Poa alpina var. vivipara, Grinnell Ld., Lady Franklin Bay, 

 Greely, and 



Poa alpina, Nth. Side of St. Johns Sound, H. E. Wetherill. 



Now my father, Mr. Morten P. Porsild, who has seen the 

 specimens of both collections in the Gray Herbarium, Cambridge, 

 Mass. tells me that the first represents a depauperate, viviparous 

 culm without basal leaves. To him it seemed to be quite identical 

 with my viviparous form of Poa pratensis. 



The other specimens, subsequently to Wetherill's Identifica- 

 tion, have been referred by the staff of the Gray Herbarium to 

 Poa laxa, but the specimens are probably badly developed forms 

 of the polymorphus Poa glaiica or of P. arctica, as already suggested 

 by SiMMONS 1. c. 



28. P. arctica R. Br. — Not as common as the preceding. 



29. P. alpina L. — Upernavik Ejland, Kuk, Patorfik, Alianaitsiinguaq, 

 Atå, Påtut, Atanikerdluk, Naujat and Sarqaq. Common when 

 sufficient moisture and humus is available. 



30. P. abbreviata R. Br. — Agiussuit and Qaersuarssuk, 



31. P. glauca M. Vahl. — Common everywhere. 



32. Puccinellia Vahliana (Liebm.) Scribn. & Merr. — Upernavik 

 Ejland, Hare 0, Alianaitsiinguaq, Påtut 670 — 770 m. and in the 

 lowland. 



33. P. phrijganodes (Trin.) Scribn. & Merr. — Kuk, Patorfik, Atani- 

 kerdluk. 



34. P. angustata (R. Br.) Rand. & Redf. 



35. P. — var. vaginata (Lge.) Holmb. 



36. P. tenella (Lge.) Holmb. 



37. P. arctica (Hook.) Fern. & Weath. 



(Of these 4 Puccinellia species I have several specimens, but, as Holm- 

 berg's interpretation has not yet been published, I will not venture to 

 identify them.) 



38. Festiica ovina L. — Common. 



39. R. brevifolia R. Br. — Ujaragtorssuit 70°44', Patorfik and Qaer- 

 suarssuk.

41. Agropyron violaceum (Horn.) Lange. — Påtut, Atanikerdluk. 



var. virescens Lange. - — At Påtut common on some raised clays 

 near the shore. Hitherto not recorded north of 61° Lat. N. 



42. Elymus arenarius L. var. villosus E. Mey. — Upernavik Ejland 

 rare. Common on the shores of the Nugssuaq Peninsula. 



var. compositus Abrom. — Atanikerdluk.
