Scaevola taccada, also known as beach cabbage, sea lettuce, beach naupaka, naupaka kahakai (Hawaiian), magoo (Divehi), merambong (Malay), bapaceda or papatjeda (Moluccan Islands), ngahu (Tongan) is a flowering plant in the family Goodeniaceae found in coastal locations in the tropical areas of the Indo-Pacific.
 It is a common beach shrub throughout the Arabian Sea, the tropical Indian Ocean and the tropical Islands of the Pacific.
Anacardium is a genus of flowering plants in the family Anacardiaceae, native to tropical regions of the Americas.
The Paleotropical Kingdom (Paleotropis) is a floristic kingdom comprising tropical areas of Africa, Asia and Oceania (excluding Australia and New Zealand), as proposed by Ronald Good and Armen Takhtajan.
 Part of its flora, inherited from the ancient supercontinent of Gondwana or exchanged later (e.g. Piperaceae with pantropical distribution and but few warm temperate representatives), is shared with the Neotropical Kingdom, comprising tropical areas of Central and South America.
 Moreover, the Paleotropical flora influenced the tropical flora of the Australian Kingdom.
 The Paleotropical Kingdom is subdivided into five floristic subkingdoms according to Takhtajan (or three, according to Good) and about 13 floristic regions.
 In this article the floristic subkingdoms and regions are given as delineated by Takhtajan.
Paspalum vaginatum is a species of grass known by many names, including seashore paspalum, biscuit grass, saltwater couch, silt grass, and swamp couch in the English language, grama de costa, grama de mar, gramilla blanca, and gramón in Spanish, herbe rampante in French, and hai que bai () in Chinese.
 It is native to the Americas, where it grows in tropical and subtropical regions.
 It is found throughout the other tropical areas of the world, where it is an introduced species and sometimes an invasive weed.
 It is also cultivated as a turfgrass in many places.
Ferrallitisation is the process in which rock is changed into a soil consisting of clay (kaolinite) and sesquioxides, in the form of hydrated oxides of iron and aluminium.
 In humid tropical areas, with consistently high temperatures and rainfall for all or most of the year, chemical weathering rapidly breaks down the rock.
 This at first produces clays which later also break down to form silica.
 The silica is removed by leaching and the sesquioxides of iron and aluminium remain, giving the characteristic red colour of many tropical soils. Ferrallitisation is the reverse of podsolisation, where silica remains and the iron and aluminum are removed.
 In tropical rain forests with rain throughout the year, ferrallitic soils develop.
 In savanna areas, with altering dry and wet climates, ferruginous soils occur.
Hypoestes is a flowering plant genus with many dozens of species.
 They are widely distributed throughout the tropical and subtropical lands around the Indian Ocean, and some adjacent regions.
Phyllanthus microcladus is a plant found in sub tropical areas of eastern Australia.
 The Brush Sauropus is listed as endangered by extinction.
 It occurs by streams in sub tropical rainforest, from as far south as Grafton, New South Wales to the south east rainforest areas of Queensland.
 Most often seen in the valleys of the Brunswick, Richmond and Tweed Rivers in far north eastern New South Wales.
The red-whiskered bulbul ("Pycnonotus jocosus"), or crested bulbul, is a passerine bird found in Asia.
 It is a member of the bulbul family.
 It is a resident frugivore found mainly in tropical Asia.
 It has been introduced in many tropical areas of the world where populations have established themselves.
 It feeds on fruits and small insects.
 Red-whiskered bulbuls perch conspicuously on trees and have a loud three or four note call.
 They are very common in hill forests and urban gardens within its range.
Hydropus is a genus of fungi in the family Marasmiaceae.
 The widespread genus contains about 100 species, especially in tropical areas, but is not well represented in temperate regions.
 About 15 taxa are found in Europe; "H. floccipus" has the widest distribution in western Europe.
 "Hydropus" was circumscribed by Rolf Singer in 1948.
 Species in the genus have fruit bodies with caps that are mycenoid, collybioid, or omphaloid in form.
 Most species occur in tropical and subtropical regions, where they grow as saprobes on rotting wood, forest litter, and mosses.
 Generally, most "Hydropus" species are rare, and several are known only from the type collection, including "H. conicus", "H. moserianus", "H. nitens", and "H. paradoxus".
Kyllinga brevifolia is a species of sedge known by several common names, including shortleaf spikesedge, green kyllinga, perennial greenhead sedge, and kyllinga weed.
 It is native to tropical areas in the Americas but it can be found in warm regions around the world where it is an introduced species.
 This is a rhizomatous perennial herb growing one to several erect stems to heights up to about half a meter, often much shorter.
 It produces tiny inflorescences of a few spikelets each which in total are less than a centimeter long.
 It is sometimes a weed in wet areas such as cultivated land and irrigation ditches.

Question: Are Hypoestes and Anacardium both found in tropical areas?
Answer: yes
