Caulis 30—40 cm altus subflexuosus, superne dense floccosus et pilis 1—1,5 mm longis 

 albis mollibus mediocriter numerosis obsitus, basin versus minus floccosus pilosusque. 

 Folia ut in H. Rionii, sed in margine subtusque densius pilosa, in nervo dorsali effloccosa 

 pariter ac in petiolo breviter crispo-villosa, supra intense glauca prasino-viridia glabra v. 

 marginem tantum versus pilis dispersis rigidiusculis munita, immaculata. Acladium 5 — 10 cm 

 longum, rami primarii 1 — 2 ( — 3) monocephali rarius furcati, capitula (1—) 2—3 ( — 5). 

 Involucrum fere ut in H. Bionii sed praecipue basin versus densius albopilosum breviter 

 subvillosum, squamae subangustiores, interiores viridi-marginatae apice obscuriores. Pedun- 

 culi dense floccosi pilosique apice obscuriores et glandulis teneUis brevibus dispersis saepis- 

 sime in caulis partem superiorem descendentibus obsiti.
