Table 90 Its yellow stellated Flowers adhere to the middle rib of a jagged Membrane. 1785 T. Martyn tr. J.-J. Rousseau Lett. Elements Bot. xv. 169 This Class comprises another natural order of plants entitled Stellated, from the manner in which the leaves grow upon the stem. 1788 C. Blagden in Philos. Trans.

P. C. Barton Flora N. Amer. (new ed.) I. 87 Stem and branches..densely beset with stellated hairs. 1859 A. Cayley Coll. Math. Papers (1891) IV. 81 The great stellated dodecahedron. 1892 W. Crookes tr. R. von Wagner Man. Chem. Technol. 203 That stellated crystalline surface which is preferred in trade. b. Geometry. [The sense is due to L. Poinsot, who used French étoilé in Jrnl. de l'École Polytechn. (1810) IV. 41).] Of a polygon, polyhedron, or polytope: capable of being generated from a convex polygon, etc., by extending the edges, etc., until they once more meet at a new set of vertices, etc. stellated polygon n. a polygon in which each vertex is not connected to the two adjacent vertices, but to two others, so that the sides cross each other to form a starlike figure, e.g. a pentagram and analogous objects with a higher number of vertices, the variety of forms increasing with the number of vertices, i.e. the number of non-adjacent points to which a vertex can be joined.

Cayley in London, Edinb. & Dublin Philos. Mag. 17 123 It is shown by Poinsot..that, besides the regular polyhedrons of ordinary geometry, there are (of course in an extended signification of the term) four new regular polyhedrons, viz. an icosahedron, which I will call the great icosahedron.., and three dodecahedrons, which I will call the great dodecahedron.., the great stellated dodecahedron.., and the small stellated dodecahedron. 1890 Cent.

Models iii. 83 These four beautiful solids were unknown to the ancient world and were not discovered until modern times. The two with star faces—the two stellated dodecahedra—were found by Kepler (1571–1630); the others with regular faces and star vertices—the great icosahedron and dodecahedron—by Poinsot (1777–1859). 1954 Philos. Trans. (Royal Soc.) A. 246 429 When the edges of the decagons are produced to become edges of decagrams, the edges of the pentagons become edges of pentagrams (the edges of the stellated polygons being in the same ratio to the edges of the original polygons). 1976 I. Lakatos Proofs & Refutations i. 62 Take for instance the ‘great stellated dodecahedron’ (fig. 15). It consists, like the ‘small stellated dodecahedron’ of pentagrams, but differently arranged. It has 12 faces, 30 edges and 20 vertices, so that V − E + F = 2. 2. Studded with stars.
