Coming back to the experimental flower texture (Figure 2), if we move from the droplet center to the right along a radius, we see one ellipse then a second one then a third one. Approximately, three ellipses (or four at a few locations) are visible whatever the radius that we consider so that we can imagine three circles relating all the apices of the ellipses located at a constant distance from the center. These circles correspond to cones in the 3D space. Therefore for the model, three cones have been represented: one blue cone corresponds to the ellipses which are located close to the center, a green cone for intermediate ellipse positions and a red cone for the ellipses much closer to the boundary of the droplet. The simulation has been made in the Figure 6a,b with three cones of semi-apex angles of 30∘, 45∘ and 60∘, respectively. These values are in reality close to 90∘ but this drawing permits us to explain the model we have in mind. Note also that the differences between the semi-apex angles of the cones are certainly rather small. Looking now to one single cone, all the ellipses which lie on the Figure 6Three cones have been drawn; each cone contains some assembly of mutually tangent ellipses. The virtual branches of the hyperbolae have one point of intersection at the apex S of the droplet (a): top view; (b): side view. generatrices of the cone are mutually tangent. These ellipses respect the law of corresponding cones (l.c.c.). To check this point, let us consider two adjacent tangent ellipses. We check that the line joining the visible focus of one ellipse to the invisible focus (not physical) of the other goes exactly through the tangential point M between the two ellipses. This argument has been used in the book of P. G. De Gennes and J. Prost  in the case of the well known "fan-shaped" texture of C. Williams whose associate drawing is given in Figure 1 of reference . We emphasize that in the "fan-shaped" texture, the physical hyperbolae are merging outwards instead of inwards as in the case of the flower texture. Such analysis in terms of application of the l.c.c has been also checked on a very large number of examples .
