Captain Carmichael observes that * this elegant plant grows indiscriminately on the dome, the face 
of the table-land, and the plain of Tristan d'Acunha. It extends to the length of several fathoms, 
decaying from the base in proportion as it advances, and deriving sustenance by the radicles, which 
it pushes from time to time into the soil. It is entirely clothed with leaves, ending in a white fila- 
ment, which gives it in its fresh state a silky feel. "The spikes are sessile, cylindrical, two inches 
long, simple, bifid, or in pairs, equal in thickness to the shoot, and of a yellowish colour. The 
floral leaves are reflected after the dispersion of the seeds."
