Riella Helicophylla
''Riella'' is a genus in the liverwort family Riellaceae, and includes about eighteen species. Plants in the genus are small and grow submerged in shallow temporary pools. Although the genus is widely distributed in the Northern Hemisphere, locating populations is often difficult. Its occurrence is sporadic and local, and the tiny plants are ephemeral. The ornamented spores remain viable for several years, allowing the plants to survive annual drying of their habitat. The plants are easily grown in laboratory cultures. Description ''Riella'' plants are small, usually or less, and thalloid, with an appearance like an immature alga. The plant consists of an erect central axis ("stem") that is commonly forked, but only sparingly, and the plants are bright green. The stem bears a thin dorsal lamina or "wing", which being on only one side gives the plant an asymmetrical appearance. This lamina is ruffled or undulate.

Camille Montagne
Jean Pierre François Camille Montagne (15 February 1784 – 5 December 1866) was a French military physician and botanist who specialized in the fields of bryology and mycology. He was born in the commune of Vaudoy in the department of Seine-et-Marne. At the age of 14, Montagne joined the French navy, and took part in Napoleon's invasion of Egypt. In 1802 he returned to France to study medicine, and two years later became a military surgeon. In 1832, at the age of 48 he retired from military service to concentrate on the study of cryptogams ( mosses, algae, lichens and fungi). In 1853 he was elected a member of the Académie des sciences. In 1845 he was one of the first scientists (with Marie-Anne Libert) to provide a description of ''Phytophthora infestans'', a potato blight fungus he referred to as ''Botrytis infestans''. Montagne is also known for investigations of mycological species native to Guyane. He contributed numerous articles to the ''Archives de Botanique'' and the ...

South Africa
South Africa, officially the Republic of South Africa (RSA), is the southernmost country in Africa. It is bounded to the south by of coastline that stretch along the South Atlantic and Indian Oceans; to the north by the neighbouring countries of Namibia, Botswana, and Zimbabwe; and to the east and northeast by Mozambique and Eswatini. It also completely enclaves the country Lesotho. It is the southernmost country on the mainland of the Old World, and the second-most populous country located entirely south of the equator, after Tanzania. South Africa is a biodiversity hotspot, with unique biomes, plant and animal life. With over 60 million people, the country is the world's 24th-most populous nation and covers an area of . South Africa has three capital cities, with the executive, judicial and legislative branches of government based in Pretoria, Bloemfontein, and Cape Town respectively.

Riella Halophila
''Riella'' is a genus in the liverwort family Riellaceae, and includes about eighteen species. Plants in the genus are small and grow submerged in shallow temporary pools. Although the genus is widely distributed in the Northern Hemisphere, locating populations is often difficult. Its occurrence is sporadic and local, and the tiny plants are ephemeral. The ornamented spores remain viable for several years, allowing the plants to survive annual drying of their habitat. The plants are easily grown in laboratory cultures. Description ''Riella'' plants are small, usually or less, and thalloid, with an appearance like an immature alga. The plant consists of an erect central axis ("stem") that is commonly forked, but only sparingly, and the plants are bright green. The stem bears a thin dorsal lamina or "wing", which being on only one side gives the plant an asymmetrical appearance. This lamina is ruffled or undulate.

Adolf Engler
Heinrich Gustav Adolf Engler (25 March 1844 – 10 October 1930) was a German botanist. He is notable for his work on alpha taxonomy, plant taxonomy and phytogeography, such as ''Die natürlichen Pflanzenfamilien'' (''The Natural Plant Families''), edited with Karl Anton Eugen Prantl, Karl A. E. von Prantl. Even now, his system of plant classification, the Engler system, is still used by many Herbarium, herbaria and is followed by writers of many manuals and Flora (plants), floras. It is still the only system that treats all 'plants' (in the wider sense, algae to flowering plants) in such depth. Engler published a prodigious number of taxonomic works. He used various artists to illustrate his books, notably Joseph Pohl (1864–1939), an illustrator who had served an apprenticeship as a wood-engraver. Pohl's skill drew Engler's attention, starting a collaboration of some 40 years. Pohl produced more than 33 000 drawings in 6 000 plates for ''Die naturlichen Pflanzenfamilien''. He ...
