*) H. Halleri tubulosum Gaud. herb. ! (Wall.), very nearly allied 
to H. nigritellum Arv.-Touv.! deserves further observation. H. nigritellum 
resembles H. armerioides, but the stem and Is are much more hairy, the invol. 
ls more obtuse. The stem (in the specimens found on the Simplon by Wolf) 
is div. below the middle or in the lower quarter into 2 long 1-headed branches. 
— H. ustulatum Arv.-Touv.! is near to H. nigritellum, but the invol. is 
less villous, the stem on the other hand very glandular.— H. dasy trichum 
Arv.-Touv. which, according to the author, is hybrid between II. villosum 
and glanduliferum, is still more hairy and almost without glands; the caul. 
Is are more developed and the invol. ls narrowed-acute.
