 intricatis composito obducti, glandulis sessilibus parvis lutescentibus crebris, vulgo quoque stipitatis 

 majoribus aculeolisque instructi, fusco-purpurei vel sub umbra virentes, autumno subpruinosi, interdum 

 tuberculis exasperati. Aculei in parte inferiore crebri, inaequales, breves, recti, subulati, superne sparsi,
