Question: Which genus is aquatic, Phylica or Nelumbo?

full_context: Document 1: Nymphaea nouchali: Nymphaea nouchali, often known by its synonym Nymphaea stellata, or by common names blue lotus, star lotus, red and blue water lily, blue star water lily or manel flower is a water lily of genus "Nymphaea". It is native to southern and eastern parts of Asia, and is the national flower of Sri Lanka and Bangladesh. This species is sometimes considered to include the blue Egyptian lotus "Nymphaea caerulea". In the past, taxonomic confusion has occurred, with the name "Nymphaea nouchali" incorrectly applied to "Nymphaea pubescens".
Document 2: Phoenix (plant): Phoenix is a genus of 14 species of palms, native to an area starting from the Canary Islands in the west, across northern and central Africa, to the extreme southeast of Europe (Crete), and continuing throughout southern Asia from Turkey east to southern China and Malaysia. The diverse habitats they occupy include swamps, deserts, and mangrove sea coasts. Most "Phoenix" species originate in semiarid regions, but usually occur near high groundwater levels, rivers, or springs. The genus is unusual among members of the subfamily Coryphoideae, with it and "Arenga" being the only ones with pinnate, rather than palmate leaves.
Document 3: Phyllanthus: Phyllanthus is the largest genus in the flowering plant family Phyllanthaceae. Estimates of the number species in this genus vary widely, from 750 to 1200. "Phyllanthus" has a remarkable diversity of growth forms including annual and perennial herbs, shrubs, climbers, floating aquatics, and pachycaulous succulents. Some have flattened leaflike stems called cladodes. It has a wide variety of floral morphologies and chromosome numbers and has one of the widest range of pollen types of any seed plant genus.
Document 4: Nelumbonaceae: Nelumbonaceae, sometimes called the sacred lotus family, is a family of flowering plants, including the single genus "Nelumbo" with two species, "N. lutea" (North America) and "N. nucifera" (widespread in tropical Asia).
Document 5: Leionema phylicifolium: Leionema phylicifolium, commonly known as alpine phebalium, is a shrub that is endemic to south-eastern Australia. Plants grow to 1.5 metres high and have narrow leaves with recurved edges. Yellow flowers in a cylindrical arrangement appear at the end of branches in spring.
Document 6: Nymphaea: Nymphaea is a genus of hardy and tender aquatic plants in the family Nymphaeaceae. The genus has a cosmopolitan distribution. Many species are cultivated as ornamental plants, and many cultivars have been bred. Some taxa occur as introduced species where they are not native, and some are weeds. Plants of the genus are known commonly as water lilies. The genus name is from the Greek νυμφαια, "nymphaia" and the Latin "nymphaea", which mean "water lily" and were inspired by the nymphs of Greek and Latin mythology.
Document 7: Pistia: Pistia is a genus of aquatic plant in the arum family, Araceae. The single species it comprises, Pistia stratiotes, is often called water cabbage, water lettuce, Nile cabbage, or shellflower. Its native distribution is uncertain, but probably pantropical; it was first discovered from the Nile near Lake Victoria in Africa. It is now present, either naturally or through human introduction, in nearly all tropical and subtropical fresh waterways. The genus name is derived from the Greek word πιστός ("pistos"), meaning "water," and refers to the aquatic nature of the plants.
Document 8: Padma (attribute): Padma ("Nelumbo nucifera", the sacred lotus) is an aquatic plant that plays a central role in Indian religions such as Hinduism, Buddhism, Sikhism, and Jainism. The lotus flower has many different names such as the "Indian Lotus", the "Sacred Lotus", and the "Bean of India".
Document 9: Dracophyllum: Dracophyllum is a genus of plants belonging to the family Ericaceae, formerly Epacridaceae. There are some one hundred or so species in the genus, mostly shrubs but also cushion plants and trees, found in New Zealand, Australia and New Caledonia. The name, "Dracophyllum" or dragon-leaf refers to their strong similarity to the unrelated "Dracaena", sometimes known as dragon tree. Although dicotyledonous, they resemble primitive monocots with their slender leaves concentrated in clumps at the ends of the branches; they are sometimes called grass-trees.
Document 10: Rhodophiala: Rhodophiala is a genus of herbaceous, perennial and bulbous plants in the Amaryllis family (Amaryllidaceae, subfamily Amaryllidoideae). It consists of about 30 South American species distributed in southern Brazil, Argentina, and, specially, in Chile.
Document 11: Phygelius: Phygelius, common names Cape fuchsia or Cape figwort, is a genus of flowering plants in the Scrophulariaceae family, native to wet slopes and banks in southern Africa. They are evergreen shrubs often treated as perennials in colder climates. They bear many pendent tubular flowers over a long period in summer, in shades of white, yellow and red. The vague similarity of the blooms to fuchsias has led to the common name Cape fuchsia, though they are not closely related.
Document 12: Nelumbo: Nelumbo is a genus of aquatic plants with large, showy flowers. Members are commonly called lotus, though "lotus" is a name also applied to various other plants and plant groups, including the unrelated genus "Lotus". Members outwardly resemble those in the family Nymphaeaceae ("water lilies"), but "Nelumbo" is actually very distant to Nymphaeaceae. "Nelumbo" is derived from the Sinhalese word Sinhalese: නෙළුම් "neḷum", the name for the lotus "Nelumbo nucifera".
Document 13: Nelumbo nucifera: Nelumbo nucifera, also known as Indian lotus, sacred lotus, bean of India, Egyptian bean or simply lotus, is one of two extant species of aquatic plant in the family Nelumbonaceae. The Linnaean binomial "Nelumbo nucifera" (Gaertn.) is the currently recognized name for this species, which has been classified under the former names, "Nelumbium speciosum" (Willd.) and "Nymphaea nelumbo", among others. (These names are obsolete synonyms and should be avoided in current works.) This plant is an aquatic perennial. Under favorable circumstances its seeds may remain viable for many years, with the oldest recorded lotus germination being from that of seeds 1,300 years old recovered from a dry lakebed in northeastern China.
Document 14: Malephora: Malephora is a genus of succulent plants in the ice plant family. There are 13 to 17 species in the genus, many of which are known commonly as mesembs. They are native to Africa.
Document 15: Phylica: Phylica is a genus of plants in the family Rhamnaceae. It contains about 150 species, the majority of which are restricted to South Africa, where they form part of the "fynbos ". A few species occur in other parts of southern Africa, and on islands including Madagascar, the Mascarene Islands, Île Amsterdam, Saint Helena, Tristan da Cunha, and Gough Island.
