Plumbaginaceae
Plumbaginaceae is a family of flowering plants, with a cosmopolitan distribution. The family is sometimes referred to as the leadwort family or the plumbago family. Most species in this family are perennial herbaceous plants, but a few grow as lianas or shrubs. The plants have perfect flowers and are pollinated by insects. They are found in many different climatic regions, from arctic to tropical conditions, but are particularly associated with salt-rich steppes, marshes, and sea coasts. The family has been recognized by most taxonomists. The APG II system (2003; unchanged from the APG system of 1998), recognizes this family and assigns it to the order Caryophyllales in the clade core eudicots. It includes ca 30 genera and about 725 species. The 1981 Cronquist system placed the family in a separate order Plumbaginales, which included no other families. The Dahlgren system had segregated some of these plants as family Limoniaceae. Genera *''Acantholimon'' *''Aegialitis'' *'' ...

Ceratostigma
''Ceratostigma'' (;), or leadwort, plumbago, is a genus of eight species of flowering plants in the family Plumbaginaceae, native to warm temperate to tropical regions of Africa and Asia. Common names are shared with the genus ''Plumbago''. Description ''Ceratostigma'' species are flowering herbaceous plants, subshrubs, or small shrubs growing to tall. The leaves are spirally arranged, simple, 1–9 cm long, usually with a hairy margin. Some of the species are evergreen, others deciduous. The flowers are produced in a compact inflorescence, each flower with a five-lobed corolla; flower colour varies from pale to dark blue to red-purple. The fruit is a small bristly capsule containing a single seed. Selected species *''Ceratostigma abyssinicum'' (Hochst.) Schwein. & Asch. *''Ceratostigma griffithii'' C.B.Clarke *''Ceratostigma minus'' Stapf ex Prain *''Ceratostigma plumbaginoides'' (Bunge) *''Ceratostigma ulicinum'' Prain *''Ceratostigma willmottianum'' Stapf Cultivati ...

Plumbago
''Plumbago'' is a genus of 10–20 species of flowering plants in the family Plumbaginaceae, native to warm temperate to tropical regions of the world. Common names include plumbago and leadwort (names which are also shared by the genus '' Ceratostigma''). Description The species include herbaceous plants and shrubs growing to tall. The leaves are spirally arranged, simple, entire, long, with a tapered base and often with a hairy margin. The flowers are white, blue, purple, red, or pink, with a tubular corolla with five petal-like lobes; they are produced in racemes. The flower calyx has glandular trichomes (hairs), which secrete a sticky mucilage that is capable of trapping and killing insects; it is unclear what the purpose of these trichomes is; protection from pollination by way of "crawlers" (ants and other insects that typically do not transfer pollen between individual plants), or possible protocarnivory. Mature plumbago leaves often have a whitish residue on the ...

Minuartia
''Minuartia'' is a genus of flowering plants commonly known as sandworts in the family Caryophyllaceae. Minuartias are small annual or perennial plants which grow in otherwise inhospitable conditions such as on rocky ledges and in stony soil. The genus is widely distributed in the northern hemisphere, mainly distributed in Europe, in the Mediterranean region, and north Africa, southwest Asia, and the Caucasus Mountains. Many ''Minuartia'' species were formerly classed in the genus '' Arenaria'', and the obsolete genus ''Alsine''. In 2014, the polyphyletic ''Minuartia'' ''sensu lato'' was recircumscribed, with many of the species transferred to other genera, including '' Cherleria'', '' Eremogone'', '' Facchinia'', '' Mcneillia'', '' Minuartiella'', '' Mononeuria'', '' Pseudocherleria'', '' Rhodalsine'', '' Sabulina'', and ''Triplateia''. ''Minuartia'' '' sensu stricto'' is characterized by the following features: leaves linear-setaceous; 5 acute sepals with 3, 5, or 9-veins; 5 ...
