Word: folium Part of Speech: noun Etymology: From Latin folium (“leaf”). Doublet of foil and folio, distantly also with phyllo and phyllon. 1. A leaf. Labels: countable, rare, uncountable Example: 278.0 common walnut-tree folium Example: In conclusion, under the recommended use conditions Uva-ursi folium is a safe therapeutic option for treating lower urinary tract infections. 2. A leaf (2 pages) of a codex or manuscript. Labels: countable, uncountable Example: But Barwick and Robinson both investigated V, and inform us that V leaves almost a full folium vacant (only the first two lines of folium 227 being occupied by the text before the lacuna). Example: However, the columns of the uncial manuscripts should be seen as elements in a text block on the folium for they betray the cannons in vogue for writing the codex as it is possible to verify from a continuing tradition. 3. A document that acts as the legal record of a transaction. Labels: countable, uncountable Example: Giving tallies was a royal mode of contracting debts by our early sovereigns, as Exchequer bills have been the means of raising loans in our times: indeed, the Exchequer bill was the counter-tally, or folium of the tally; and the court of Exchequer has existed in its late order since the days of Edward I., by whom it was regulated and reduced from the institution of the ancient Norman Exchequer, introduced here by William the Conqueror. 4. A document that acts as the legal record of a transaction. Labels: countable, especially, uncountable Example: There may nevertheless be a separate certificate and folium for any derived estate deed. Example: When this occurs, the existing declaration of title or conveyance is cancelled, the existing folium of the record closed, a fresh declaration of title issued to the new proprietor, and a new folium opened in the record book, upon which are carried forward the memorials of all lesser estates, interests, and charges affecting the land, and continuing current at the time of recording the change of ownership of the freehold. 5. A thin sheet or plate of a foliated rock or mineral. Labels: countable, uncountable Example: By varying the supposed angle of the tilt, our previously inclined folia can be thrown into any angle between 26 degrees, which is the least possible angle, and 90 degrees; but if a small inclination be thus given to them, their point of dip will depart far from the north, and therefore not accord with the actual position of the folia of mica-schist on our granitic range. Example: The folia of quartz are longer, thinner, and more uniform in thickness. 6. A lobe on a branching structure. Labels: countable, uncountable Example: The folia of these project considerably beyond the level of the soft cœnenchyma, and produce a very rugose appearance. Example: The folium represents the second largest gross morphologic unit of the human kidney in those protolobes that are undivided and the third largest unit in subdivided protolobes in which the lobes are present. 7. A lobe on a branching structure. Labels: countable, uncountable Example: The vermis portion of lobule C₃ remains small, and still consists of only one folium. Example: These diverge so sharptly from each other that they almost form a right angle with the parent stem, and they run parallel to the long axis of the folium, threading their way between the branches of the various dendritic planes of the cells of Purkinje and entering into contact association with them. 8. A curve of the third order, consisting of two infinite branches having a common asymptote. The curve has a double point, and a leaf-shaped loop. Labels: countable, uncountable Example: These circular cubics are Newton's defective hyperbolae, with a diameter, species 39, 41, 45; the ampullate cubic represents the folium of the unipartite quartic, and the ampaniform the bipartite quartic. Example: I have argued that the real threat the Unruh effect poses to fundamental partical interpretation lies in its suggestion that physically reasonable states outrun the folium of any single irreducible Fock space representation. 9. Synonym of turnsole (“purple dye”). Labels: uncountable Example: Folium is thus described . "Folium is used for dying cloths and is a red colour, and another kind is purple, and another is blue.

Labels: countable, uncountable Example: The folium of silvatica has a row of oblique black markings along the edge on each side, while in angulata it is evenly notched. Example: Abdomen subovate to subtriangular, longer than wide, dorsum with an inverted Christmas tree-like folium of brown and chalk-white bands, cardiac area brown, serving as Christmas tree base.
