Falklands, etc.] FLORA ANTARCTICA. 383 



Gramen foliosum, 3 unc. ad bipedale. Culmi robusti, basi pluries divisi, prostrati v. repentes ; pars 

 repeus validus, saepe pedalis ; pars erectus per totam longitudinern foliosus, compressus. Folia plurima, distiche 

 inserta, elongata, coriacea sed non rigida ; vagina aperta, folio brevior, compressa, striata ; ligula brevis, fimbriata ; 

 lamina culrnuru paniculamque superans, plana v. dorso subcarinata, utrinque Isevis, 2-4-lin. lata, gradatini in apicem 

 acuminatam angustata. Panicula 2 ad 8 unc. longa, erecta v. paulo inclinata, -| unc. lata, subcontinua v. verti- 

 cillatini interrupta. Locusta late ovato-oblongae, 3-4-flores, sub 8-lin. longa;. Oluma superior 3-nervis, inferiore 

 l-ner\i longior, flosculis breviter pedicellatis brevior. Palea inferior ovato-lanceolata, acuminata, concava, vix 

 carinata ; nervo medio dorso superne cib'ato, inferne barbato ; flosculo superiore infimoque apice aciuninato, in- 

 tegerrimo, duobus intermediis apicem versus utrinque uni-dentatis ; palea superior inferiore \ brevior, bifida. 

 Antliera lineares. Caryopsis oblonga, cylindracea. 



The commonest grass in Kerguelen's Land and a very valuable one, affording a rich and abundant fodder. 

 The tendency in the palea to become toothed on each side towards the apex, and the distichous, long, and particularly 

 rich foliage, show its affinity with the Tussock and with the Festuca foliosa of Lord Auckland's group, which chiefly 

 differs from this in its larger panicle. These three grasses are certainly representatives of one another, and all 

 typical of moist Insrdar climates ; their northern analogues are evidently the F. Bonax, Lowe, of Madeira, and 

 F. albida, Lowe, of the same island.

Radix stolonifera. Culmi 2-4-pedales, graciles, erecti, glaberrimi, striati, politi, remote nodosi. Folia pauca, 

 culinum vaginantia, patentia, flexuosa ; vagina pedales, teretes, superne hiantes ; ligula brevis, transversa ; lamina 

 plana, utrinque Isevis, vagina brevior longiorve, gradatim supra medium acuminata. Panicula 6 unc. longa, laxa, 

 inclinata ; ramis paucis, elongatis, filiformibus, versus apices divisis. Locusta fere -i-unc. longa;. Glumes flosculis 

 pedicellatis basi nudis breviores. Palea inferior dorso convexa, supeme prsecipue pilosinscida, superiorem bifidam 

 paulo breviorem amplectans, nitida, purpureo-picta, 5-nervis, nervis scaberulis. Squamula 2, profunde bifida;. 

 Ovarium obovatum, superne pilosiun ; styli basi discreti. 



A tall and handsome grass, allied to the South Brazilian F. fimbriata, Nees, in which the palea; are not awned, 

 and the leaves are convolute. In general habit it resembles somewhat the European F. elatior.

Hab. Strait of Magalhaens ; Port Famine, Capt. King. 



Capt. King's specimens are nearly two feet high, in which respect only they differ from ordinary forms of those 

 of British growth. The leaves are erect and involute.

 locustis majusculis pedunculis compressis longioribus multi-7-9-floris, gluims inaecmalibus lineari-oblongis
