"Gl. perennis, caespitosa, multiceps; fasciculis singulis caespitis polyphyllis; 

 foliis inferioribus ad vaginas reductis, foliis caulinis 1-2, omnibus planis, laxi- 

 usculisj e basi lata sensim angustioribus et oblique acuminatis, ligula protracta, 

 acutiuscula, leviterque denticulata; culmis erectis vel geniculato adscendentibus, 

 2-5 longis; panicula e folio caulino supremo longe exserta, brevi, angusta et 

 coarctata, rainis 1-2, brevibus, erectis cum rhachi laevibus et glaberrimis;

"Hab. In insulis Novaja Zemlja ad fretum Matotschkin legerunt Kjellman 

 et Lundstroem, 7-13 Julii 1875. 



"Habitum Glyceriarum minus bene exprimit et obiter inspecta potius Pais 

 quibusdam similis, sed characteribus, imprimis glumis dorso teretibus a Poae 

 genere recedit, nee reliquae characteres obstant, .quin ad Glyceriae genus referri 

 possit, nisi quod spiculae fere semper bi-florae et paleae dense villosae, superior 

 immo margine rigide ciliata (fere ut in Bromo). Habitu Dupontiis baud dissimilis 

 est, sed hoc genus glumis spicula aequilongis praeter plura abunde recedit. Itaque 

 hoc gramen singulare ad interim Glyceriae generi subsumsi, nisi forte proprium 

 genus constitueret." 



Glyceria Vahliana (Liebm.) Th, Fries. (Fig. A: 8-9). 



"Poa Vahliana (Liebm.) : gramen caespitosum spithamaeum, radice fibrosa, 

 culmo 3-foliato, vagina superiore folio 1| poUicari longiore, ligula producta 

 oblique truncata; panicula contractiuscula radiis binis solitariisque, spiculis 

 subtrifloris pedicellis longioribus vel aequilongis; glUmis subaequalibus-elongato- 

 lanceolatis obtusiusculis glabris obsolete-nervosis, basi apophysi parva instructis; 

 paleis glumas, superantibus valvulis inaequilongis, exteriore lineari-lanceolata 

 obtusiuscula obsolete 5 nervia, nervis pilosulis, interiore breviore apice bidentata 

 nervis 2 marginalibus purpureis ciliatis percursa, lodiculis oblique bidentatis, 

 germine elliptico obtuso, stigmatibus 2 plumOsis." Flora Danica, 41, tab. 

 2401; Kjoebenhavn, 1845. 



The species was found by Vahl on the west coast of Greenland, by Niakornak 

 near Umanak, at an elevation of about 700 M. 



Lange (Conspectus Fl. Grqenl.) adds to the diagnosis: "foliis flaccidis, 

 planis, acutissimis; glumis parum inaequalibus, purpurascentibus, margine 

 apicem versus albomarginatis." 



Glyceria Langeana Berlin (Karlvaxt., insaml. under svenska expeditionen till 

 Gronland 1883). 



"Humilis, dense caespitosa; foliorum fasciculis intravaginalibus; foliis 

 rigidiusculis arcuatis; culmis rigidiusculis vix folia superantibus; paniculis et 

 spicuKs glabris; glumis inaequalibus acutiusculis; paleis obtusis exterioribus 

 apice laceratis." 



North Greenland: Kangaitsak. 



Glyceria angustata (R. Br. sub Pod) Fr.i(Fig. A: 14-15). 



By Robert Brown (Chloris Melvilliana,p.223) the species is described as follows : 

 "Poa angustata, panicula simplici coarctata lineari-lanceolata, locustis 



4-5 floris, gluma inferiore dimidio minore, perianthiis apice erosis: valvula inferiore 



basi elanata lateribus glabriusculis, foliis angusto-linearibus. 



"Desc. Gramen 4-6-unciale, glabrum, erectum; radice fibrosa. Culmi 



foliati, basi quandoque divisi, laeves. Folia angusto-linearia, plana, acuta, 



glabra, laevia; vaginae subcylindraceae, laeves, suprema folio proprio longior,
