Varying β (cohesion/gliding ratio). (a) β = 0, the trichomes organize into broad streams where they are locally aligned. The streams narrow in places forming dense clusters of trichomes. Streams bend sharply in some places. The streams appear stable at t = 12 h; (b) β = 0.25, the trichomes organize into thin parallel bands that are roughly globally aligned. The distribution of the trichomes appears stable at t = 12 h; (c) β = 1, the trichomes form a chaotic network of thin bands. No discernible macroscopic pattern is observed; (d) β = 5, virtually all trichomes are banded. The bands are chaotically dynamic, constantly splitting and merging with neighboring bands.
