Question: Are Melicytus and Coix both plants?

full_context: Document 1: Melicytus: Melicytus is a genus of flowering plants in the family Violaceae. "Hymenanthera" is a synonym.
Document 2: Melaleuca: Melaleuca is a genus of nearly 300 species of plants in the myrtle family, Myrtaceae, commonly known as paperbarks, honey-myrtles or tea-trees (although the last name is also applied to species of "Leptospermum"). They range in size from small shrubs that rarely grow to more than 1 m (3 ft) high, to trees up to 35 m (100 ft). Their flowers generally occur in groups, forming a “head” or “spike” resembling a brush used for cleaning bottles, containing up to 80 individual flowers. They are superficially like "Banksia" species, which also have their flowers in a spike, but the structures of individual flowers in the two genera are very different.
Document 3: Alopecurus: Alopecurus, or foxtail grass, is a common and widespread genus of plants in the grass family. It is common across temperate and subtropical parts of Eurasia, northern Africa, and the Americas, as well as naturalized in Australia and on various islands.
Document 4: Colocasia: Colocasia is a genus of flowering plants in the family Araceae, native to southeastern Asia and the Indian subcontinent. Some species are widely cultivated and naturalized in other tropical and subtropical regions. Common names include tarul, karkala ko ganu, elephant-ear, taro, cocoyam, dasheen, chembu, champadhumpa, shavige gadde, and eddoe. Elephant-ear and cocoyam are also used for some other large-leaved genera in the Araceae, notably "Xanthosoma" and "Caladium". The generic name is derived from the ancient Greek word "kolokasion", which in the Greek botanist Dioscorides (1st century AD) meant the edible roots of both "Colocasia esculenta" and "Nelumbo nucifera". It is thought that the edible roots of "Colocasia esculenta" have been cultivated in Asia for more than ten thousand years. The species "Colocasia esculenta" is an invasive species in wetlands along the American Gulf coast, where it threatens to displace native wetland plants.
