Question: Acorus and Clivia, are which specific genus?

Context paragraphs:
Iris pseudacorus: Iris pseudacorus (yellow flag, yellow iris, water flag, lever) is a species in the genus "Iris", of the family Iridaceae.  It is native to Europe, western Asia and northwest Africa.  Its specific epithet, meaning "false acorus", refers to the similarity of its leaves to those of "Acorus calamus", as they have a prominently veined mid-rib and sword-like shape.

Clivia: Clivia is a genus of monocot flowering plants native to southern Africa.  They are from the family Amaryllidaceae, subfamily Amaryllidoideae.  Common names are "Natal lily" or "bush lily".

Cubena: Cubena is a genus of moths of the Noctuidae family.  This specific genus of moths is known to display dots on their wings.

Acorus: Acorus is a genus of monocot flowering plants.  This genus was once placed within the family Araceae (aroids), but more recent classifications place it in its own family Acoraceae and order Acorales, of which it is the sole genus of the oldest surviving line of monocots.  Some older studies indicated that it was placed in a lineage (the order Alismatales), that also includes aroids (Araceae), Tofieldiaceae, and several families of aquatic monocots (e.g., Alismataceae, Posidoniaceae).  However, modern phylogenetic studies demonstrate that "Acorus" is sister to all other monocots.  Common names include calamus and sweet flag.

Jobu Formation: The Jobu Formation is a Mesozoic geologic formation.  Dinosaur remains are among the fossils that have been recovered from the formation, although none have yet been referred to a specific genus.  The oldest confirmed tyrannosaurid premaxillary tooth was recovered from the Jobu Formation.

Clivia nobilis: Clivia nobilis (green-tip forest lily), is a species of flowering plant in the genus "Clivia", of the family Amaryllidaceae, native to South Africa.  It grows to about 38 cm .  It has evergreen strap-shaped leaves, and bears pendent umbels of multiple narrow, trumpet-shaped, red and yellow flowers, tipped with green.

Acorus gramineus: Acorus gramineus, commonly known as grass-leaf sweet flag, dwarf sedge, Japanese rush, and Japanese sweet flag, is a botanical species belonging to the genus Acorus, native to Japan, Korea in eastern Asia.  The plant usually grows in wetlands and shallow water.

Clivia miniata: Clivia miniata (Natal lily, bush lily, Kaffir lily) is a species of flowering plant in the genus "Clivia" of the family Amaryllidaceae, native, growing in woodland habitats in South Africa (Eastern Cape, Mpumalanga and KwaZulu-Natal provinces) as well as in Swaziland.  Given suitable conditions it grows into large clumps and is surprisingly water wise.  It is also reportedly naturalized in Mexico.  It is a popular plant for shady areas and is commonly seen growing in older established suburbs in most Australian states.  It is also popular in New Zealand, Japan, China and southern parts of the USA , particularly California.

Acorus calamus: Acorus calamus (also called sweet flag or calamus, among many common names) is a tall perennial wetland monocot of the Acoraceae family, in the genus "Acorus".

Bacillus (shape): A bacillus (plural bacilli) or bacilliform bacterium is a rod-shaped bacterium.  Bacilli are found in many different taxonomic groups of bacteria.  However, the name "Bacillus", capitalized and italicized, refers to a specific genus of bacteria.  The name Bacilli, capitalized but not italicized, can also refer to a less specific taxonomic group of bacteria that includes two orders, one of which contains the genus "Bacillus".  When the word is formatted with lowercase and not italicized, 'bacillus', it will most likely be referring to shape and not to the genus at all.  Bacilliform bacteria are also often simply called rods when the bacteriologic context is clear.
