Context paragraphs:
Chiefs Courts Ordinance: The Chiefs Courts Ordinance was a law in the Sudan, passed by the Anglo-Egyptian colonial authorities in 1931.  The law conveyed judicial and political powers to government-recognized chiefs in the southern areas of the country.  The chief were, through this law, charged with tax collection, overseeing infrastructure constructions and administering native areas' of towns and given the authority to issue punishments upon the local population.  Through this law, and the corresponding Native Courts Ordinance for the northern parts of the Sudan, introduced what would be termed the 'Native Administration' by the British colonial system.

Dalbergia melanoxylon: Dalbergia melanoxylon (African blackwood, grenadilla, or mpingo) is a flowering plant in the family Fabaceae, native to seasonally dry regions of Africa from Senegal east to Eritrea and south to the north-eastern parts of South Africa.  The tree is an important timber species in its native areas; it is used in the manufacture of musical instruments and fine furniture.  Populations and genomic resources for genetic biodiversity maintenance in parts of its native range are threatened by over harvesting due to poor or absent conservation planning and by the species' low germination rates.

Native Courts Ordinance: The Native Courts Ordinance was a law in the Sudan, passed by the Anglo-Egyptian colonial authorities in 1932.  The law conveyed judicial and political powers to government-recognized sheikhs in the northern areas of the country.  The sheikhs were, through this law, charged with tax collection, overseeing infrastructure constructions and administering ‘native areas’ and given the authority to issue punishments upon the local population.  Through this law, and the corresponding Chiefs Courts Ordinance for the southern parts of the Sudan, introduced what would be termed the ‘Native Administration’ by the British colonial system.

Sauromatum: Sauromatum is a genus of flowering plants in the family Araceae.  The genus is native to tropical Africa, tropical Asia, and the Arabian Peninsula.  Their inflorescences last for only a few hours to a day and give off an unpleasant smell.  The inflorescence disperses its odor by heating up.

Judeo-Hamedani dialect: The languages spoken by Iranian Jews are often lumped under the term "Judeo-Persian," a broad term that denotes the various forms of Modern Persian written in the Hebrew script.  Native to Iranian Jews, it has also been used by Jews of Afghanistan, Central Asia, and the Chinese Jewish community of Ka'i Feng Fu.  The original use of Judeo-Persian language is documented as early as sixth century B.C., however there are no literary documents that were preserved in this language prior to the eighth century A.D., according to Dariush Gitisetan from Brandeis University (Dariush Gitisetan, 13).  Unfortunately the separation of Jews from their native areas created linguistic differences, giving rise to a large number of mutually incomprehensible dialects of Judeo-Persian.  This is why, according to Habib Borjian, we need to separate Judeo-Hamadan from Judeo Persian(Habib Borjian, 117).  Judeo-Persian shares many features in common with Modern Persian, while still manifesting distinct differences.  According to Gitisetan, these include(Dariush Gitisetan, 13)

Rehmannia: Rehmannia is a genus of six species of flowering plants in the order Lamiales, endemic to China.

North American Native Plant Society: The North American Native Plant Society (NANPS) is a volunteer-operated registered charitable organization concerned with conserving native plants in wild areas and restoring indigenous flora to developed areas.  It is noted for its work in educating business and the public about the benefits of using native plants, and its work in promoting native species through plant sales and seed exchanges has been credited with the resurgence of some species.  It also maintains a list of local native plant societies across the United States and Canada.

Baptisia australis: Baptisia australis, commonly known as blue wild indigo or blue false indigo, is a flowering plant in the family Fabaceae (legumes).  It is toxic.  It is native to much of central and eastern North America and is particularly common in the Midwest, but it has also been introduced well beyond its natural range.  Naturally it can be found growing wild at the borders of woods, along streams or in open meadows.  It often has difficulty seeding itself in its native areas due to parasitic weevils that enter the seed pods, making the number of viable seeds very low.

Tillandsia: Tillandsia is a genus of around 650 species of evergreen, perennial flowering plants in the family Bromeliaceae, native to the forests, mountains and deserts of Central and South America, the southern United States and the West Indies.  They have naturally been established in diverse environments such as equatorial tropical rain forests, high elevation Andes mountains, rock dwelling (saxicolous) regions, and Louisiana swamps, such as Spanish Moss ("T. usneoides"), a species that grows atop tree limbs.  Airplant is a common name for plants in this genus.  Most "Tillandsia" species are epiphytes – i.e. they normally grow without soil while attached to other plants.  Some are aerophytes or "air plants", which have no roots and grow on shifting desert soil.  Generally, the thinner-leafed varieties grow in rainy areas and the thick-leafed varieties in areas more subject to drought.  Most species absorb moisture and nutrients through the leaves from rain, dew, dust, decaying leaves and insect matter, aided by structures called trichomes.

Arizona Native Plant Society: The mission of Arizona Native Plant Society (AZNPS) is to promote knowledge, appreciation, conservation and restoration of Arizona native plants and their habitats, as well as the use of native plants in urban landscapes and gardens.  Among its initiatives are the Plant Atlas Project of Arizona (PAPAZ), which trains AZNPS volunteers in botanical fieldwork; publication of booklets and brochures promoting the use of native plants; compilation and web publication of plant lists for various natural areas of Arizona and northern Mexico; grants for publication assistance and research; and pioneering work in invasive species education and removal.
