Hab. Falkland Islands ; boggy ground on Hog Island, Berkeley Sound, rare, /. B. H. 

 Gramen humile, glaberrimum, repens. Oulmi prostrati, 3-4 unc. longi, parte ascendente bi- tri-pollicare, 

 nodosi, stolonil'eri, foliosi, glaberrimi, internodo terminali solummodo erecto, unifoliato. Foliorum vagina elongata, 

 profunde striata, glaberrima ; Ugula breviuscula, late ovata, membranacea ; lamina vagina brevior, patens, sub 1 unc. 

 lbnga, plana, striata, e basi latiuscula ad apicem acuminatum gradatim angustata, Panicula unciabs, i unc. lata, 

 interrupta, densiflora, ramis ramulisque brevibus, fastigiatis. Locusta glaberrimse, 1| liii. longa?, nitidae. 



To all appearance a very distinct species, allied to A. alba, var. stolonifera, but differing in the much smaller 

 size, coarctate panicle, smaller locustre and florets, absence of an arista, &c. 



4. Agrostis Falklandica, Hook, fil.; dense caespitosa, glaberrima, panicula gracili ramis erectis, 

 gluinis aequalibus ovato-lanceolatis acuminatis glabratis carina scaberula flosculis basi nudis i longioribus, 

 palea inferiore apice erosa truncata obscure 5-nervi nervo medio infra medium evanido, arista glumis bre- 

 viore v. nulla, palea superiore nulla, foliis radicalibus filiformibus culnio gracili erecto longioribus. 



Var. a, culmo folia bis terve superante. 

 Var. /3, culmo folia vix superante. 



Hab. Falkland Islands ; var. a and j3 in marshy places, on rocks near the sea, and on the lulls, 

 abundant. 



Gramen dense caespitosum, gracile, 3 unc. ad pedalem. Oulmi e basi erecti, foliis interdum duplo triplove 

 longiores, basi foUati, superne exemplaribus elatioribus longe nudi, laeves, obscure striati, glaberrimi, Foliorum 

 inferiorum vagina breviuscula, gracilis, striata, 1 unc. longa, superiorum elongata profuudius striata, 2-3 unc. 

 longa; Ugula membranacea, truncata; lamina angustissima, filiformis, erecta, herbacea, glaberrirna, 3-5 unc. 

 longa, apice gradatim angustata. Panicula |— 1-J unc. longa, ramis erectis elongatis paucifloris, in var. /3 

 brevioribus. Locusta? sub 1-J- Hn. longae, juniores puberulae, demum glabratae. 



Apparently a variable plant, its very narrow filiform leaves are characteristic of this species amongst its Antarctic 

 allies. 



5. Agrostis Magettanica, Lamk. (?); glaberrima, csespitosa, panicula elongata laxifiora nutante v. 

 inclinata, ramis pedicellisque scabridis, glumis majusculis aequilongis glaberrimis nitidis carina scabridis 

 rlosculo basi barbato fere triplo longioribus, palea inferiore apice truncata 4-dentata obscure 5-nervi, 

 nervo intermedio ad medium in aristam recurvam glumas superantem desinente, palea superiore inferiore 

 \ breviore, foliis planis longe lineari-lanceolatis gradatim angustatis, cubnis csespitosis vaginalis. A. Ma

 subequilonga. Panicula subcontracta, elongata, 3-5-pollicaris, nutans v. inclinata ; ramis vertieillatis, erectis, 

 divisis pedicellisque scabcrubs. Locusta sub 2 Hn. longae, micantes. Glumarum valvas subeequales, coinpressae,
