Orobanche Australiana
''Orobanche'', commonly known as broomrape, is a genus of almost 200 species of small parasitic herbaceous plants, mostly native to the temperate Northern Hemisphere. It is the type genus of the broomrape family Orobanchaceae. It is a weed on broadleaf crop plants in Australia, where some states enforce mandatory destruction and reporting, as well as prohibition of sale. Description Broomrapes are generally small, only tall depending on species. They are best recognized by the yellow- to straw-coloured stems completely lacking chlorophyll, bearing yellow, white, or blue snapdragon-like flowers. The flower shoots are scaly, with a dense terminal spike of 10-20 flowers in most species, although single in one-flowered broomrape (''Orobanche uniflora''). The leaves are merely triangular scales. The seeds are minute, tan or brown, blackening with age. These plants generally flower from late winter to late spring. When they are not flowering, no part of the plants is visible above t ...

Orobanche Uniflora
''Orobanche uniflora'', commonly known as one-flowered broomrape, one-flowered cancer root, ghost pipe or naked broomrape, is an annual parasitic herbaceous plant. It is native to much of North America, where it is a parasitic plant, tapping nutrients from many other species of plants, including those in the families Asteraceae and Saxifragaceae and in the genus ''Sedum''. The name "orobanche" can be translated to "vetch-strangler" and "uniflora" can be translated to "single-flower". Description ''Orobanche uniflora'' grows to in height, with one purple-to-white flower with five petals per stem. The corolla is two-lipped, finely fringed with five similar lobes. The main stem is under the ground, with only the pedicels being seen and each pedicel containing only one flower. The stems are grayish tan. No leaves are on the plant or offshoot from it. It reproduces from its seeds, which are produced from fruit that has two sections. Many seeds are produced from the plant's fruit. T ...

Cabbage
Cabbage, comprising several cultivars of '' Brassica oleracea'', is a leafy green, red (purple), or white (pale green) biennial plant grown as an annual vegetable crop for its dense-leaved heads. It is descended from the wild cabbage ( ''B. oleracea'' var. ''oleracea''), and belongs to the " cole crops" or brassicas, meaning it is closely related to broccoli and cauliflower (var. ''botrytis''); Brussels sprouts (var. ''gemmifera''); and Savoy cabbage (var. ''sabauda''). A cabbage generally weighs between . Smooth-leafed, firm-headed green cabbages are the most common, with smooth-leafed purple cabbages and crinkle-leafed savoy cabbages of both colours being rarer. Under conditions of long sunny days, such as those found at high northern latitudes in summer, cabbages can grow quite large. , the heaviest cabbage was . Cabbage heads are generally picked during the first year of the plant's life cycle, but plants intended for seed are allowed to grow a second year and m ...

Orobanche Alba
''Orobanche alba'', also known by its common names thyme broomrape and red broomrape, is a holoparasitic plant of the broomrape family. It parasitises plants from the mint family. It is native to countries across Europe, the Middle East, Asia, and North Africa. As ''Orobanche alba'' is polymorphic and has been relatively poorly studied, there is often uncertainty over taxonomy and classification. Description ''Orobanche alba'' is a short reddish annual with simple flowering stems. They grow between tall. Plants have fragrant flowers, cylindrical campanulate (bell-shaped) corolla with dark glands, and calyx teeth which are usually 'entire' (consisting of a single piece). The plant generally flowers from May to June (though in rare cases it flowering can occur into early September) and is pollinated by bumblebees. Subspecies ''Orobanche alba'' has four accepted infraspecific names: *''Orobanche alba'' subsp. ''alba'': Originally described as ''Orobanche rubra''. It generally ...

Orobanche Aegyptiaca
''Orobanche aegyptiaca'', the Egyptian broomrape, is a plant which is an obligate holoparasite from the family Orobanchaceae with a complex lifecycle. This parasite is most common in the Middle East and has a wide host range including many economically important crops. Selective control of Egyptian broomrape is extremely difficult because the close association between host crop and parasite limits the use of most mechanical and herbicidal approaches. Disease cycle A single Egyptian broomrape plant is capable of producing hundreds of thousands of extremely small ( long) seeds. These seeds, dispersed by the wind, animals, or by more artificial means such as farm machinery, survive in the soil and have the ability to remain viable in the soil for more than 15 years. When the seeds are dropped, they are dormant. They require after-ripening, or further ripening after the seed has fallen from the plant, which is completed by the time the dry season has ended.

Vicia Ervilia
''Vicia ervilia'', called ervil or bitter vetch, is an ancient legume crop of the Mediterranean region. Besides the English names, other common names include: (Persian), (Arabic), (Spanish), (Greek), and (Turkish). According to Zohary and Hopf, this crop is consumed only by the poorest people or in times of famine. Daniel Zohary, Maria Hopf and Ehud Weiss, ''Domestication of Plants in the Old World: The Origin and Spread of Domesticated Plants in Southwest Asia, Europe, and the Mediterranean Basin'', 4th edition (Oxford: University Press, 2012), p. 116 Pliny the Elder states that bitter vetch (''ervum'') has medicinal value like vetch (''vicia''), citing the letters of Augustus where the emperor wrote that he regained his health from a diet of bitter vetch ( N.H. 18.38). The grain is an excellent sheep and cattle feed concentrate. It has been held in high esteem by farmers in the Old World since the beginning of agriculture to improve the nutritional value of bulk feeds ...
