In flower and fruit this species hardly differs from 7. cannabina, Linn. f., of 
which it may only be alocal form. This is especially true of the form (Hildebrandt, 
1981), which Dr. Pax has described as sub-sp. glaucescens, which can hardly, as 
regards foliage, be separated from TZ. involucrata, var. intermedia, Mill. Arg. 
(7. tripartita, Beille, not of Schweinf.) and is only distinguishable by its strictly 
erect habit.
