Falklands, etc.] 3. Agrostis prostrata, Hook, fil.j culmo longe procmnbente geniculate stolonifero, panicula erecta contracta lineari-oblonga densiflora, gluinis latiusculis acuminatis carina scabrida flosculum basi glaberrimum superantibus, palea inferiore truncata apice erosa enervi superiore bis longiore, arista nulla, foliis breviusculis planis glaberrimis v. obscure scaberulis.

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 breviore 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. Magellanica, Lamk. Illnst. Gen. n. 807. Poiret, Encycl. Meth. Suppl. vol.i. p. 207. Kunth, Agrost. p. 221. Hab. Strait of Magalhaens ; Port Famine, Copt. King.

Oulmi erecti, basi caespitosi, 1-ly pedales, glaberrimi, nitidi, herbacei, foliis vaginati, stricti, infra pauiculam scaberidi. Folia pauca ; vagina elongata, 3-5 imc. longa, profunde striata, glaberrima ; Ugula membranacea, oblonga, obtusa ; lamina suberecta v. patens, plana, hnearis, striata, gradatim acuminata, herbacea, vaginae suss 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, dorso seaberulae, acuminata?, flosculo fere ter longiores. Flosculi basi barbati. Palea inferior membranacea,
