1661Boyle Cert. Physiol. Ess. (1669) 57 My own Laboratory has afforded me divers such parcels of Regulus without Mars (some of which I have yet by me very fairly stellated). c1711Petiver Gazophyl. ix. xc, Its yellow stellated Flowers adhere to the middle rib of a jagged Membrane. 1785Martyn Lett. Bot. xv. (1794) 163 This class comprises another natural order of plants, entitled Stellated, from the manner in which the leaves grow upon the stem. 1788Blagden in Phil. Trans. LXXVIII. 281 When these stellated crystals once began to form. 1804Shaw Gen. Zool. V. 378 Stellated Sturgeon..head subtetragonal and roughened with stellated marks and tubercles. 1821W. P. C. Barton Flora N. Amer. I. 87 Stem and branches..densely beset with stellated hairs. 1859Cayley Math. Papers (1891) IV. 81 The great stellated dodecahedron. 1892Crookes Wagner's Man. Chem. Technol. 203 That stellated crystalline surface which is preferred in trade.
b. Geom. 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. [The sense is due to L. Poinsot, who used F. étoilé in Jrnl. de l'École Polytechn. (1810) IV. 41).]
1859A. Cayley in Phil. Mag. XVII. 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. 1931Proc. Cambr. Philos. Soc. XXVII. 206 Consider..the ‘small stellated dodecahedron’ {ob} , 5{cb}, bounded by pentagrams. 1952Cundy & Rollett Math. 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). 1976I. 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.
