Taxa described in 1828

Streptocarpus ("twisted fruit" from Greek στρεπτός (streptos) "twisted" and καρπός (karpos) "fruit") is an Afrotropical genus of flowering plants in the family Gesneriaceae. The genus is native to Afromontane biotopes from central, eastern and southern Africa, including Madagascar and the Comoro Islands. The flowers are five-petalled, salverform tubes, almost orchid-like in appearance, and hover or arch over the plant, while the pointed, elongate fruit is of a helical form similar to that of the "tusk" of a narwhal. In the wild, species can be found growing on shaded rocky hillsides or cliffs,

Papionini is a tribe of Old World monkeys that includes several large monkey species, which include the macaques of North Africa and Asia, as well as the baboons, geladas, mangabeys, kipunji, drills, and mandrills, which are essentially from sub-Saharan Africa (although some baboons also occur in southern Arabia). It is typically divided into two subtribes: Macacina for the genus Macaca and its extinct relatives and the Papionina for all other genera.

Grantia is a genus of calcareous sponges belonging to the family Grantiidae. Species of the genus Grantia contain spicules and spongin fibers.

Bucquetia is a genus of plant in family Melastomataceae. It contains the following species:

Pannaria is a genus of lichen-forming fungi in the family Pannariaceae. These lichens form leaf-like, scaly, or crusty patches that typically arrange themselves in loose rosettes on tree bark in humid forests. Most species partner with nitrogen-fixing cyanobacteria, though some contain green algae instead. The genus was established in 1828 and now includes about 80 recognized species found worldwide, particularly in tropical and subtropical regions.

Creseis is a genus of gastropods belonging to the family Creseidae.

Comolia is a genus of flowering plants belonging to the family Melastomataceae.

Pogonornis is a genus of African barbets from the family Lybiidae (formerly included in the Capitonidae and sometimes in the Ramphastidae). This genus ranges across sub-Saharan Africa.

Dictyotaceae is large family of brown algae (class Phaeophyceae). It is the only family in the monotypic order Dictyotales (). Members of this family generally prefer warmer waters than other brown algae and are prevalent in tropical and subtropical waters thanks to their many chemical defenses to ward off grazers. They display an isomorphic haplodiploid life cycle and are characterized by vegetative growth through a single apical cell. One genus in this family, Padina, is the only calcareous member of the brown algae. Lobophora variegata (= Pocockiella varieagata) often presents a beautiful b

Xerotus is a genus of fungi in the family Polyporaceae.

Porinaceae is a family of lichen-forming fungi in the order Gyalectales. While Trichotheliaceae was proposed as an alternative, Porinaceae is the widely accepted name following ongoing nomenclatural discussions. Most members of this family typically have a crust-like appearance and grow on a variety of surfaces, including tree bark, leaves, and rocks. Porinaceae is known for its diverse morphology, ranging from simple crust-like forms to more complex structures with distinct or fan-shaped . Porinaceae species generate small, typically flask-shaped reproductive structures (), which house spores
