- n. A leaf, esp. a thin leaf or plate.
- n. A curve of the third order, consisting of two infinite branches, which have a common asymptote. The curve has a double point, and a leaf-shaped loop; whence the name. Its equation is x3 + y3 = axy.

- n. A leaf; a lamina; a lamella; a layer.
- n. In geometry, a loop, being a part of a curve terminated at both ends by the same node.

You have got a distinct notion, I hope, of leaf-crystals; and you see the sort of look they have: you can easily remember that 'folium' is Latin for a leaf, and that the separate flakes of mica, or any other such stones, are called
Et venit ad eum columba tempore vespertimo, et ecce, folium olivae raptum erat in ore ejus, et cognovit Noah quod extenuatae essent aquae
"Dicunt aquilam quum in altum volare voluerit ut prospiciat rerum naturas lactucoe sylvaticoe folium evellere et succo ejus sibi oculos tangere, et maximam inde claritudinem accipere."
The plants most limited were Papaveracea, Aconitum folium aconitoideum,
The _folium_ and _uentus_ images of the present line are found together at Prop II ix 33-35 'non sic incerto mutantur flamine Syrtes,/nec folia hiberno tam tremefacta Noto,/quam cito feminea non constat foedus in ira'.
The superior semilunar lobules and the folium vermis form the lobus semilunaris.
This arborescence is not circular, but, like the cell, is flattened at right angles to the long axis of the folium; in other words, it does not resemble a round bush, but has been aptly compared by Obersteiner to the branches of a fruit tree trained against a trellis or a wall.
The superior vermis is subdivided from before backward into the lingula, the lobulus centralis, the monticulus and the folium vermis, and each of these, with the exception of the lingula, is continuous with the corresponding parts of the hemispheresthe lobulus centralis with the alæ, the monticulus with the quadrangular lobules, and the folium vermis with the superior semilunar lobules.
Hence, in sections carried across the folium the arborescence is broad and expanded; whereas in those which are parallel to the long axis of the folium, the arborescence, like the cell itself, is seen in profile, and is limited to a narrow area.
The horizontal branch passes backward to the folium vermis, greatly diminished in size in consequence of having given off large secondary branches; one, from its upper surface, ascends to the clivus monticuli; the others descend, and enter the lobes in the inferior vermis, viz., the tuber vermis, the pyramid, the uvula, and the nodule.
