(c) The cone bearing the seeds and fibers. The cone is about 8.5 cm in length. The end with fibers without seeds indicate attachment region on the stem and has shortest fibers (2.5-3.0 cm). The fibers on the other end are largest (4-4.5 cm).
(d) Withering of the petals and initiation of fruit development.
(e) Mature opened fruit indicating the outer integument, spongy layer, inner integument and the cone bearing the fibers.
(f) The fiber length at the distal end region of the cone.
