Ad A. hispidum Baker non Thunherg accedit, habitu robustiore, 

 ramis magis foliosis, foliis latioribus, pedimculis brevioribus sat 

 differt. 



Herba robusta erecta rigida, ad 60-90 cm. alta ; rami simplices 

 strict! hispiduli striati foliosi, internodiis 1-1*5 cm. longis ; folia

 like bracts. Wilms' specimen in herb. Kew was distributed with a
