Haecceitism is the perspective implied by the belief that entities can have haecceity or individual essence, "a set of principles which are essential to it and distinguish it from everything else."
 James Ladyman characterizes haecceitism as "the claim that worlds can differ "solo numero", that worlds can differ "de re" whilst not differing "de dicto", sometimes said, that worlds can differ solely by the permutation of individuals."
Ceratopetalum gummiferum, the New South Wales Christmas Bush, is a tall shrub or small tree popular in cultivation due to its sepals that turn bright red-pink at around Christmas time.
 The petals are actually small and white - it is the sepals that enlarge to about 12mm after the flower sets fruit and starts to dry out.
Ceratopetalum is a genus of nine species of shrub and tree in the family Cunoniaceae.
 They are found along the eastern coast of Australia and extend north to New Guinea.
 Two Australian species are among the best known, one being "C. apetalum" or coachwood, renowned as a timber tree, and "C. gummiferum", the New South Wales Christmas bush, so named as it flowers in December.
Ceratopetalum apetalum, the coachwood, scented satinwood or tarwood, is a medium-sized hardwood tree, straight-growing with smooth, fragrant, greyish bark.
 It is native to eastern Australia in the central and northern coastal rainforests of New South Wales and southern Queensland, where is often found on poorer quality soils in gullies and creeks and often occurs in almost pure stands.
 "C. apetalum" is one of 8 species of "Ceratopetalum" occurring in eastern Australia, New Guinea, New Britain and various islands in the same region.
Fibigia clypeata is an Asian species of flowering plant of the genus "Fibigia" in the mustard family.
 It is native to Iran and the Middle East.
Nano-PSI is a plasma device at the Differ - Dutch Institute For Fundamental Energy Research (DIFFER) research institute in Eindhoven.
 It is used for experimental research at the junction of plasma physics and materials science.
 'PSI' stands for Plasma Surface Interactions, while 'nano' has been chosen to stress the mission of the device to synthesize various nanostructures. Nano-PSI is the belongs to the family of plasma generators at DIFFER, that also hosts the Magnum-PSI and UPP-PSI linear devices.
Chilelopsis calderoni is a species of mygalomorph spiders of Chile, named after Dr Raúl Calderón.
 Males differ from "C. puertoviejo" in the more sinuous distal portion of the bulbal duct; females differ in the spermathecae with a distinct fundus and a narrowed duct.
 Males differ from "C. serena" by the presence of a dense patch of setae on the anterior tibiae, females in the undivided spermathecae.
Fibigia is a flowering plant of the genus "Fibigia" in the family Brassicaceae.
Ceratopetalum succirubrum is a species of plant in the Cunoniaceae family.
 It is found in Australia, West Papua (Indonesia), and Papua New Guinea.
 It is threatened by habitat loss.
The Anisophylleaceae are a small family with four genera and 71 species, in the order Cucurbitales, according to the APG II.
 However, it is more isolated from the other suprafamilal clades in this order, while it shows some similarities in flower morphology with the genus "Ceratopetalum" (family Cunoniaceae, order Oxalidales).
 Several wood features of this family are more primitive than those of the other families in the order Cucurbitales.
