Hygrophila, commonly known as swampweeds, is a genus of flowering plants in the acanthus family, Acanthaceae.
 There are about 80 to 100 species, of which many are aquatic plants.
 The genus is distributed across the tropical and subtropical world.
 It is one of only two genera in its family that contains aquatic plants, the other being "Justicia".
 The genus is treated in the tribe "Hygrophileae", which is noted as being in need of revision at the genus level, meaning the current taxonomic boundaries of "Hygrophila" are likely to change in the future.
Hygrophila polysperma, commonly known as dwarf hygrophila, dwarf hygro, Miramar weed, Indian swampweed or Indian waterweed, is an aquatic plant in the acanthus family.
 It is native to Bangladesh, India, China and Malaysia, and has also been introduced to the US states of Florida, Texas and possibly Virginia.
Homalocladium platycladum (centipede plant, tapeworm plant or ribbonbush) is a plant in the knotweed family from New Guinea and the Solomon Islands.
 It is the sole species in the genus Homalocladium.
Callicoma, is a plant genus that contains just one species, Callicoma serratifolia, a tall shrub or small tree which is native to Australia.
 "Callicoma serratifolia" is commonly known as black wattle, derived from the similarity of the flowers to those of Australian "Acacia", which are commonly known as wattles.
 The species has a number of other common names include callicoma, butterwood, silver leaf, silver-leaf butterwood and wild quince.
Hygrophila auriculata (Sanskrit: "gokaṇṭa", "kokilākṣa") is a herbaceous, medicinal plant in the acanthus family that grows in marshy places and is native to tropical Asia and Africa.
 In India it is commonly known as or "gokulakanta" in Sri Lanka as "neeramulli".
Ficus coronulata, commonly known as the peach-leaf fig, is one of several fig species commonly known as sandpaper fig.
 It is native to Western Australia and the Northern Territory.
Acroloxidae, commonly known as river limpets, are a taxonomic family of very small, freshwater snails, aquatic pulmonate gastropod limpet-like mollusks with a simple flattened conical shell in the clade Hygrophila.
Hygrophila corymbosa, commonly known as temple plant, starhorn or giant hygro, is an aquatic plant in the acanthus family.
 It is native to South East Asia, but is grown worldwide in tropical aquariums.
 The plant naturally grows as an emergent, but it can survive long periods fully submerged.
Hygrophila difformis, commonly known as water wisteria (though it is not closely related to true wisteria), is an aquatic plant in the acanthus family.
 It is found in marshy habitats on the Indian subcontinent in Bangladesh, Bhutan, India and Nepal.
 It grows to a height of 20 to 50 cm with a width of 15 to 25 cm.
The shannon (symbol: Sh), more commonly known as the "bit", is a unit of information and of entropy defined by IEC 80000-13.
 One shannon is the information content of an event occurring when its probability is one half.
 It is also the entropy of a system with two equiprobable states.
 If a message is made of a sequence of bits, with all possible bit strings being equally likely, the message's information content expressed in shannons is equal to the number of bits in the sequence.
 For this and historical reasons, the shannon is more commonly known as the bit.
 The introduction of the "shannon" term provides an explicit distinction between the amount of information that is expressed and the quantity of data that may be used to represent the information.
