In probability theory and statistics, variance is the expectation of the squared deviation of a random variable from its population mean or sample mean. Variance is a measure of dispersion, meaning it is a measure of how far a set of numbers is spread out from their average value. Variance has a central role in statistics, where some ideas that use it include descriptive statistics, statistical inference, hypothesis testing, goodness of fit, and Monte Carlo sampling. Variance is an important tool in the sciences, where statistical analysis of data is common. The variance is the square of the standard deviation, the second central moment of a distribution, and the covariance of the random variable with itself, and it is often represented by , , , , or .
Restrepia, abbreviated Rstp in horticultural trade, is a small genus of 50orchids in the orchid family (Orchidaceae), closely related to Pleurothallis. Named in honor of Don Jose Restrepo, it tends to be more showy than most other Pleurothallids. They are found primarily at higher altitudes in the cool, damp montane forests of the Andes and Venezuela, with some into Central America up to southern Mexico.
A heart valve is a one-way valve that allows blood to flow in one direction through the chambers of the heart. Four valves are usually present in a mammalian heart and together they determine the pathway of blood flow through the heart. A heart valve opens or closes according to differential blood pressure on each side.
Clivia miniata, the Natal lily or bush lily, is a species of flowering plant in the genus Clivia of the family Amaryllidaceae, native to woodland habitats in South Africa as well as in Eswatini. 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 the US, particularly California.
Littorina saxatilis, common name the rough periwinkle, is a species of small sea snail, a marine gastropod mollusc in the family Littorinidae, the winkles or periwinkles. First identified in the 1700s, it has been misidentified as a new species 112 times.
Amelanchier sanguinea, known as red-twigged shadbush or roundleaf serviceberry, is a shrub native to eastern and central North America. Its native range stretches from New Brunswick to Saskatchewan south as far as northern Georgia. It is most common in eastern Canada, the northeastern United States, and the Great Lakes region.
Utricularia livida, the leaden bladderwort, is a species of flowering plant in the bladderwort family, native to central and southern Africa, and Mexico. Growing to 50 cm (20 in) tall and broad, it is a carnivorous perennial. It was originally described and published by Ernst Heinrich Friedrich Meyer in 1837.

Chlamys varia, also called Mimachlamys varia common name the variegated scallop, is a species of small scallop, a marine bivalve mollusk in the family Pectinidae, the scallops. It occurs in the North Sea, the English Channel, the northeastern Atlantic Ocean and the Red Sea.
"Die Gattung Nepenthes: Eine monographische Skizze" is a German-language monograph by Günther Beck von Mannagetta und Lerchenau on the tropical pitcher plants of the genus Nepenthes. It was published in 1895 in four parts, spread over the March, April, May and June issues of Wiener Illustrirte Garten-Zeitung.
Chama macerophylla, or the leafy jewel box clam,

Dosinia exoleta, common name the rayed artemis, is a saltwater clam, a marine bivalve mollusc in the family Veneridae, the venus clams.
Iris sanguinea is a rhizomatous flowering plant in the genus Iris and in the series Sibiricae. It is cultivated as an ornamental plant in temperate regions. It is one of the species considered a Japanese iris. It is from Asia, found between Russia, Mongolia, China, Japan and Korea.

Rosa × odorata or Rosa odorata is a hybrid flowering plant of the genus Rosa native to Yunnan in Southwest China, whose taxonomy has been confused. It has been considered a hybrid of Rosa gigantea and Rosa chinensis, or as a quite rare wild species that includes R. gigantea. The wild forms are cultivated to some extent. Cultivars were developed in China in ancient times from R. chinensis crosses, and these have been important in the ancestry of the tea-scented China roses, also called tea roses, and their descendants the hybrid tea roses.
Glenea citrina is a species of beetle in the family Cerambycidae. It was described by James Thomson in 1865. It is known from Laos, Java, Borneo, Malaysia, and Sumatra.
Nepenthes malayensis, or the striped Malayan montane pitcher plant, is a large species of carnivorous tropical pitcher plant native and endemic to eastern mountains of Peninsular Malaysia. The peristomes on both upper and lower pitchers are profusely adorned by reddish bands, or stripes, making the species rather attractive. It grows close to mountain summits around 800–1000 m above sea level in partially shaded areas, though some individuals have been seen striving in open areas. The species was first observed in 2018 and initially thought to be conspecific with N. sanguinea. Nepenthes malayensis formal description was published in late 2020 in Kew Bulletin and it is one of the latest three new Malayan species described in the same year. These discoveries have made Peninsular Malaysia home to 15 species of Nepenthes and there are over 150 species of world's Nepenthes with the majority of these are from the Malay Archipelago.
Drosera citrina is a pygmy sundew, a type of carnivorous plant. It is native to Western Australia. The Latin specific epithet citrina means "lemon coloured", refrring to the colour of the flowers. It is closely related to Drosera nivea, which was considered a variety of D. citrina in the past called Drosera citrina var. nivea
