Falklands, etc.] Radix fibrosa, subrepens. Culmi 8-10 unc. alti, basi inclinati, glabcrrimi. Folia radicaba, pauca; vagina unciabs glaberrima v. obscure pilosa ; lamina subulata, involuta, 2-polliearis ; caulinorum vaginae elongatae, tumidee, striates ; lamina brevissima, subulata. Spica li-unciahs, fusco-purpurea, Glumee J-unciales, recurvaj, basi flosculique pube seabrida, pilis brevibus intermixtis vestita.

Very distinct from the former (than which it is a good deal smaller) and from any other species, and may be recognized by the pubescence of the florets ; its general appearance resembles the European H. maritimum,

A very variable plant, and all the more perplexing from some of the larger varieties differing more in appearance than they do in reality from the common European T. repens. The lower palea is generally, but not constantly tridentate at the apex, with the middle tooth sometimes produced into a short awn; it is, however, always hairy, as may be seen in Siberian, Arctic American, and Rocky Mountain plants, which latter, indeed, are sometimes villous. The North American specimens are generally larger than the European. This species is also a native of Cape Fairweather on the Patagonian coast, and exceedingly abundant throughout Fuegia and the Falkland Islands.

The habitat assigned by D 'Urville to this plant renders its being indigenous very probable.
