Caules in arena prostrati, crassi, uni-pluri-pedales, ramulos emittentes plurimos breves dense foliatos. Folia 
opposita, subconnata, fere pollicaria, crassiuscula, ciliis baseos latitudine folii longioribus. Pedunculi vix polli- 
cares, monocephali, bracteis paucis setaceis rigidis. Involucrum cylindraceum, 4-5 lin. longum, squamis acutis 
latis magis quam in affinibus lateraliter imbricatis. Ligule involucro fere duplo longiores; flores disci squamas 
paullulum superant. Acheenia fere 3 lin. longa, angulata, glabra. Pappi sete longiores achzenio breviores, 
ali multo minores, ex eorum numero 4-5 seepius basi dilatatee, ceeteree subulatee, scabride. 
A much coarser plant than most species, with larger heads of flowers, and 
growing in the dark sand of the beach, at a temperature of 126°. It was gathered 
in the same situation by Galeotti, and is his No. 2063.
