Rapistrum rugosum (L.) All |
Rapistrum, the bastardcabbages, [1] is a genus of the family Brassicaceae with a distinctive cross like arrangement of its petals. Species of Rapistrum are annual to perennials (Lifespan from 1 to 2 or more years). The yellow petals are accompanied by sepals that stand vertically at near right angles (erecto-patent). Leaf shape and arrangement varies from rough toothed (dentate) to a configuration of opposingly lobed pairs along the plant stalk, pinnately lobed.
The genus Rapistrum has a characteristic fruit comprising two segments:
a) The distal (upper division) The part of the fruit farthest away from the point of attachment. The distal is endowed with a ribbed spheroid base (globose) that tapers to form a narrowed projection. It holds a single seed.
b) The proximal (lower division) The part of the fruit nearest to the point of attachment. Possesses a more uniform narrower shape compared to the distal above, giving the fruit a waist. It holds a maximum of three seeds, more commonly none or one.
The fruit varies from species to species. The distal of R. rugosum is strongly ribbed and narrows to form a beak whereas R. perenne is comparatively less wrinkled and ends with a style that stubbornly resists detachment, 'a persistent style'.
When ripe the distal breaks away in an across-wise fashion, breaking transversely.
The genus Aesculus, with species called buckeye and horse chestnut, comprises 13–19 species of flowering plants in the family Sapindaceae. They are trees and shrubs native to the temperate Northern Hemisphere, with six species native to North America and seven to 13 species native to Eurasia. Several hybrids occur. Aesculus exhibits a classical Arcto-Tertiary distribution.
Crataegus monogyna, known as common hawthorn, one-seed hawthorn, or single-seeded hawthorn, is a species of flowering plant in the rose family Rosaceae. It is native to Europe, northwestern Africa, and West Asia, but has been introduced in many other parts of the world.
Althaea officinalis, the marsh mallow or marshmallow, is a species of flowering plant indigenous to Europe, Western Asia and North Africa, which is used in herbalism and as an ornamental plant. A confection made from the root since ancient Egyptian times evolved into today's marshmallow treat, but most modern marshmallow treats no longer contain any marsh-mallow root.
Teucrium is a cosmopolitan genus of flowering plants in the family Lamiaceae, commonly known as germanders. Plants in this genus are perennial herbs or shrubs, with branches that are more or less square in cross-section, leaves arranged in opposite pairs, and flowers arranged in thyrses, the corolla with mostly white to cream-coloured, lobed petals.
The stigma is the receptive tip of a carpel, or of several fused carpels, in the gynoecium of a flower.
Passiflora lutea, commonly known as yellow passionflower, is a flowering perennial vine in the family Passifloraceae, native to the central and eastern United States. The vine has three-lobed leaves and small, yellowish-green, fringed flowers that appear in the summer, followed by green fruit that turn almost black at maturity. It grows in moist to wet habitats.
Astartea is a genus of flowering plants in the myrtle family, Myrtaceae. The genus is endemic to southwestern Western Australia. The genus name was inspired by Astarte, the Greek name for the goddess Ishtar.
Scandosorbus intermedia or, formerly, Sorbus intermedia, the Swedish whitebeam, is a species of whitebeam found in southern Sweden, with scattered occurrences in Estonia, Latvia, easternmost Denmark (Bornholm), the far southwest of Finland, and northern Poland.
Euphorbia misera is a semi-succulent shrub in the genus Euphorbia commonly known as the cliff spurge or coast spurge. A drought-deciduous shrub, it is typically found as a gnarled, straggly plant occupying seashore bluffs, hills and deserts. Like other members of its genus, it has a milky sap, which can be found exuding out of the light gray bark when damaged. The alternately-arranged leaves are round and folded in the middle, with small hairs on them. The "flowers" can be found blooming year-round, and are colored maroon or yellow in the center with 5 white to light-yellow petal-like appendages attached outside. This species is native to the Baja California peninsula and Sonora in Mexico, and the coast of southern California in the United States, where it is a rare species. It is threatened in some localities by the development of its coastal habitat, which tends to be prime locations for high-end residential and commercial developments.
Succisa pratensis, also known as devil's-bit or devil's-bit scabious, is a flowering plant in the honeysuckle family Caprifoliaceae. It differs from other similar species in that it has four-lobed flowers, whereas small scabious and field scabious have five lobes and hence it has been placed in a separate genus in the same family. It also grows on damper ground.

Rapistrum rugosum is a species of flowering plant in the mustard family known by the common names annual bastardcabbage, common giant mustard or turnipweed. It is native to Eurasia and parts of Africa, and it is present throughout the world as an introduced species and a common weed. It is an invasive species in many areas. It is an annual herb producing an erect stem reaching up to about a meter tall. The leaves are variable in shape and size and the proximal blades are generally cut into lobes or divided into leaflets. The herbage is coated in rough hairs. The inflorescence is a raceme of flowers with dark-veined yellow petals that are each under a centimeter long. The fruit is a knoblike spherical ribbed silique borne on a long pedicel with a widened area where it joins the fruit.
