Vangueria Schumanniana
''Vangueria'' is a genus of flowering plants in the family Rubiaceae. The genus is named for , as '' V. madagascariensis'' is known in Malagasy. Distribution The genus contains over 50 species distributed in Africa south of the Sahara with one species occurring in Madagascar ('' V. madagascariensis''). The centre of diversity is in East Africa (Kenya, Tanzania) and they are rare in West Africa. Bacterial leaf symbiosis Endophytic bacteria are housed in the intercellular space of the leaf mesophyll tissue. The presence of these bacteria can only be microscopically ascertained. The bacteria are identified as '' Burkholderia'', which is a genus that is also found in the leaves of other Rubiaceae species. The hypothesis is that these endophytic bacteria provide chemical protection against insect herbivory. Gousiekte Several ''Vangueria'' species - '' V. latifolia'', '' V. pygmaea'', '' V. thamnus'' - are known to cause , a cardiotoxicosis of ruminants characterised by heart failu ...

Notocactus Schumannianus
''Parodia'' is a genus of flowering plants in the family Cactaceae, native to the eastern slopes of the Andes in northwestern Argentina and southwestern Bolivia and in the lowland pampas regions of northeastern Argentina, southern Brazil, eastern Paraguay, and Uruguay. This genus has about 60 species, many of which have been transferred from ''Eriocactus'', ''Notocactus'' and ''Wigginsia''. They range from small globose plants to tall columnar cacti. All are deeply ribbed and spiny, with single flowers at or near the crown. Some species produce offsets at the base. They are popular in cultivation, but must be grown indoors where temperatures fall below . Taxonomy and Systematics The first description was published in 1923 by the Italian-Argentinian botanist Carlos Luis Spegazzini. The genus is named after Domingo Parodi, one of the early investigators of the flora of Paraguay. The type species is ''Echinocactus microspermus''. Anatomical and morphological work by David Ric ...

Psychotria Schumanniana
''Psychotria'' is a genus of flowering plants in the family Rubiaceae. It contains 1,582 species and is therefore one of the largest genera of flowering plants. The genus has a pantropical distribution and members of the genus are small understorey trees in tropical forests. Some species are endangered or facing extinction due to deforestation, especially species of central Africa and the Pacific. Many species, including '' Psychotria viridis'', produce the psychedelic chemical dimethyltryptamine (DMT). Selected species * ''Psychotria abdita'' * ''Psychotria acutiflora'' * ''Psychotria adamsonii'' * ''Psychotria alsophila'' * ''Psychotria angustata'' * ''Psychotria atricaulis'' * '' Psychotria beddomei'' * ''Psychotria bimbiensis'' * ''Psychotria bryonicola'' * ''Psychotria camerunensis'' * ''Psychotria capensis'' * ''Psychotria carronis'' * ''Psychotria carthagenensis'' * ''Psychotria cathetoneura'' * ''Psychotria cernua' * ''Psychotria chalconeura'' * ''Psychotria ...
