The Echinodontiaceae are a family of crust fungi in the order Russulales. Species of this family, divided amongst two genera—Echinodontium and Laurilia—have a widespread distribution, although they are especially predominant in north temperate zones. They are parasitic or saprobic on wood, and may cause white rot of angiosperms and gymnosperms.

Bulbophyllum sulcatum is a species of orchid in the genus Bulbophyllum.
Ankyloceras is a genus of Early Devonian cephalopods included in the oncocerid family Karoceratidae. The type species, Ankyloceras nesnayamiense named by Zhuravleva, 1974, comes from Nova Zemlya in Russia. Other species have been found in Japan, Morocco, and Russia.
Stereotoceras is a Middle and Upper Devonian genus in the oncocerid family Brevicoceratidae that formed a smooth, depressed, gyroconic shell with the dorsum much flatter that the venter. Sutures are straight ventrally but have dorsal lobes. Growth lines outline a ventral hyponomic sinus but are otherwise transverse. The siphuncle in ventral, nummuloidal, with discrete, irregular, actinosiphonate deposits at the septal foramina.
Cullen plicatum, synonym Psoralea plicata, is a herb species in the genus Psoralea. It is native from northern Africa to north-west India and to South Africa.
Aframomum is a genus of flowering plants in the ginger family, Zingiberaceae. It is widespread across tropical Africa as well as on some islands of the Indian Ocean. It is represented by approximately 50 species. Its species are perennials and produce colorful flowers. Several aromatic species with essential oils present in fruits, seeds, leaves, stems, rhizomes, and other plant parts are either edible or used as medicine in Africa.

Limeum is a genus of flowering plants. It includes 25 species.
