Otherwise as in BS-0315. — (2) Culm size dimensions: Basal culm 0.13 m above ground, 2nd internode, culm diameter 3.50 cm, wall thickness 0.50 cm, lumen width 2.50 cm; lower culm 1.15 m above ground, 6th internode, diameter 3.60 cm, wall 0.40 cm, lumen 2.80 cm; mid-culm 3.60 m above ground, diameter 3.20 cm, wall 0.25 cm, lumen 2.70 cm; upper culm 6.30 m above ground, diameter 1.30 cm, wall 0.15 cm, lumen 1.00 cm; culm broken off at 8.00 m above ground, apex supposedly at ca. 10 m.
  • Comments: The plant was sporadically flowering, which perhaps started in early 2016. The flowering was first detected on 24 May 2016 when the flowering branches were already decaying. Further flowering branches in a late stage of development were detected 15 Jan. 2017. Not a single seed was found, no seedlings were found on the ground. The sporadic flowering has not caused any harm to the plant (27 Apr. 2017).
