Ferns
$19.00 – $400.00A fern is a member of a group of vascular plants that reproduce via spores and have neither seeds nor flowers. They differ from mosses by being vascular, i.e., having certain tissue that conducts water and nutrients, and having branched stems. Like other vascular plants, ferns have leaves, and these are “megaphylls”, which are more complex than the “microphylls” of clubmosses. Most ferns are leptosporangiate ferns, sometimes termed “true ferns”; they produce what are called “fiddleheads” that uncoil and expand into fronds.[3] The group includes about 10,560 known extant species.[4]

Salvinia Fern
$19.00 – $400.00Salvinia, a genus in the family Salviniaceae, is a floating fern named in honor of Anton Maria Salvini, a 17th-century Italian scientist. Watermoss is a common name for Salvinia.[1] The genus was published in 1754 by Jean-François Séguier, in his description of the plants found round Verona, Plantae Veronenses[2] Twelve species are recognized, at least three of which (S. molesta, S. herzogii, and S. minima) are believed to be hybrids, in part because their sporangia are found to be empty.

Cicada
$19.00 – $400.00The cicadas (/sɪˈkɑːdə/ or /sɪˈkeɪdə/) are a superfamily, the Cicadoidea, of insects in the order Hemiptera (true bugs). They are in the suborder Auchenorrhyncha,[a] along with smaller jumping bugs such as leafhoppers and froghoppers. It is divided into the Tettigarctidae, with two species in Australia, and Cicadidae, with more than 1,300 species described from around the world; many undescribed species remain.
Spider Wasp, Mansfield CT
$19.00 – $400.00Wasps in the family Pompilidae are commonly called spider wasps or pompilid wasps.[1]The family is cosmopolitan, with some 5,000 species in six subfamilies.[2] All species are solitary, and most capture and paralyze prey, though members of the subfamily Ceropalinae are cleptoparasites of other pompilids, or ectoparasitoids of living spiders.[3]
In South America, species may be referred to colloquially as marabunta or marimbondo, though these names can be generally applied to any very large stinging wasps. Furthermore, in some parts of Venezuela and Colombia, it is called matacaballos, or “horse killers”, while in Brazil some particular bigger and brighter species of the general marimbondo kind might be called fecha-goela, or “throat locker”.
Eyeliner
$19.00 – $400.00Eye liner was first used in Ancient Egypt and Mesopotamia as a dark black line around the eyes. As early as 10,000 BC, Egyptians and Mo wore various cosmetics including eye liner not only for aesthetics but to protect the skin from the desert sun. Research has also speculated that eye liner was worn to protect the wearer from the evil eye. The characteristic of having heavily lined eyes has been frequently depicted in ancient Egyptian art. They produced eye liner with a variety of materials, including copper ore and antimony. Ancient Egyptian kohl contained galena, which was imported from nearby regions in the Land of Punt, Coptos and Western Asia.[1]
In the 1920s, Tutankhamun‘s tomb was discovered, introducing the use of eye liner to the Western world. The 1920s were an era commonly associated with many changes in women’s fashion, and women felt freer to apply make-up more liberally.
In the 1960s, liquid eye liner was used to create thick black and white lines around the eyes in the make-up fashion associated with designers like Mary Quant.

No. 2 Pencil
$19.00 – $400.00Many pencils across the world, and almost all in Europe, are graded on the European system using a continuum from H (commonly interpreted as “hardness”) to B (commonly “blackness”), as well as F (usually taken to mean “fineness”, although F pencils are no more fine or more easily sharpened than any other grade. also known as “firm” in Japan[45]). The standard writing pencil is graded HB.[46]
According to Petroski, this system might have been developed in the early 20th century by Brookman, an English pencil maker. It used B for black and H for hard; a pencil’s grade was described by a sequence or successive Hs or Bs such as BB and BBB for successively softer leads, and HH and HHH for successively harder ones.[47]
The Koh-i-Noor Hardtmuth pencil manufacturers claim to have originated the HB standard of gradations, with H standing for Hardtmuth, B for the company’s location of Budějovice, and F for Franz Hardtmuth, who was responsible for technological improvements in pencil manufacture.[48][49]
Beneath the Lens
$19.00 – $400.00In optical engineering, the objective is the optical element that gathers light from the object being observed and focuses the light rays to produce a real image. Objectives can be a single lens or mirror, or combinations of several optical elements. They are used in microscopes, telescopes, cameras, slide projectors, CD players and many other optical instruments. Objectives are also called object lenses, object glasses, or objective
Insect Pinhead
$19.00 – $400.00Insect collecting refers to the collection of insects and other arthropods for scientific study or as a hobby. Because most insects are small and the majority cannot be identified without the examination of minute morphological characters, entomologists often make and maintain insect collections. Very large collections are conserved in natural history museums or universitieswhere they are maintained and studied by specialists. Many college courses require students to form small collections. There are also amateur entomologists and collectors who keep collections.
Dollar Bill at 10x
$19.00 – $400.00A currency (from Middle English: curraunt, “in circulation”, from Latin: currens, -entis) in the most specific use of the word refers to money in any form when in actual use or circulation as a medium of exchange, especially circulating banknotes and coins.[1][2]A more general definition is that a currency is a system of money (monetary units) in common use, especially in a nation.[3] Under this definition, US dollars, British pounds, Australian dollars, and European euros are examples of currency. These various currencies are recognized stores of value and are traded between nations in foreign exchange markets, which determine the relative values of the different currencies.[4] Currencies in this sense are defined by governments, and each type has limited boundaries of acceptance.
