Nuce acute et confertim echinata (pallide cinereo-fusca, 2 mm lata) a 

 reliquis optime distinguitur. Accedunt spiculae propter squamas magis 

 acuminatas patulasque squarrosae, pallide rufescentes, spicule masculis 

 squamas suas nonnihil superantibus quinquefloris plerumque quaternis 

 cum spicula foeminea glomerulam referentibus.
