Dès que je remet la mains sur les photos de mon Ph Edulis Gracilis...je les mets ici...
Xin Chun Lin, Xiao Sai Ruan, Yong Feng Lou, Xiao Qin Guo and Wei Fang a écrit :We found that the three taxa, P. kwangsiensis, P. nigra var. henonis, and P. pubescens were genetically far from each other, while the cultivars of P. pubescens were genetically similar. Genetic distances between the cultivars indicate genetic similarity among all of the cultivars sampled, but also show diversity among these cultivars.

More than 10 internodes below the middle part of culm are swollen
5
P. pubescens cv. Tao Kiang
Culm has yellow and green vertical stripes; leaves sometimes have yellow stripes
6
P. pubescens cv. Viridisulcata
Culm is yellow but internode sulcus is green
7
P. pubescens cv. Luteosulcata
Culm is green but internode sulcus is yellow
8
P. pubescens cv. Gracilis
Culm is short (7–8 m tall) with a diameter of 3–4 cm; wall of culm is thick
9
P. pubescens cv. Obliquinoda
Culm is slender; adjacent nodes are alternately oblique
10
P. pubescens cv. Tubaeformis
Basal part of culm looks like a gadarene trumpet with increasing diameter
11
P. pubescens cv. Heterocycla
Internodes below the middle part of culm are shortened and swollen in one side; adjacent nodes are oblique alternately and join together
12
P. pubescens cv. Pachyloen
Wall of culm is very thick so that it weighs 1.5–2 times more than that of a normal culm with the same diameter
voila tiré du link de sun , je n'aurais jamais du tomber sur ce tableau
