Western Pacific Islands. It is extinct in Malawi.
Saccolabiopsis, commonly known as pitcher orchids, is a genus of flowering plants from the orchid family, Orchidaceae. Plants in this genus are small epiphytes with short, fibrous stems, smooth, thin roots, a few thin, oblong to lance-shaped leaves in two ranks and large numbers of small green flowers on an unbranched flowering stem. There are about fifteen species found from the eastern Himalayas to the south-west Pacific.
Hypericum sechmenii, or Seçmen's St John's wort, is a rare species of flowering plant of the St John's wort family (Hypericaceae) that is found in the Eskişehir Province of central Turkey. It was first described in 2009 by Turkish botanists Atila Ocak and Onur Koyuncu, who named the species in honor of Özcan Seçmen, a fellow botanist. They assigned the species to the genus Hypericum, and Norman Robson later placed H. sechmenii into the section Adenosepalum.
